Ah... that's cool! How awesome of him to even give it a try... biking to running.
I bet he's toying with the idea of a tri...but might not want to admit it. Maybe he was giving it a "test run"?
My boyfriend started doing tri's because of me... and yea, he's a lot better than I am. Shoot, he can RUN! Unfortunately, it looks like he will be more successful than I will be.
