Saturday – Bled Masters Worlds B1x

For Friday’s fantastic C 1x race, I wasn’t nervous at all. Saturday morning 9:00 was the scheduled time for my B1x race. Between 2am and 6am I didn’t sleep much. I was constantly replaying Friday’s race. I guess it was a consequence of being so close to winning. 

As usual in such situations, I dozed away just before the alarm clock rang. I did a quick breakfast in the hotel, already dressed in race gear, and then cycled to our car. This ride through and around Bled is a perfect warming up. There are a few short climbs, and it has the right duration. Romana rode with me and helped me, so the pre race routine was efficient and calm. I checked my heel straps. I was hydrated. I just felt tired. 

Romana snapped a pre-race picture and I rowed up the very beautiful Bled lake. The usual two loops and I arrived just in time for the start. I wasn’t nervous. At this point, I have enough race experience to be calm and focused. But I was tired. I had the feeling that everybody around me was going to be faster than I. Their practice starts and short pieces at race pace looked all really fast.

The weather was colder, and a bit calmer than on Friday. The cross wind was virtually absent. Ideal conditions. 

Attention/go. When I checked, about 10 strokes later, I was somewhere in the middle of the field, with the Dutch guy sticking his bow out a bit further. I shortened the high power phase and tried to rate down to a sustainable pace. 

Half way, passing the island with the church, was somewhere in the middle of the pack. And that was really the last time I checked. I was in lane 1 and some of the fast guys were over on the far lanes, so I just focused on my rowing and my SpeedCoach. The SpeedCoach was not telling me good news. I was having trouble keeping the power over 300W and Work per Stroke was way under the 600J value that is my target. 

As I neared the 250m to go mark I could hear Romana. She was standing on a little balcony-like pontoon right next to lane 1. As you near the finish, the lake suddenly becomes very narrow, and in lane 1 you almost have the feeling that you are going to hit the bank. The little pontoon there is an ideal point to see the rowers from very close and cheer for them in the final 250 meters. I also heard a woman shout “Hop hop hop” and I assumed that was for a competitor. 

I focused on a point far behind my stern and just tried to squeeze out my remaining energy, pulling good strokes. I finished fourth, or so I thought. Rowing back to the rowing center, Natasha Kral took this great picture:

 

Natasha Kral, the wife of Andreas Kral, a friend from the rowing scene in Vienna, has many great pictures of Czech and Austrian rowers on her Facebook page. By the way, my club CVK Brno were the first in the Czech Republic to have the club name on our long sleeved race shirts. Now many clubs are doing it.

At the rowing center, I performed the hardest part of the race, carrying the boat back to the rack. When I returned for my blades, I met Romana who told me I was second, which I didn’t believe. Apparently, I had raced a fantastic race catching up and passing two guys in the final stretch. I was completely unaware of that, but that is maybe better. Here are the official results which confirm my wife’s assessment:

Result MB1x

The Dutch guy had rowed a controlled race, but I had beaten the rest of the field. My time was worse than on Friday, but seeing my name on second place immediately made me feel better about the effort.

Here is a comparison between the two races in the single:

It was raining and I was cold. Romana and I rode back to the hotel. There was no more racing for us on Saturday, so we rested, then went to Bled for a coffee and a Kremšnita. Then we spent some time in the boat area getting the single and two pairs ready for transport. I also picked up a Roseman single belonging to a German guy, for taking it to Brno for a repair. 

Got a message from Quiske that they finally had their experimental virtual reality system ready, so I had to try it out. Kristina took a few pics of me trying out the future.

I shall be honest. I don’t see the benefit over streaming the images to a normal big screen or external monitor. We rowers are used to taking quick glances. It is nice to see the metrics in front of you but I feel the Virtual Reality glasses cause eye fatigue, are unpleasant when you are sweaty, and currently need too much pre row fiddling with. Streaming the metrics from your rowing app to a big screen does make a lot of sense, though. 

The weather got slightly better, so we went to the grandstand to watch some racing. 

Zuzka’s water bottle rolled into the lake and her trying to recapture it was an entertaining intermezzo between the races:

She succeeded eventually. No risk of a water bottle causing a racing crew to crab, and the beautiful Bled lake was spared of plastic waste.

Around 4pm, I had finally digested the kremšnita so we headed to Grajska Plaža,  a restaurant with a lake view, for an excellent late lunch.

Wr ended the day on the promenade, but this time Romana and I went to bed really early. With the mixed double race and the drive home, Sunday would be a long and tough day. 

Just because I just discovered them, I am adding two photos by Natasha Kral, taken back in May at the Piestany races. I won the single there.

