235 Total Finishers (new record)

109 Grizzly Buckle Winners (new record) (24-30 Hours)

2023 Registration is open for our 25th Anniversary!

(UPDATE) – The race filled in 2.5 days and the waitlist grew to 400 by Jan 3rd. It is now over 500. It is unlikely that anyone who registered to join the waitlist after Feb 1 will get in. But, you never know.

The race begins at the mouth of Logan Dry Canyon, on the east bench of Logan, Utah. There are dozens of hotels within ten minutes of the start. Logan is a medium-sized university city with all the amenities you need, including an outdoor/running shop or two. It is less than two hours from the Salt Lake City International Airport.

2023 Race Date/Time: September 29-30, 2023 06:00 Start Time (Friday Start)

Shuttle service from finish to start is $20 per runner (optional for those that don’t have a ride).

All entrants will receive a beautiful tech shirt with a distinctive design. Finishers receive an engraved plaque indicating the date of the event and their finish time and place. They also receive a belt buckle reflective of their time: a Black Bear buckle for times between 30-36 hours, a Grizzly Bear buckle for times between 24-30 hours, and a Wolverine buckle for times under 24 hours.

Example of our 2022 Plaque (Good Job Tom!)

If you run fast enough (Top 3 Male & Female), in addition to the items above, you will receive a small cash prize and a custom-engraved trophy documenting the accomplishment.
