Some racing (Brno Spring Races)

IMG_1721
Brno lake in the morning. Before the races

Today there were one-day races in Brno, the so-called “Spring Races”. Usually haunted by big wind and heavy chop, today’s edition was a very pleasant one with nice temperatures and a light headwind.

I was in the second race of the day, the Men 2x heat. I rowed with a member of my brother-in-law’s club, Vojtech. Never trained together. No idea how it would go. We just launched early and did a few race pace pieces and practice starts, then went into it.

Four boats at the start, first three to go to the final. Sounds easy. But which boat will be the slowest fourth one? The foreigners from Slovakia? The young guys from Lodni Sporty, the rival club on the other side of the lake, Tomas and Ondra from our club, a 32 year average age “Masters” double, or we, 36 years average age?

The start was worse than our practice starts but we were in front anyway. The race was very interesting. I stroked a nice, not too high 30 spm and in the first 250m it was four boats on a line. Then the Lodni Sporty guys started to fall behind. That was a surprise. They are both quite fast scullers, and young as well. So be it.

We continued the race, which turned out to be a “watching each other” game. Nobody went full out, except Ondra and Tomas who beat us on the finish line. We came third. The young guys from Lodni Sporty lost in front of their own boat house.

Turns out that Ondra was told that he had to beat me in order to qualify for the final. This was told to him under the assumption that Lodni Sporty and Slovakia would qualify. He just remembered “beat Sander” so with 300m to go he opened the attack. We didn’t respond, of course. Happy to row a second race.

Our official time was 7:35 in a light headwind. The stats are a little slower because I forgot to stop/reset CrewNerd. Vojtech was a much better rower than I expected. Also, we are about the same height. He’s 20kg heavier than I and in bow which is not ideal, but stroke length and style turned out to be quite identical. Meanwhile, our boat house started to come alive. Lots of people. Lots of anticipation.

IMG_1725 IMG_1726

Around noon it was time for Romana’s girls to row their first race. After Hořín, they formed a quad with two girls from other clubs who finished in about the same time. Today, they raced against Pieštany from Slovakia. Here they are before the start. Our girls wearing light blue, Lenka with the pink head band:

IMG_1729

Meanwhile, our young new trainer was preparing for trainer’s exam. My son Dominik and his double partner Štěpán were full of confidence and waiting for their race, and a new member, young Víta, was just doing single practice”

IMG_1737 IMG_1736 IMG_1735

Races continued. A boys pair returned from racing. The boys’ trainer was out on the lake on the launch. The girls launched. Young Víta ended his practice.

IMG_1739 IMG_1742 IMG_1744 IMG_1746 IMG_1747 IMG_1749

My son Dominik and Štěpán launched their double to race. They are on a practice double called “Trabant”. These boats were made before 1989 and they row with Aluminium sculls. Definitely the oldest boat in their race, but who cares. The stroke has cool sunglasses, so everything will be fine. They were confident they would win. They were about the only people in the world who thought they could win this race.

IMG_1755

Romana and I went out on the launch. I took a picture of the race buzz on the Lodni Sporty boat house, on the other side of the lake:

IMG_1758

We watched 14 year old Tereza come second in her race (also wearing cool sunglassed), our confident boys were waiting for their race, I took a picture of our club house (we will paint our club’s name in big fat letters on that white wall next week) and a picture of the lake, amazingly well-behaved for spring races.

IMG_1761 IMG_1763 IMG_1764 IMG_1765

And there was the race of our girls. They were leading and won!

IMG_1768 IMG_1769 IMG_1771

Yay! First medal in the family. Then it was time for our confident boys’ double. Five boats in their race.

They were totally unprepared just a second before the start. Then they started out and were leading. Then the stroke caught a very bad crab, they almost collided with the boys from Lodni Sporty Brno. They recovered and continued, rowing in second place. On the finish line they managed to push their bow ball in front and won!

My son’s comment: “Masakr”. I think you can get the meaning of this Czech word. Here’s a photo of them at the starting line in blue. The boys from Lodni Sporty in red with bow number 5.

IMG_1772

Romana and I were happy. We rushed back to our club and waited for the victorious crews to return to base. First, the girls.

Then, the boys:

Then a quick lunch in the club house. The TV is tuned to Youtube rowing from the London Olympics.

IMG_1787

Then some more race watching and some other crews from our club returning from the hard work:

IMG_1790 IMG_1795

Meanwhile the younger kids were playing happily:

IMG_1797

Then it was time for Lenka and Iva to get ready for their doubles race. For this event, they selected a Fluorescent Orange theme. I guess they wanted to “highlight” the importance of the race.

IMG_1798

Well, they were in the winning mood and went on to win their doubles race. Hurray! Facebook-tired, some girls didn’t want to get photographed. Still a great picture:

IMG_1799

Meanwhile, yours truly showed up for the Men’s 2x final. Six boats at the start. A stronger headwind than in the morning. Of course we, the oldest average aged, were in the underdog position. I was OK with that, just had a wish to beat our club president Tomas and his partner Ondra, who had sneaked ahead of us in the heat.

We had a really good start and Vojtech told me later we were leading. I don’t know. At the start of a race I make a point of not looking left or right, just concentrating on the rhythm.

Then the young men started to lead by a length and suddenly we were last. About 400m into the race we passed Tomas and Ondra quite easily and we were still not losing contact entirely with the field of young men.