Friday – Racing continues in Bled

In a sense, this was the day I had been preparing for for two years. At the end of the afternoon, I would row my Masters C 1x race.

But first, the eight! Through Facebook, I had linked up with some French rowers and promised them to row an eight in the C age category. Racing at 11:13, the meet up was at 9:50 in front of the place where you get bow numbers. It was interesting, as I didn’t know any of them, but in the end we found each other. They were a jolly bunch. We spent about 25 minutes counting to eight, because people were constantly disappearing and reappearing (toilet visit, greeting friends, other vague things that are apparently highly important an hour before race time) and figuring out the distribution of bow and stroke side rowers. In the end, one of the French guys called all stroke side to his side. So we had a group of five and a group of three, so I ran over to bow side. 

Then we determined the order. Nobody wanted to row stroke seat, but eventually a volunteer was found, and then we just lined up behind him in random order.

Then we went to find our boat, an older Sims (?) eight. Carried it off to the dock, waited for boat and crew to be identified and checked and en launched. With three minute race intervals and eight racing lanes, you would expect the dock to be a mad, chaotic mess, but to the credit of the organizers everything went calmly and there was hardly any waiting. And that is getting 160 boats on the water per hour.

I was seated on 7 (or 2 as the French called it) behind stroke seat. Our stroke did his best but I am not sure thst we didn’t have a better stroke on one of the other seats. We did have a lovely and very good cox, and because 2 in the crew didn’t understand French and some of the French didn’t understand English, I got to listen to every command in two languages. We did a few practice starts and ten stroke pieces and discovered that setting the boat was our biggest challenge. We also decided to row a slightly lower stroke rate.

 21556963_352838858486485_476714497_oWe were last out of the start and we consolidated that position. For the entire race, we were trailing about one length behind the next boat and were unable to take them back. We didn’t lose any ground either, we just rowed and rowed and that was it. The photo was taken just before the finish line. I am on the far right. Stroke seat is outside the picture. This photo made it to the World Rowing site. My first picture on World Rowing!

Spirits were high though and our cox made a fun picture:

21469831_10213570386444834_1929868580_n

Everybody was happy!

Then I had a few hours before my main event. I helped Romana with her ad hoc French/German/Scottish/Czech quad.

And a quick post race picture, using beauty filter 4:

 

With all that and some race watching it quickly became time to prepare for my own race.  With the large distances between our boat rack and the water, this requires careful planning. Carry sculls to dock: 7 minutes. Drop bag. Five minutes waiting in line. Warming up run. Fifteen minutes. Waiting in line to get bow number. Five minutes. Back to boat. Seven minutes. Carry boat to dock. Ten minutes. Romana was racing the double thirty minutes before me, so she wasn’t around to help me. 

I was about to take my last sip of water, some fast sugars in gel form (for their placebo effect) and carry the boat to the dock. I put the single in slings and checked the heelstrings. Damn. They were not secured. So i had to take out the entire footstretcher and readjust the heel strings. Without heel strings in order, I wouldn’t pass the boat safety inspection (and rightfully so). So that was another few minutes lost. Not a big deal, except that I forgot to take my sugar and water, so I was pretty thirsty rowing to the start.

The good thing was that I wasn’t nervous at all. I didn’t know any of the other competitors in my heat and could not predict where I would end up. I was hoping to row in front, i.e. The first three boats, but who knew?

After two loops between the 2k point and the start at 1k I was ready, waiting for my race to be called to the pre-start. I was racing in lane 1, where it is difficult to see the people in lanes 7 and 8. 

“Race Uniform. Come to the start.”

I backed into the starting pontoon and aligned the single slightly diagonally because of the crosswind. 

“Two minutes.”

I knew that in Bled, two minutes is about 30 seconds. 

“Quick start.” (That means they are not calling out the boats individually. Good for me. They should always do that.)

“Attention.”

Then a long wait, then the starters flag went up, then a long wait. 

“Go!” We were off. The start was good. I was with the others.

“Ding ding ding dimg ding!” A loud bell called a false start, and we stopped and rowed back into the starting pontoon. Lane six got a yellowcard. I don’t blame him. The long waits between attention and ready are torture, especially in a cross wind.

I had a little chat with the boy on the starting pontoon and then concentrated again,

So we repeated the “quick start”, “attention” and “go” and my second start was superb. The first one was good but this one was better.

