Trekking poles allowed. No Teams. No Whining. Route will be well marked. Free Will Donation Registration Fee | In lieu of a registration fee, entrants will pledge funds that will be split between the winning runners’ charities. Tax Deductible Donations/Pledges need to be complete by using this link through our fiscal sponsor Falls Area Singletrack –TutHell — Falls Area Singletrack (FAST) on the TutHell50k.com website.
