Like I said, running messed up my knees/feet pretty badly. I know, not only from playing soccer for 12 years, but also from trying to take 1 mile/8 min. runs in the mornings last semester.
I have a rear rack, and seriously considered bringing it along, but it turns out it's not compatible with the van we're taking.
We'll be sleeping wherever we can (either a friend's place or the van). No hotels, though.
Plyometrics are a good idea, I'll add those to my list.
