2021 Entry Fees

All entry fees are non-refundable and non-transferable.

  • Early registration fees (by October 31st) are $100 for 80 mile, $160 for 160 mile
  • Late registration fees (after Nov 1st) are $150 for 80 mile and $210 for 160 mile

This year we are charging $35 of the total entry fee at the time of initial registration which opens on August 1st. We will then ask you to pay the balance once we are fully confident of holding the event. We are doing everything we can to make this event happen in 2021 but given the uncertainties around Covid we are delaying the full entry fee payment.
