About this race

We are excited to announce the 4th Annual Swift Bear Trail Run along with the new added event of 50K! It will be held Saturday, August 8, 2026 during Hays Powwow in the beautiful Mission Canyon. Along with the 50K, there will still be the 10 Mile and 20 Mile runs. So, come on out and get your run on!

The 20 Mile run is a loop in the mountains that consists of 2 track roads, gravel, and approximately 3 miles of pavement.

***IMPORTANT 20 MILE INFO - If you expect your overall completion time to be more than 6 hours, we ask you to move your start time to 5:30 am with the 50K runners. 

***IMPORTANT 50K INFO - There will be a cutoff time for this race. If a runner has not made it to the last aid station (approximately 10 miles from finish line) by the 8.5 hour mark (1:30 PM) this will result in a disqualification. 

Like last year, there will be prizes given to the top male and female finishers in both the 10 and 20 Mile runs. Prizes for the 50K are TBD at this time. 

All runs start and end on the east end of the powwow grounds; look for the white canopy and check-in table. Runners will meet 30 minutes before start of each run at the starting line. 

Stay tuned to our Facebook (https://www.facebook.com/profile.php?id=100093653076456) for more details! We look forward to seeing you!
