2018 entries will open at midnight on January 1, 2018 (specifically: that is as the clock strikes 12:00 on New Year's Eve, December 31, 2017). Entry fee is $150, plus applicable UltraSignUp fees. For the 2018 event, a runner who drops out and advises Race Director of such by February 28, 2018 will be entitled to a full refund. No refunds or roll-overs past that date. NOTE: The race has traditionally sold out anywhere from within 24 hours up to 2 weeks, so anyone wishing to enter is advised to act quickly. ALSO NOTE: Race is subject to permitting by the U.S. Forest Service, which may, at its sole discretion, deny or cancel their permit at any time. If such an event occurs, race management will make best efforts to refund all or at least some portion of entry fees. However, a refund of all or any portion of entry fees is not guaranteed.
You can register at UltraSignup. Registration price is $150.
