Two 3.6-mile city rides.
5K run. I ran more of the distance than I have previously, getting nearly back to my building before "Hail, Hail."
Reading my triathlon book, I learned that the Olympic distance is much closer to the sprint than a midpoint between sprint and Ironman: 1.5K swim, 40K bike, 10K run. As sore as I am after a run, I shouldn't say I am confident I can do a sprint triathlon, but I kind of am; what I should aim for is an Olympic-distance event.
