Suttle Lake Trailfest
Suttle Lake Trailfest on October 24, 2026 in Sisters, Oregon features timed trail events in three formats. The event is organized by Alpine Running and takes place on a looped trail around Suttle Lake.
- 24 Hour event
- 12 Hour event
- 6 Hour event
The course is a 3.6 mile loop with about 110 feet of elevation gain per loop. The trail is described as well maintained and non-technical, with a soft forest floor and some exposed roots. One aid station is located at the start and finish area and will offer sweet and salty snacks, water, soda, electrolyte drink, gels, and warm food items. Participants may set up a personal aid station nearby. Total mileage is recorded at the completion of each loop.
Additional on-site provisions include free camping at South Shore Campground and a warming tent. Pacers are allowed at the halfway point after set elapsed times: 12 hours for the 24 Hour event, 6 hours for the 12 Hour event, and 3 hours for the 6 Hour event.
Registration closes on Thu, Oct 22. The refund policy does not allow transfers. Cancellations more than 30 days before the race may receive a 50 percent credit toward the same event the following year. Cancellations 30 days or less before the race receive no credit or refund. If the organizer must cancel a race and it cannot be feasibly rescheduled, refunds or credits will not be given. Registration fees support a race beneficiary.