In the end we finished 5th in 8:55, a bit slower than in the morning even though it felt like harder work with the heavier headwind. Funny enough, my heart rate didn’t go so high:

We returned to the rowing club happily. A good race. Then we all went into the club house to have a drink. We went through some old club documents. Here, for example is a document from 1939 honoring the Consul to the Kingdom of the Netherlands for his long time membership of our rowing club:

And finally, last but definitely not least, my daughter Lenka (two medals I am so proud) making fun of her picture taking father:

Another steady state row in the single

Not much to report. Except that the XGPS160 failures are starting to annoy me. The XGPS160 as an external GPS is good for two things:

  1. More accurate and frequent GPS updates – less need for smoothing, more lively pace feedback
  2. Save battery of cellphone

But having to reset the bloody thing twice during a training is a bit much. Looking at the data, I have been rowing half of it with a non-functioning XGPS160 anyway:

April CTC

The training plan featured a hard distance row, so today was the ideal date to replace that with April’s CTC:

2 minutes , 1 minute rest – from standing start

4 minutes, 1 minute rest – rolling start

6 minutes, 1 minute rest – rolling start

8 minutes

Simple. I knew I would be immune against the temptation to row the shorter intervals faster. When rowed in this order, one has to respect the final, longest interval. Distance wise, this looks like a 5k. There is not an abundance of rest, so I decided that my 5k pace 1:50.5 or slightly faster would do it. I started with a 3k warming up and then went for it.

A windy outing

A quick row during the lunch hour. I did manage to take some wind speed measurements. It was very windy today. It was interesting to do the measurements. The device measures wind speed and show the instantaneous, average, and peak wind during the measurement.

  • First measurement: average 1.9 m/s with a peak of 3.7 m/s.
  • Second measurement: average 2.8 m/s with a peak of 3.8 m/s.
  • Third measurement: average 1.5 m/s with a peak of 2.4 m/s
  • Fourth measurement: average 1.9 m/s with a peak of 3.5 m/s
  • Final measurement (back on the dock): average 3.8 m/s with a peak of 6.1 m/s.

SportTracks synthesized an average wind over the nearby weather stations and informed me that the average wind over my session was 2.1 m/s with a maximum of 3.6 m/s.

The final measurement was taking over 2 minutes. The other ones were shorter, of course. Anyway, today was a windy day. Lots of chop as well. Here is how the lake looked at that final measurement:

wind 002 wind 004

The row itself was a steady state row with interruptions. Here is an ugly plot. My algorithms don’t do corrections for paces slower than 3:00.

figure_1-5

I used an average wind speed of 3.0 m/s. Quite conservative. Looking at the data, it seems that the GPS160 had it’s hickups again, 35 minutes into the row. 🙁

In the single on a cold lake

Early row. Just steady state with a focus on technique. Windy and “medium” choppy. I still have difficulty believing what the weather stations around the lake tell me, so I am going to visit a shop specializing in weather equipment this afternoon, just to see what’s available.

I alternated 18spm and 20spm every 2 minutes. Nothing else to report. It was slightly colder, around 6 degrees this morning. Oh yes, I am 44 now … 🙁

Guessing 2 m/s as wind correction gave me around 200W. I think that is about right. Mind you, this is all power. Comparing to the erg display of a static erg will be difficult, because the erg doesn’t measure the power you spend bouncing up and down the slide, which at 20spm is about 20-30W (estimated). I may have to spend some time to calculate real erg watts. I am curious.

1k Season’s Best

We are a few days into the second half of April, so little time left to complete all the Nonathlon challenges, and the CTC.

Today, I scheduled a 1k PB attempt. The PB is 3:19.2. First, a Fletcheresque warming up. I never remember the exact Fletcher stroke rates and durations, but roughly 20 minutes with a few bursts should do it. The rule is that you start sweating a bit.

figure_1

Then, on to the 1k.

figure_1_1k

figure_2-1k

Interesting to see that my drive length is well over 1m40 today. I thought 1m35 was more normal for me.

Here are the statistics

06|00000|00:01.7|00:00.0|33.0|180.0|180.0|00.0

That adds up to 3:19.6 for the real 1k. I still have to perfect my algorithms to get the exact statistics from the Painsled stroke data. Here is the proof:

unrotated

First 500m no issues, but then I started to have difficulties and saw the occasional 1:41. In the final 250m I tried to short slide and rate up, but somehow it didn’t happen. I had a few strokes at 1:42. The very last stroke even was a 1:45 one.

Well, it’s the first 1k, at the start of the sprint race season. I should really do a PB attempt some time in June.

Then I did a 5k gentle cooling down at 2:05-2:10 pace.

In the double

The sun was shining today. The tourist season has started, which means that these guys did a first celebrational round of the lake this morning:

Brno tourist boats. Rowing club Lodni Sporty in the background

Also the electric boat rental has started. We had the first incident this morning where a coxed four with our 13/14 year olds got rammed by a young couple (holding a baby!) in an electrical rental boat. According to our trainer, the tourists suddenly changed course. We have a broken oar and one of our rowers has bruised ribs. Unfortunately, the kids and their trainer didn’t realize they should have treated this as an insurance incident, so we’ll end up paying for the repairs ourselves.

The sailing club had a race for their kids.

We went out in a double. Lenka and Iva rowed next to us in their double and both boats did a lot of technique drills.
