Longtime CrossFitter Mike Neill rowed 1000 meters in 3:37 at Ergomania 2009, the indoor rowing championships held at Seattle U last weekend. Way to go, Mike! He competed in the "Men's Veteran A 1x (50-59) - 1000 meters" division, in which he was the only entrant (and took first place).
Other men were rowing near Mike at the time, but Mike had by far the most solid stroke and maintained his stamina until the end. All that CrossFit and rowing classes have paid off.
The event had about a bazillion divisions, which you can view here.
