Spinal Tap Trail 50 Miler (Crimson Canyons)

Richfield, UT Spinal Tap 50 Miler

Registration closes: Wed, Sep 13 @ 11:59 PM

New for 2023!

Come experience the newest, very challenging, 50 mile race in Utah! The Spinal Tap 50 Miler is held in conjunction with the Crimson Canyons Ultra races. Parts of this race are on the amazing Pahvant Mountain Bike Trail System, and parts will be through primitive streambeds, ridgelines, and remote ATV trails. The signature center of this race is the newly completed Spinal Tap mountain bike trail, which is 18 miles all downhill, gradually dropping 4650 feet. This trail took a dedicated crew of engineers and workers three years (2020-2022) to build.

Before starting the Spinal Tap downhill trail, runners will first climb to the summit of White Pine Peak, at an elevation of 10,200 feet (3110 meters). Getting there will be a primitive adventure challenge, with about a 4 mile climb on cow paths along Willow Creek (South Fork) and then another 4 miles up a wide non-technical ridgeline.

Some Details

Total Distance: 50.7 miles / 81.6 km
Total Vert: 8587 feet / 2716 meters

Start: 4:00 am (get much of the climbing knocked out early)
