Prescott Monstercross


At 8:00 am on Saturday, April 20, 2019

Meet just east of Prescott at the Frontier Village parking lot on State Route 69. Look for Harbor Freight Tool, and please park toward the west end of the shopping center well away from the stores. There are many more post-race food and drink options here than at the old meeting location, including a Subway owned by local mountain bikers!

Prescott Monstercross is an annual Spring ride around Prescott’s world-class trail system. And the route has evolved yet again for 2018! Again this year we have a shorter and longer options showcasing the Prescott Basin’s best singletrack, the diverse scenery, the slickrock, the ridgelines, more new trails, and just a little bit of Bradshaw chunk for good measure. The short loop this year is a bit more demanding than in past years, and the long loop is less demanding than the megaMonster from the past few years.

The basic details:

“Short” Loop

  • 62 miles of mostly singletrack – many of the miles are fast and flowy
  • 8,000 feet of climbing
  • Expect the ride to take between 5.5 and 9 hours
  • Water is available at the Willow Lake Dells boat launch, the Cayuse Trailhead in Granite Basin, and White Spar Campground (assuming the spigots have all been turned on for the season). Water is also available slightly off-route at the Thumb Butte Trailhead. Download the waypoints file for the locations of these water sources.

“Long” Loop

  • 75 miles of mostly singletrack – adds in some chunky trails higher in the Bradshaws (but this does NOT drop way off the west side of the range like in past years)
  • 11,000 feet of climbing
  • Expect the ride to take between 7.5 and 11 hours
  • Water is available at the Willow Lake Dells boat launch, the Cayuse Trailhead in Granite Basin, White Spar Campground, and Lynx Lake Campground (assuming the spigots have all been turned on for the season). Water is also available slightly off-route at the Thumb Butte Trailhead. Download the waypoints file for the locations of these water sources.
  • The Lynx Lake Store near the end of the route can supply calories for the last climb if you’ve bonked!
