Yesterday, I managed to bike for 20 miles (RT commute to work), swim 800 meters at lunch, and then run a 5K on a treadmill at the Y in the evening. Now all I need to do is to be able to do all three, one right after another.
And yes, I'm tired today.
p.s. I meant "triathlon"; just because I work at a University doesn't mean I can spell.
