Training for Red Bull Head of Prague – turning an eight
So we signed up for this race, to be held next weekend.
The course is interesting:
Four kilometers downstream towards the center of Prague, then a U turn (in the eight) and finally two kilometers against the stream.
They also have a fun video with beautiful shots of eights racing into the great Prague skyline:
We will compete in the Mixed category. So on today’s session we decided to
- Row a 3k at head race pace
- Work on our turning technique
First, we did a 2k warming up:
Then on to the 3k:

That was a good workout, and I think we found a sustainable pace for the 6k, especially given that we have some team members who are significantly older than I.
The next part was trying out the turns, which looked pretty spectacular as a few times we came quite close to one of the big tourist boats, our cox demanded a turn in three, two, one, and we did a water splashing turn. Quite a few of the tourists took pictures. Here is our course:
We had the feeling that we were improving, but looking at the close-up charts, the turn took us around 30 seconds every time. In the first one, we started going straight too early, though.
That was fun! Doing the turn, we have to remember to lean on stroke side so that the bow side can take quick strokes and actually turn the boat, while we on stroke side are trying to keep our blades and oarshaft under water and help. Big risk of ejection crabs for us on stroke side.
There was another fun aspect of this row. I recorded it with my NK SpeedCoach, then used the NK Android app to download the data to the phone and send it to rowsandall.com by email. By the time I was showered, I had the workouts on the site, including the charts, and I have been able to write this blog including the charts on the iPad, without the need to boot up the computer to run the LiNK PC software. There had been a NK app for over a year, but it didn’t export the Empower metrics, nor did it export coordinates. I like a little map with my Row, and I like to look at Empower data (although today they weren’t there, as the eight is not equipped with Empower oarlocks). The export worked like a charm. I find that very cool, although I must say that the user interface in the app is not the most intuitive. (Which may be a case of the pot telling the kettle it’s black, as the rowsandall.com user interface has been criticized as well.)

Thursday – Short and Intensive
I hesitated whether it made sense to go to the lake. In Brno-Slatina, where my office is, the flags indicated a strong wind. I called Romana, and she reported normal chop, nothing unrowable. When I arrived at the lake, the normal chop had changed to high chop, but by the time I was launching, it was getting calmer again. This was going to be a short, but intensive workout:
Again, I lowered the SPM by 2 because I row in a single.
The low power section 4 minutes into the first 2k is caused by a turn:
On this map, it’s the turn to starboard just before I row through the “Brněnská přehrada” text (after crossing the boat line connecting U kotvy to Osada.
This is also where tailwind turned into tail/cross wind and I had to turn the single slightly to compensate for being blown into the buoy line. This is what that did to Wash:
A jump from 12 degrees to 14-15 degrees. It confirms my feeling that Wash is very sensitive to water roughness and other external factors.
Drive length and effective drive length were pretty OK, and at least consistent. Intervals 1 and 3 were rowed in tailwind and the middle 1k in strong headwind. I was afraid that would be visible in the drive length (being shorter in headwind), but it isn’t really.

Pretty happy with the numbers here, considering the strong tail/head/crosswind and chop. I aimed at 26, 29 and 32spm and it seems I succeeded. Pretty hard work but pretty consistent, I think.
Back at the dock after 42 minutes, including warming up and cooling down. That was good, because I did have some accumulated fatigue from earlier sessions this week.
