Do trust your abilities. Have confidence in your training. Thank heavens I decided to take the training setup off my skates to check them the night before leaving for Atlanta. The next morning I'm waiting in the skate shop. Yup, that would be my skates.
Extreme heat does remove frozen bolts.
It also melts wheels, fries bearings and brings out lovely new colors in aluminum frames. Don't try this at home. I would not have enjoyed looking for a skate shop with a blowtorch in Athens the night before the race. So I did okay by the first rule. I didn't do so well by the second rule.
