A 6km with competition
Today we planned to row a 6k. On our lake, this has to be a 6k with a turn in the middle. When we arrived to the lake, there was mirror flat water. Even when we pushed off, the water was flat. During the warming up, the wind started to blow and within ten minutes there was a nasty chop, which, as the 6k progressed, turned into a very nasty chop. I had a sweater in the bottom of the cockpit, which was completely soaked after the row.
A measured 6k. Three boats. A youth 15/16 single, a youth 15/16 pair, and me. We started with 1 minute intervals, first the young single, then the young pair, and finally me. I argued a bit with the youth trainer about the location of the start of the 6k. He has been timing 6k all his life with a starting point at a certain cliff. I have measured out the 6k with a GPS and I told him we had to start at the red buoy, which is about 150 m earlier. In the end I gave in and started from the “traditional” starting point, but when I passed the finish line, CrewNerd told me I still had 300m to go, so I kept going to complete the 6k.
Final result according to the trainer, who subtracted 30 seconds for the turning:
- Youth single in 25:02
- Me in 25:05
- Youth paid in 25:10
Not sure about the absolute times, but I believe the order is ok. I tried to row towards the pair but couldn’t get closer to them. I guess they tried to row away from me and couldn’t increase the distance.
The row was slow and nasty. I should have put my oarlocks a bit higher. I was slamming into the chop. In the first half, the head wind slowed me down significantly at times. In the second half, with tailwind, I didn’t manage to rate up as much as I wanted. It started fine with paces around 2:02 – 2:05, and I had hope that I would get the average pace down to 2:13. I didn’t.
I have been a minute faster on this course, but that was with flat water.

New toy – and more python
Got my PM5 today.
The row was a warming up, a 3x20min at 190W and a 2km cooling down.
I also captured the row with painsled and exported both CSV and TCX files. The TCX files read fine into SportTracks. In contrast to CSV files that I have from other people who run painsled, my files don’t have HR data
EDIT – I reported this to the painsled developer (Rick) and he fixed it within 12 hours. See the plots in all their glory:
It’s already the third monitor for my Concept2 Model C. Here are the first two:
More Python
My python software ran great on my PC. Turns out the command-line scripts didn’t work too well on other people’s computers. Over the weekend, I did some testing, using my son’s Windows10 computer with a clean Python (Anaconda) install, and on my old Linux netbook. Greg also helped greatly by running subsequent updates on his macintosh.
Turns out Python packaging is quite confusing. In the end I got it all working. Now it should install easily for people who have Python and easy_install. Just installing Anaconda and then easy_install rowingdata should do the job. You get command-line scripts that should work on every platform.
It’s all documented on: https://pypi.python.org/pypi/rowingdata and http://pythonhosted.org/rowingdata/
