3x2k. You decide how fast to go and you decide how many minutes to rest in between but the total score is the time it took to do all the rowing and all the minutes rested. So once you begin the 1st row the clock is running.
My strategy was to try to keep an even pace and really only break to reset the monitor.
1. 2k - 7:56 minutes 1:59.1
2. 2k - 7:56.9 1:59.2
3. 2k - 7:57 1:59.3
