500m/1km/2km, Garmin and CrewNerd stuff, and Race evaluation
Today I wanted to do a 4x1km OTW, but the Renegade Rowing wordpress blog (http://renegaderowing.com/2015/05/12/rowing-wod-51215-500m-2min-rest-1k-4min-rest-2k-post-splits/) inspired me to change it to:
500m @32 s/m (2k-1)
2min rest
1k @30 (2k)
4min rest
2k @28 (2k+2 to 2k+4)
It was quite windy when I launched. I did a “long” warming up of 3km, to Rokle and then back to the start of the 2km Albano. In the 500m with strong headwind, I had difficulty holding the prescribed 30spm stroke rate, and the pace was around 2:10 at best. So I was very surprised to suddenly see 2:02 in the Crewnerd App when I finished. Didn’t give it too much thought.
I did take a bit longer rest to drink a bit, reset CrewNerd to “just row”, remember to hit “start” on CrewNerd, and turn the boat.
One kilometer with tailwind. Got started, and had to check my course a few times because there was a windsurfer in my rear view mirror who was doing unpredictable things. At one point he fell in the water and then tried to get his sail up again. When I checked Crewnerd, I suddenly was down to 500m to go, but with a time of 1:30 for the first 500m.
Hm, something must be wrong. The XGPS160 LEDs were on. What to do now? Do an additional unrecorded 30 seconds? Somehow I didn’t feel like it. But I did make a mental notice to do the 2km from start to finish in the Albano, and not stop early.
So I did. The 2km was a real struggle. The Masters pair was next to me, probably doing steady state, but still it felt like a victory that I could row away from them. With the strong headwind and waves, it was difficult to keep the stroke rate at 28spm.
Here’s how rough the weather was:
Here are the statistics according to CrewNerd:

And here is my trajectory according to CrewNerd:
Notice the strange loop at the beginning of the 1km?
Statistics according to Garmin+Crewnerd
So I decided to do an experiment and merge the Garmin data with the CrewNerd data, taking position and speed from Garmin, and stroke rate from CrewNerd.
Here are the data:
| Time_ | Pace__ | _SPM___ | avg HR | max HR | _A/D | DPS | Remarks
| 15:30 | 02:53.1 | 18.9 | 129 | 148 | | 09.2 | Warming up
| 02:02 | 02:12.9 | 27.2 | 162 | 177 | | 08.3 | 500m headwind
| 04:43 | 04:26.0 | 20.1 | 134 | 174 | | 05.6 | rest
| 03:00 | 01:58.6 | 25.5 | 161 | 177 | | 09.9 | "1000m" tailwind
| 05:35 | 03:30.2 | 19.9 | 135 | 175 | | 07.2 | rest
| 09:10 | 02:18.6 | 25.7 | 173 | 181 | | 08.4 | 2km headwind
| 13:32 | 05:18.9 | 19.4 | 128 | 180 | | 04.9 | cooling down
Not sure if the SPM is right. Might be an artefact of merging the data.
Here’s the revised trajectory:
And the colorful graphs:
I guess it was smart to take the Garmin Forerunner as a backup.
Race Evaluation
So it’s time for the race evaluation.
The Quad
We basically had no opposition, so it was just a test of how well we could row together. We were focused. The race plan was to settle down 10 strokes after the start and row a light and easy stroke. We did just that. I decided to not take any stroke coach and just stroke this one on feel. Romana measured a 34spm when we were 250m from the finish. It definitely didn’t feel as an all out effort. Our time of 3:03 is of course fast with the tailwind and the (light) current.
We should expect tougher competition but it was a good start.
What worked: Race plan execution, light stroke. We were confident.
What didn’t work: –
What would I do differently next time: We have to train doing a 10 hard stroke section in the middle and do an all out last 200m.
The Eight
What can I say. We got the 2 guys who didn’t make the selection for the local team and we got their worst eight. Still we won. We managed to pass the boat, take a half length lead and defend this, winning by a margin of 0.5 seconds. Good race experience.
What worked: We won, despite everything. Apparently the six of us have enough horse power.
What didn’t work: The rowers in the bow didn’t hear the cox.
What we need to do differently: We need to make kilometers in the eight. We need to have a boat with a coxbox. We need an experienced cox.
The Single
A nice race despite the pressure I loaded on myself. I wasn’t the fastest out of the start but I was confident and focused and rowed well. More a training than an all out 1km. I should expect tougher opponents in the rest of the season. The time of 3:39 was of course fast with tailwind and current.
What worked: I win effortlessly. I was focused and nothing distracted me (launch wake). I thoroughly enjoyed the racing. I was rowing a relaxed stroke. I was confident.
What didn’t work: I need to discipline myself the evening before the race. Strictly one glass of wine with dinner (or zero), not eat too much, and go to bed early.
What would I do differently next time: I still need to do a hard, all out 1km. Should train this a few times before the next race.

Double on waves
Went out in the double with Radek today. He’s a self-taught sculler and he thinks he’s not good, but in fact he’s an eager learner and a pretty good rower.
As we are racing together in two weeks, I decided we would do some rate ladders. We would do 1 minute on, 1 minute off, the “on” minutes starting at low rate and gradually increasing.
In the first run there was tailwind, but there also were pretty big waves in the second half of the lake, so we stopped at 28spm in the tailwind part. When we turned around we discussed technique a bit and we agreed to focus on “hands away” and try to get it right >70% of the strokes. We succeeded. The wind gradually calmed down during the practice but we weren’t able to take the stroke rate much above 30. Still, I think this was a great success given it was the first time we were pulling hard together.
After the two sets of “1 minute” we did start practice, and then we fartlekked back to the finish, turned around and rowed to our boathouse. A very nice session.
