The Run

NOTE: registration for the Spinal Tap Trail 50 Miler has been consolidated with the Crimson Canyon Ultra registration page. Please go to the UltraSignup link below to register:

The Spinal Tap Trail was completed the fall of 2022, and is an 18 mile long downhill mountain bike trail, descending from White Pine Peak (10,200 feet) down to Richfield with a descent gradually dropping 4650 feet over the distance.. This trail is the signature center of the 50 mile distance. It 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 Miles (80km)
Total Vertical Gain: 8510 feet / 2594 meters

Start: 5:00 am (get much of the climbing knocked out early)
End: 11:00 pm (18 hours final cut-off)

7 Aid Stations with a good spread of options.

Required Items: a) Personal hydration for all runners, b) the course map loaded onto a phone or other mapping device. The climb to White Pine Peak (miles 7 to 15) will be in back country areas following cow trails and minimally used human trails. The only course markings in this section will be to assist in the transition from the streambed to the ridgeline. A personal water filter is an option for this section as well.

Routing Details

The different sections of the Spinal Tap Trail are referred to as Upper, Middle, and Lower Spinal Tap (see ). It starts on tippy top of the Pahvant Range just below White Pine Peak, with open meadows, Aspen forests and expansive views. The middle section drops into red rock country, with the trail carved back and forth down and across Little Valley. The lower section has very unique slick rock sections. So you descend through several biomes!.

Here is a YouTube video of the first full descent of the Spinal Tap trail the week it was completed by some of the construction committee members.

Lower Spinal Tap (the bottom 4 miles), which has a good amount of slick rock, has been touted the past several years since it opened, as one of the greatest bike trails ever created in Utah.
