We are hosting a Level 3/4 ICP workshop and are still have openings. We are looking for both Candidate Instructors, and Prelim and above level riders. The dates are August 13-15th in Poolesville MD.
For volunteer riders, there is a day dedicated to each phase, and there will be extensive Prelim and above XC lessons on Thursday. There is free overnight stabling for volunteer riders and no fees for use of the xc course on Thursday (it's all covered by a sponsor!)
