After some research yesterday, I was only able to find that Pete Thorndike has confirmed lane space at Copper Wed - Fri leading up to USASA Nationals. Though Chris Klug has a camp at the same time, it is in Aspen. I really like the idea of training on the same runs, same elevation as the races.
Saturday is open practice for all competitors and the events start on Sunday. So by attending Pete's camp you can get Wed - Saturday training leading up to the event. I have also put in a call to Matt at Eldora to see if they will be training that weekend.....which might also give us a training opportunity for Sunday.
Please send me an email if you are interested in training pre-Nationals and I can walk you through all the different alternatives I have found....maybe there are more ideas I have not yet uncovered.
