750m #2

Jul 10 2015

Friday 2x750m on choppy water: Good learning

Thursday’s training was a late evening session. Friday’s training had to be an early morning session. I don’t like to do it that way, especially two high rate workouts after another, but there was no other way. Friday afternoon to Monday I will be without a car, which despite the perfect public transport in Brno makes everything more complicated, our rowing club being 2km of hiking from the nearest tram stop and my work being on the other side of town (23km from the rowing club).

So I rolled out of bed at 5:30 and drove to the rowing club.

Very cold conditions compared to a few days ago. 10 degrees C and mist on the water. Cross wind and chop. Interesting to see mist and chop and wind at the same time, but it truly happened. Should’ve taken a picture of it. Also interesting about our lake is how light wind from certain directions can create seriously choppy conditions. We only have flat water with zero wind. Anyway, about 15 minutes into the session, the mist disappeared and the wind strengthened.

The plan: 2x750m / 12 min rest (1) 34spm, (2) 37spm.

The real plan: As the training schedule is written with double/quad in mind, I have to lower the stroke rates of the high rates sessions when I do them in the single. So I decided to row at 32spm and 34spm, and row them “as the first 750m of a 1km race”. I also decided to focus on achieving that rate by focusing on technique rather than trying to achieve a certain pace. Rate and technique over pace. With the chop and crosswind, splits wouldn’t be fast anyway.

3km warming up with some high rate bursts and a practice start. Had to reset CrewNerd after 2km because it stopped measuring distance. The reset fixed that, luckily.

First 750m with race start, then settle down to 32spm and count strokes to 80. The first half was slightly calmer than the second half, during which I had a couple of instances where my blade hit a wave and I was slightly off balance. The good old lactate rush was also present at the party. End result was 2:47 (1:51.6 pace) at 31.9spm (38max) according to CrewNerd.

To be honest I didn’t feel much like doing another one.

Twelve minutes of rest and I had to decide. Either I continued down the lake to the finish, turn around and would do the second 750m in even more choppy conditions. The alternative was to turn immediately and row to the narrow north end of the lake and do the higher rate interval in calmer water. Calm, flat water certainly helps to achieve 34psm and is easier when you’re tired (or, said differently, gives more flattering splits), so that was a very attractive option. On the other hand, doing the high rate interval in very choppy water would probably be better in terms of race preparation for next week. Trebon lake has a similar chop-sensivity as ours. So I chose the first option. During the rest I had time to think about a way to survive the second 750m. I played with the thought of reducing it to a 500m and avoid the dreaded lactate rush. Or to row 500m and then just paddle it out.

But all that didn’t feel all right, so I had to really find a way to survive. This is what I came up with:

Race start + ten strokes, then

10 strokes focus on clean tap down in the chop, then

10 strokes focus the high rate recovery (speed but calm on the slide), then

10 strokes focus on a light catch, not too strong on the legs in the first part of the catch, then

10 strokes focus on a good back swing, then back to

10 strokes tap down, 10 strokes rate, 5 strokes light catch, 5 strokes back swing, 5 strokes tap-down, five strokes high rate

I did exactly that and it did wonders. I ignored the stroke rate and pace on CrewNerd and focused on these things. The conditions were much more choppy than in the first interval and I thought I was going slower, but when I finished, I found myself looking at 2:48 (1:52.1 pace), 32.8spm (37 max). Not bad pace in cross-wind and being tired.

Rowed the cooling down in victory mood. This has been a very useful, educational session. I knew the lesson but apparently had to live through it today to reinforce it:

  • Thou shalt focus on thy technique to go faster. Nothing else.
  • In the race, thou shalt not focus on how far the competition is ahead of thee, but thou shalt focus on rowing faster thyself
  • Thou shalt give thyself something to focus on, and the lactate bite will hurt less

It’s the reason we have coxes, right? In uncoxed disciplines, there needs to be a voice in your head reminding you of it.

3x5x30a

Jul 9 2015

Thursday: Chop = Slow Splits but useful training

5:00 – up and drive to Prague.  Covered the 200km in 2 hours roughly. Good. At km 87 a standing truck in the left lane. Managed to switch lane smoothly but if there would have been a car next to me, I would have had to break hard, and you never know if the guy behind you isn’t making a phone call or texting, or sipping a coffee. Not pleasant.

Meetings in Prague. Left around 3pm. Made it to the rowing club at 7pm. Lots of traffic jams. Tired.

Windy. Chop.

The plan: 3x(5×30″)/8min rest. (1) 30″ 34spm / 30″ rest. (2) 30″ 36spm / 45″ rest. (3) 30″ 38spm / 60″ rest.

Here’s the summary. In the remarks column I put what CrewNerd told me, because at these short intervals it differs slightly from the spreadsheet analysis.

First set of 5×30″ was done with tailwind and increasing chop. Second set of 5×30″ in headwind and decreasing chop. Final set in tailwind and increasing chop.

What do I mean by that?

The north end of the lake was wind from the north and medium chop. The south end was wind from the same direction, but heavy chop. So in the first set, as the intervals progressed I entered more difficult water to row. I turned with about 2 minutes rest to go, and started doing the 36spm intervals into headwind. Last set was again rowed with tailwind.

Chop doesn’t speed you up. It was good exercise though to row in the rough at high rates. I imagined an end sprint situation at next week’s Masters Nationals, where there can be the same difficult conditions.

