No offense taken Kempie! The technique was moderately hideous to watch.
I tend to row very differently in sprints than I do with longer pieces. Not good, I know, but it's not as night-and-day as it used to be. Usually I row at about 24spm. Next time I give a go at a sprint like this, I'll try it with a slightly higher drag factor and a lower stroke rate. Also better pacing could probably cut 0.5-1.0 seconds off that time. But the next dragon to slay is better 1k and 2k times.
Chris Lampe, those are standard foot straps. Just push down on the heel strap to get out instead of loosening the toe strap. Most of the time I row without straps actually, except when trying to set a pr like this.
