I should start out by saying that I'm terrible at pacing myself. But I have spent the first part of this year working on running slower and biking slower. I have not been in the pool in 2 months.
Anyway to today I decided to start working hard over 20 - 25 miles on the bike. When I work hard I ride near threshold the whole ride. Well today kicked my butt. I started out into a head wind for 10 miles. That put a hurt on me right there. By the time I got home I was happy to be off the bike.
Obviously I need more fast time.
And my tri seat hurts my butt more then my road bike.