Related to my post of yesterday, I have been thinking a bit about effects which could explain why a “pull on the recovery” combined with a prominent and fast catch help the boat speeds. One hypothesis is about drag and boundary layers, combined with the rocking or tilting of the boat … which also could explain slowing down in choppy conditions, as I saw waves going over the deck regularly. Just a hypothesis for now. Perhaps the slowing down in choppy conditions is just due to balance and precision difficulties …

Monday: Family Quad

kunka

Monday was a bank holiday. We were in Pardubice visiting Romana’s family. My brother-in-law, Romana, Lenka and I went out at the rowing club in Pardubice. We took an old Empacher quad on the river Elbe and did 8km of nice steady-state.

The view on the castle on Kunětice Mountain is quite nice. kunka2

What a lovely row: Saturday ORCA mix 2x 1000m

As the temperatures on Friday evening started to drop below 30 degrees, we fired up the barbecue and had a very nice dinner of Roodbaars (Atlantic redfish) from the grill. This fellow weighed 2.5kg at the fishmonger’s, so the three of us (Lenka, Romana and I) had plenty of very tasty fish. A simple salad to accompany it and (perhaps a little too much) French white wine.

We decided to launch around 9am, when there are still reasonable temperatures, and the lake hasn’t yet turned into an amusement park.

Absolutely ideal conditions. No wind. Flat water. Almost no swimmers. The boat rentals weren’t open yet. My training plan said “Death by Lactate” but as I was rowing with Romana, who hasn’t done her share of 1km trials yet, I decided to just do a 95% effort on the 1000m.

So we launched our Salani “ORCA” and did two kilometers of warming up. Then a test start plus five strokes which were perfect. Very concentrated and very nice.

Then we rowed one kilometer to the buoyed 2km and got ready for the start. The plan was to do a 95% effort. Hard start plus ten, then down to 30spm and only increase it a bit in the final 200m.

Start was ok but worse than our practice start. After ten strokes I lowered the stroke rate. A quick glance at CrewNerd, which told me I was doing 10spm. We must have been rowing so  smoothly that we confused CrewNerd. After about 200m CrewNerd came back and I was indeed rowing at 29.5-30spm.

The half way point was passed without the dreaded lactate bite, and we continued our well coordinated 30spm.

29 degrees C, 1023mbar, humidity 53%, wind speed between 0.2 and 1.0 m/s.

With 200m to go I brought up the stroke rate to 33spm. We stopped 2 strokes early, and cruised through the virtual finish line at 3:42. Happy with that. At the Masters Nationals in 2014 we were third in 3:44, same warm and windless weather. This year’s edition will be very interesting. Hauk and Zizkova will remain in masters B, the Dekanovsky’s we don’t know, and we will be starting in C. Already in C last year there were Masatova and Zeman, who rowed a 3:44.

So, no excuses to go slow, two weeks from now!

We did a 3km cooling down followed by some swimming in the lake, gave the boat a good wash and then headed to the town centre for a coffee on the main plaza, and a visit to some bookshoppes.

Now indoors to survive the hottest part of the day. No rowing planned for tomorrow, or perhaps a lazy single scull early in the morning.

Thursday: Warm Quad Training

Last day of the three Crazy Quad Days.

The temperatures were well above 30 degrees C. Brno’s girls, gathered around the lake, were running out of clothes to shed. Yours truthfully had to park 500m from the rowing club, because everybody was gathering there for the late afternoon.

So we weren’t on the water before 6:30 pm and some of were under time pressure. We did a 3km warming up, then a 750m at 34spm, then 3250m rest and finally a 750m that was supposed to be at 37spm.

It was the first time we were running above 30spm for a substantial distance. With all the little boats and swimmers the water was very lively. There was a slight crosswind, and our bow man had to turn around almost every stroke in a desperate attempt to avoid swimmers and drunk people on small boats who have veered into the 2km course.

I wasn’t entirely happy about the sculling. In the first one we were too short, and we had some big wake from a tourist ferry in the middle 250m. We got a bit more stroke length in the second run. But of course in that second run tiredness was kicking in and I wasn’t able to stroke higher than 34spm without severely compromising the rhythm.

After the second interval, we immediately rowed back to the club. I did a 10 minute cooling down on the erg.

Then strolled over to a fish restaurant along the lake to join a work related dinner. Very relaxed evening.

This morning I spent 3.5 hours at the traffic police, to obtain this:

The license plate for the new trailer!

No rowing today. A rest day. Bought a big fish to put on the barbecue tonight (Atlantic redfish).

Wednesday for Project 2: Mixed Quad Steady State

It’s quad craziness. Almost every second outing I do is in a quad. But we have to, because some members of our mixed quad are going on vacation, so the next time we meet it will be a few weeks before Belgium.

We did 12km of steady state with catch drills at every turn. steadystatequad

Good session.

Today, the ladies of our mixed quad, my wife Romana and Lubica, will attend the funeral of Eva Velešíková:

eva_velesikova

Eva was a big driving force behind women’s Masters Rowing in Brno. Lubica and Romana have trained and raced with her. As a member of Masters International, a group of women raiding Masters races, she won two medals at Masters Worlds in Varese, in 2013, when she was already diagnosed with pancreatic cancer and told she had 1-1.5 years left. After her husband died, she traveled around the globe, and remained very active, optimistic and energetic until a few months ago. I don’t know her closely but I feel enormous admiration for her.

She passed away last Saturday, when I was out in the mixed quad with two ladies who have rowed with her frequently.
