Didn't plan on it, but almost a sprint triathlon today.
Start - about 38F
Finish - about 50F
Jumped on the mtn bike to go to the rec center to swim, not planning on a ride. Swam quite a bit - more than you would for a sprint tri, then got back on the bike - street clothes - and started up the path - just kept going and ended up with 20 miles (13 needed for a sprint tri), then walked a couple of miles - 3.3 needed for a sprint tri. So, I am short about 1.5 miles for my sprint tri today
