Requests for cancellation and refund should be submitted by no later than May 15th. The refund amount will be the original registration fee, minus a $30 administrative fee. As an alternative to refund, a registrant may request a "one year only" carry over of their registration. This option would ensure the registrants entry within the allocated 400 person limit for the following year. Requests for registration carry over must also be submitted by no later than May 15th. Carry over registrations not used the following year will be forfeited. Refunds will not be issued for carry over registrations.

In general, refunds and carry over registrations will not be issued after May 15th. Limited exceptions, such as verified sudden family emergencies/bereavements and military activation will be considered on a case-by-case basis by the Race Director.

RACE REGISTRATIONS ARE NOT TRANSFERRABLE AND MAY NOT BE SOLD OR BARTERER IN ANY WAY. Runners may be required to provide valid I.D. at registration check-in.

The Tahoe Rim Trail 50K/50M/100M Endurance Runs is a beneficiary event with all net proceeds donated equally between to the Tahoe Rim Trail Association’s trail maintenance program, the Lake Tahoe Nevada State Park’s backcountry mountain bike patrol and other supportive organizations. The Sagebrush Stompers and Tahoe Mountain Milers Running Clubs are both 501(c)(3) non-profit organizations. We do not make any profit from this event.

All supplies, food product, clothing items, awards, signs and other items that are not part of a sponsorship contribution are purchased prior to the event in numbers adequate to accommodate the total number of possible registrants. If unlimited refunds were issued they would result in either a direct loss to our clubs’ coffers and/or would reduce the final contribution to our beneficiaries. In addition, we would end up with products and perishable items we would not be able to get refunds ourselves.

PLEASE NOTE: The Tahoe Rim Trail Endurance Runs have filled early the past four years and many interested runners were placed on the event's waiting list in hope they would be able to run. Out of courtesy to your fellow runners PLEASE let us know in advance if you are not able to attend so others can fill the vacant slot. Registered runners who DNS (do not show) AND DNC (do not call) without valid, acceptable excuse MAY risk not being able to participate the follwing year.

We sincerely hope you understand our decision.