About 150m in I was in first or second position, with lane 2 next to me and the others slightly behind. As we continued, the gap between the two of us and the rest of the field widened slightly. I took a quick glance to the far left to check lanes 7 and 8 but they were OK as well. I brought down the power on the SpeedCoach to values in the 3000-400 range, which I knew I could maintain, and battled on.

Lane 2 was not rowing away from me, but he passed the 500m line slightly ahead. That is where I opened my first attack, and I managed to pass him and lead by … perhaps 10cm. 

“Don’t mess it up, I really want to win.” That is what I thought. 

Unfortunately, lane 2 had a similar intention and he slowly caught me back, and 250m before the finish we were even. I rated up. I guess he did as well. Everything became very painful. I stopped checking his position and just rowed and rowed. I screamed, I think, of pain, a few strokes before the finish line, and in the end I didn’t win. A small but significant margin. 

I looked at the Brazilian in lane 2. It was clear that he had had to work very hard for his medal. We were both still breathing hard when the other boats crossed the line and we were told to clear the finish area immediately.

Result MC1x

Slightly disappointed, I rowed past the victory ceremony pontoon. Then it dawned on me that i had rowed a pretty damn good race.

 

In the next heat, my friend and long term opponent Kazimir was racing, and he was leading. I cheered for him and he won! In absolute tikes, he beat me by a second, which is good for him, because I beat him by a large margin at our Masters Nationals. 

Carrying the boat to the rack, I nearly collapsed and two friendly Dutch guys carried the boat for me for the last 300 meters. Then I walked back to the rowing center, picked up my bag, bought a beer, had a chat with Mike, and picked up my sculls. That beer tasted good.

Romana had come fourth in her doubles race, but apart from her it felt like the entire Czech community had watched my race. Lots of congratulations, it almost felt like a win. 

When I found Romana, we pushed our bikes up the hill to the car park, took some clean clothes and rode back to the hotel for a shower. We had a pretty nice dinner in Bled and then joined the festivities on the promenade.

I tried to limit the wine and get to bed early because I would race at 9am the next morning. I didn’t succeed entirely. It is also good to relax with friends.

Thursday – World Rowing Masters Regatta – my first race

On Thursday, my brother-in-law Tomas and I would race our B 2x race. Tomas had come over the evening before, would race with me and then spend a few days biking in the Alps. When we launched, it suddenly started to become windy, and the lake became a little choppy.

We haven’t done many sessions together, but I was hoping that our race experience from Trebon would compensate for that. Unfortunately, it didn’t.

Our start was great. This was the only race of the five I did on this regatta where the traffic light system was actually working. I did go off when I “felt” that it would go to green. We were slightly early. The guy on the starting pontoon looked at us in surprise, but the race was started and they didn’t call us back.

Rating down to the middle part of the race, we were not able to find a good rhythm. We were fifth, but a few boats were just in front of us. In the second 500m, I had hope that we could pass one or two boats, but unfortunately that didn’t happen. Too bad. Fifth place.

Our time was very disappointing. With this tailwind, we should have been able to go under 3:30. We clearly didn’t manage the chop.

Result MB2x

I thought we were sixth because we beat two boats. According to the official results we were fifth. The Vikings didn’t show up.

Romana and Veronika rowed the A 2x and were happy with a fourth place.

In the evening, I walked up to the Triglav hote, where a small crowd of rowing data fans gathered. Before the talk, I took a picture of the boat area (above) with a million boats. Our boats are not in the picture. They are more to the left.

The seminar on data analytics for rowing was a success. I presented for about 30 minutes, and then we talked for about an hour.

Tuesday & Wednesday – Travel & First Training in Bled

I haven’t blogged in more than a week. The reason is the World Rowing Masters Regatta. There was simply so much racing and stuff going on and no time to blog. But there was certainly a lot that I want to blog about. So here we go. A series of posts about the most important regatta of the season.

Tuesday

Finally! We are off to Bled. Picked up the rowers at a parking in Brno, then the trailer at the rowing club. Our lake showed its most mirror-like water, so we were tempted to unload the boats and go rowing, but traveling to Bled won.

IMG 0073

 

The drive was uneventful, luckily. I would hate an “eventful” drive with a boat trailer. The only point where I was a bit nervous was when we chose the left lane at Graz, and were diverted into a very narrow temporary highway lane, separated from upcoming traffic with concrete blocks. Romana was driving and she managed the 7km of driving in this lane with perfect calm. Millimeter precision steering, with a few cm on both sides of the trailer, or so it seemed to me.

Driving into Bled town, my passengers started to make phone calls to announce our arrival and go for a training in the afternoon.

Too early.

We were caught by the organizers and put on a temporary trailer holding area.

