Big Sky, MT
The Rut takes place on mountain terrain around Big Sky, so expect serious elevation and rugged trails underfoot. This is high-alpine running, not a groomed path through the foothills. The courses push into exposed, rocky ground, and the views from the upper sections reflect how far up you actually are.

The Rut Mountain Runs has been held every year since at least 2013. That is as far back as RunSignup's records for this race go, so it may well be older.

How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Jul 27, 2026.
Set a goal and get a pace band: every mile split on a card sized for your phone lock screen, so race morning needs no math.

Almost certainly not. Half the 6.41 Miles field finished slower than 1:46:47, and the last recorded finisher came in around 7:23:22, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.
With 891 finishers there are runners at every pace, so you are never out on your own. There is no qualifying time, and the finish-time spread above shows how varied the field really is. If it is your first 6.41 Miles, that spread matters more than the winner's time.
The 6.41 Miles winner ran 58:32 while the median finisher took 1:46:47. That spread points to a mixed field, with a competitive front and a big recreational middle.
