Mike, are you running on that employee team? If so, good luck and hope to meet up with you.
For the rookie on Leg 1, it';s too late now but best advice is "only join the team on the condition you don't have to lead off."
That said, I am a 2-time Leg 1 idiot and here's what i think. I tape the balls of my feet, and I have worn light, cushioned trainers (adidas Boston, the 3-yr-old old model with disco-shine stripes) and substantial racing flats (adidas Rats Racers) without foot trauma in either case.
Asd for the execution, just keep turning 'em over -- at times it shoudl feel like pedaling a bike fast -- with a little forward lean (as perpindicular to the ground as you can be) or your hamstrings and back will really suffer -- it is probably a given that your quads will be devastated anyway. Be ready for every muscle in your legs to be like a clenched fist after about 1.5-2mi.
Oh, and enjoy the view. It's spectacular.
