ulterior motive: make sure the new bike rack works before we drive all the way to illinois..
Go get 'em! For that race, pump those tires up to max psi, imho.
I agree. All paved and hard packed gravel roads, and they may have you bike back into the area behind the camp, but that's hard pack trail. This is a race where if you are a fast biker, you can make up a lot of time. The orienteering is fun too. Lot's of interesting terrain. You two will ace the climbing sections! Good luck :)
also if prone to blisters, desitin or otherwise can be wise, since you'll be crossing the that river in the camp one way or another.
