Thank Marni and Trek 420. The coach says I have crappy tires. My bike is 5 years and I don't remember having them replaced. He also thinks I need something adjusted on chain/gear. I wonder if the second flat was bc I was going downhill and riding the break. Either way, 3 in one week is too many.

I've been reading up on the gear issue... I have a triple but it's shimano tiagra, so maybe I need to upgrade?

This is a very expensive sport.

Two days after the ride and I am still so sleepy and sound like an old lady who's smoked for 40 years. What is that about?