IMG 0075

 

IMG 0076

 

After about an hour of waiting, we were allowed to drive to the venue. So, all in all the wait wasn’t long, and it was a good move by the organizers. If they hadn’t done this, they would have created a traffic jam of trailers on the venue.

Boats were unloaded, and the official Bled 4×4 pulled our trailer to the trailer parking. Romana and I hopped on the bike and rode to our hotel. We checked in, took a shower, and then went into Bled for a nice dinner.

Wednesday

I went for a quick training in the morning. The official training times were between 8am and 10am. First, I took some time to rig the boat. Then I had to carry it about 500m from our rack to the dock. I did two loops of the entire lake. A few practice starts and a few 20-25 stroke intervals.

In the afternoon, we rode around on the bike. We had a nice lunch on the lake. The racing had already started, but we weren’t racing today, so it was nice to see the boats rowing their warming up.

 

IMG 0078

After that, we watched some races from the grandstand. I saw a regular follower of my blog win, and watched Tom Carter race the Masters A 1x. I also took the opportunity to look around the booths and chat to rowing electronics vendors.

Goodbye Prygl

Prygl is the nickname of the Brno reservoir. Today was the last training. Tomorrow we’ll load the trailer and on Tuesday morning, we’ll drive to Bled.

On the map, it looks like an easy drive. The familier route to Villach. Then turn left to the Karawanken tunnel, pop out of the tunnel on the Adriatic side of the Alps, a couple of hair pin turns, and we’re there.

Romana and I launched at 5pm in quite rough conditions. We decided to take shelter in the Gorge. In the Gorge, the water was flat but the wind was unpredictable. We did a 5 minute rate ladder, 3 minutes at 26spm, 1.5 minute at 30spm, 30 seconds at race pace, in mostly headwind conditions. We weren’t entirely happy. It’s a fine balance. Sometimes we get that light catch and we’re very close to flying. Sometimes, the timing is off just slightly, and it’s a slog. You don’t see it in the boat speed immediately, but the rowing is without a spark, it’s not playful, and it tires the body much faster than when the fire is on.

We turned around at the Castle, and on the way back we did a few start practices and short race pace pieces.

Then we crossed the lake in a fantastic strong tailwind, with very heavy chop. I thoroughly enjoyed it. Romana enjoyed it less, but she wasn’t as uncomfortable as usually. I just need to set the oarlocks a touch higher when there’s chop, on our double.

Oh, and I forgot to blog about what I did on Friday and Saturday. On Friday, I cycled to work, through the rain.

At work, I moderated a strategy workshop for the full day. Then I cycled home, through the rain.

On Saturday, the weather was slightly better. I took a lazy day and the only exercise I got was a short cycle tour with my son Robin. We rode into Brno, had a drink at the Selepka pub in the park, and then rode home.

On Saturday evening, we went to the movies, to see a new movie by Jan Sverak. The English title is “Barefoot on Stalks” and it is a great, slightly nostalgic, movie, telling the childhood memories of the director’s father, from occupied Czechoslovakia in WW II, seen from the perspective of a child. Here is the trailer.

So … goodbye Prygl. We’re going to Bled.

SUP (or SUB?) PEAK

The last week of the summer school vacations and beautiful weather.

I knew rowing in the afternoon was going to be asking for trouble. More windy conditions, and, mainly, lots of recreational boats. So I drove to the lake in the morning, forgetting that I had given the boat house keys to Lenka and she hadn’t returned them. I did open the gate with the phone, but then I had no way to enter the boat house. So I lost 25 minutes of driving through Brno, took my loss and drove to work, arriving there at 7am. I left a little earlier. What a luxury. On Tuesday I had a 6 hour call and then another call, ending after 8pm and no time for rowing.

On the way to the lake I picked up a more permanent way to mount the phone to the boat:

It’s a mount made from three RAM elements and it allows to clamp the mount to the tube behind the footstretcher, putting the phone behind the wing rigger in a place where I can comfortably see it during the entire stroke.

The workout for today was

“1-3x(10×30″/15″ full out). Pace may fade.”

A fade it did. Of course, that was the purpose of the workout. Get deeper and deeper into the pain cave, muscles full of lactate, and get “used” to this, and row hard despite the pain, as you have to do in the final 300m of a 1k race.

