Mid Mountain 50K

Date
Aug 15 2026
Distance
50K
Elevation
Deer Valley → Utah Olympic Park

50K across ridgelines most people only see from a chairlift. The course opens with a loop at Deer Valley, then runs nearly 20 miles of the iconic Mid Mountain Trail to its terminus. One last uphill push, then a long winding descent through the Olympic Park trail system. It does not care that you watched this video. It cares whether you showed up.
