With the Whiteface Mountain Uphill Bike Race the day prior, it's sure to be a fun mountain bike weekend in the Adirondacks.

Please remember that the Town of Wilmington, ADKSC, and the entire local community do a lot of work to prepare the course and offer a first-class racing experience. We thank you for being courteous and doing your part to keep the venue and the Adirondacks clean.

Course cutoffs
3 p.m. Official Finish Time
You must complete the 100K race in less than eight hours. Our desire is to see everyone finish, and we will support you the best we can. However, if we do need to remove someone for missing the cutoff, the decision of the race official is final.
Racers who are registered for the 100K distance will NOT be allowed to change and compete in the 50K distance once the race begins. This will be an automatic DQ.
If you are registered for the 100K and wish to change to the 50K, see Ken at the packet pickup area to switch the day prior to the race. Please know we are unable to provide a refund for the difference in price.
