Two pieces for a Masters Eight
The temperatures have increased to above 30 degrees C, but luckily we were rowing in the evening.
It had been s hectic day. After a four hour drive back from Racice, we found our poor cat in distress. It had injured its tail and during the twelve hours it had spent alone, it had sprayed blood all over the house. So instead of relaxing in our garden we took care of the wound (which was not easy, as is evident from the claw marks on my arms) with help of a rowing friend who lives nearby and is a vet. On Monday we visited him in his office for a check, some injections and antibiotics, as well as a cap to prevent the poor animal from biting its painful tail again.
So when I arrived at the rowing club, my rowing friends were still discussing the European Championships, but I had already moved on to another world.
Anyway, we are racing the eight coming weekend so it is time to get to business. The training plan prescribed 1500m pieces at 26spm but the crew wanted to add a race pace piece. The compromise was one 1500m and one 750m.
I gave the SpeedCoach to the cox because his CoxBox Mini doesn’t show stroke rate. I told him to not touch any buttons on the SpeedCoach and started its recording when we still had the boat in slings. Unfortunately I forgot to switch the screen to distance, so the cox had only elapsed time and stroke rate. He managed well and just did the pieces by estimated distance from landmarks. For the 1500 that was easy: from the 2k start to the Lodni Sporty club house. For the 750 it was a bit more difficult.
But rowsandall.com can deal with that. Sitting on 2 seat the SpeedCoach didn’t record my heart rate. However, I was using the Garmin watch to capture that. After the row, I imported the Garmin data through Strava to rowsandall.com, uploaded the SpeedCoach data and did a data fusion merging the NK pace, SPM, and distance data into the Garmin workout.
Then, I used the Interval Editor and the interactive plot to determine the start and end times of the pieces and here is the result:

Ignore the power data. It’s a conversion from pace using the equation for the Concept2 erg and when you’re in the eight it overestimates the power. I will update the site to do a better power estimate for OTW rows.

Corvée is the Dutch word for drudgery and roei is row, so roeicorvée would be rowing drudgery.
I wanted to row late in the evening, when the temperatures start to drop from the high of 30C. However, by the time I wanted to drive to the rowing club, the sky was black and the weather forecast looked like this:
Not so good, in other words. So I opted to row the steady state session on the erg. Roeicorvée. It was a good decision. The hailstones were the size of golfballs.
One of my Strava followers had talked about Kinomap. This iOS app shows you footage of rowing while you are pulling on the erg. I thought it would make the erg less boring so I installed it on my iPad and rowed the first 2k with it. That is, I played the only video of a 2k effort that was available on the free version and rowed while it played, covering s little over 2400m while looking at some single sculler on a brautiful lake.
For data capture, I had Painsled running in the background, but connecting Kinomap through BlueTooth actually threw out Painsled, as I discovered after the row. Bugger.
But Kinomap syncs automatically to Strava, except that it didn’t transfer heart rate data from the PM5. Here is the workout after import to rowsandall.com from Strava:
So I tried to look at pricing of Kinomap but couldn’t find a way to subscribeor find any pricing info on Kinomap’s website or in the app. I thought about connecting Kinomap through the USB cable (using the connector cable for the iPhone) but the connector csnle is very short and I had no way to support the iPad next to the PM.
So I rowed another 30 minutes of rowing drudgery, wiped off the sweat from the handle, my hands snd my face, dialled up a 5k and rowed on. Here are the PainSled plots. These ones are missing SPM values because Painsled has corrected a typo in the CSV column header (stokes instead of strokes) without informing the developer at rowsandall.com. I will fix that asap.
All really slow as you can see. Tomorrow: another row in the eight.