I programmed this as irregular intervals in the SpeedCoach, but that limited the number of repeats to 10, so I altered this to two or three sets of 10. (In hindsight, I could have taken a slightly different approach to programming the intervals and arrived at 2 or 3 sets of 12. But optimizing my SpeedCoach workout programming skills is not really my goal.)

myimage (35)

 

myimage (36)

As there was a lot of chop and pretty strong wind, I rowed these in the gorge. The first set (top chart) with tailwind, and the second set with headwind. This is a tough workout, and it was complicated by the fact that I had to constantly check the position of hordes of Stand Up Paddle (SUP) boarders. I did manage that in the first session. In the second session, a SUP caused a late start of the second interval. The dip in power in the third interval is rowing through a turn. In the seventh interval there was a lady in an electric rental, on the wrong side of the river, steaming straight towards me. I counted on her seeing me, but when I did check behind me, six strokes later, she had managed to turn around her little boat and was rowing in the same direction as I, completely unaware of the fact that I was going much faster. I managed to stop just before my bow ball hit the back of her boat. You can see how the power fades.

As the intervals are just a few strokes short, the average power and pace are influenced a lot when you miss the start of the interval by one stroke. Here are two charts taking only the strokes above 30spm.

I was worried a bit about drive length. It averaged out to 102 degrees for the “on” strokes. Not too bad, but about 4 degrees shorter than normal. For the headwind series. For the tailwind series, I reached my usual 106 degrees.

With the Android phone in the new holder, I took the opportunity to record Quiske boat and seat acceleration. In the warming up, I had to wait for the phone to allow me to unlock it. With iPhones, I had no issues with fingerprint recognition, but the Samsung is terrible. And the problem is, after a couple of attempts, it locks up for five minutes. I have to remember to switch off the fingerprints and use a pass code only.

What I was curious to see is how seat velocity coincided with a few characteristic (for my rowing) acceleration wiggles in the middle of the drive/recovery cycle.

boat acc

So this is boat acceleration for 6 selected intervals (first, fifth and last of each set).

And here is the average seat velocity:

seat speed

You can see that the wiggles start when the seat comes to rest, so that means it is the back swing, arm pull, arms away, back swing part of the stroke that is causing it. If you look careful, you can also see that the acceleration wiggles are stronger when the seat speed is high for a longer duration. That happens when I have a more pronounced “legs first, then back” stroke. I wish there was a way to extract a metric describing this. Then I would use rowsandall.com’s Trend Flex and other tools to find correlations with rowing efficiency. Now, I can look at pretty charts and wonder which of the two styles is the more effective.

To get an impression of reproducability, I also took charts with all individual strokes.

During the cooling down, I rowed straight through about 30 SUPs, and I almost collided when I tried to row around a wind surfer who suddenly changed course. Let’s hope that this season is the peak of the SUP hype.

Although I have to say that I haven’t met a person on a SUP who isn’t enjoying himself, is happy and friendly, and doesn’t mind the splash when I do an emergency stop.

Monday – Speed work in the double

A short training in the evening. When I made it to the rowing club after work, Romana had already rigged the boat and cleaned it after transport.

Going into the taper for Bled, I wanted this one to be an intensive but short training. I chose my beloved 45″/R75″ format. I personally think our boat moving skills are good, but Romana is unsure about some of the technique changes I have made. Due to rowing with the power meter and analyzing the metrics that the Oarlock has revealed, I have been making gradual changes in my technique, and the issue is that Romana hasn’t changed with them, as she was not rowing for a few weeks in June/July due to back issues.

After a 2k warming up with some 10 stroke bursts, we did 6 intervals. After the fourth one we had to do a quick turn because there was too much traffic ahead. Paddle boards, wind surfing, sail boats, and a pair from the other rowing club, who are also preparing for Bled. Actually, that ladies’ pair was rowing in the wrong direction, against the traffic pattern. I did point that out to them after we had completed our intervals. Told them a crash would have damaged two boats and ruined our plans for the World Masters Regatta.

Here is the summary:

After my “friendly” chat about the traffic pattern, we turned around and rowed a “500m” against the pair. Actually, we were leading by several boat lengths after about 400m when Romana had enough of constantly turning around to check the position of paddle boarders, pedalos, sailing boats, and wind surfers, and we continued to row slowly.

I had put the Quiske sensor on Romana’s scull. So here are some charts, from all the 45″ intervals as well as the 500m.

When I put the sensor on the scull, Romana joked that she hoped that I wouldn’t remove her from the selection based on her rowing data. Of course, I praised her great rowing style. (And I don’t think there is anything wrong with these curves.)

What is interesting is to compare the scull horizontal/vertical angles of a stroke between the single and the mixed double. I don’t realize it any more, but we do row a shorter stroke, as Romana is a bit shorter than I am. And here are the data:

single vs double

The outlier curve is me in the single.
