Prescott Monstercross


At 7:30 am on Sunday, April 16, 2017

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!

There will be two route options again this year! GPX files are posted below. This free ride is limited to the first 74 people that sign up.

Shorter route (miniMonster): 60 miles with ~7,500′ of climbing. A lot has changed for 2016 as trails continue to be built all around Prescott. This loop is now essentially the Circle Trail with deviations into the Granite Dells and Granite Basin for good measure. Anticipated completion times for this loop will be 6-9 hours.

Longer route (megaMonster): 72 miles with ~12,000′ of climbing, showcasing the both variety and difficulty of the riding Prescott has to offer. While only 12 miles longer than the miniMonster, this route is MUCH, MUCH tougher. Do not underestimate it! This route will let you explore the western side of the Sierra Prieta and test your climbing legs, both on and off the bike. This longer route will no longer use 299, Smith Ravine, and 305 at the end. Anticipated completion times for most riders will be 9-12 hours.

Here are what the routes and profiles look like for 2016.


GPX files:

Updated route files will be available for download a week prior to the ride. Prescott’s trail network is steadily evolving, so this year’s routes will be slightly different. There still will be a ~50 and a ~70-mile option.



In the past, we’ve had cues, but they are a lot of work to make. For this year, use the GPX files above and the City of Prescott trails map, available here or at any bike shop in town for a mere $1. If you don’t have a GPS, ride with someone who does for the first half of the miniMonster. The miniMonster follows the mostly-well-marked Circle Trail after the first half of the ride, so beyond Granite Basin (~mile 30), all you really need is the trail map.

Water: There is water available at a few places along the course, and usually, these are all turned on by the beginning of April:

(1) Mile 14: Just off the route at Willow Lake after emerging from the Dells. Look for the brick bathroom building to the north. With the revision of the route around the Dells, this is slightly off-route.

(2) Mile 18: At the ballfields. Aim for the main building with bathrooms. There’s a fountain outside.

(3) Mile 28: Spigot at Cayuse Trailhead. This was already on as of 3/19/16. Fill up here…it’s the last water on course unless you want to drop a mile or so back into town on White Spar Road to fill up.

(4) NOTE…this spigot will NOT be turned on! Mile 47 (mini)/59 (mega): Spigot in White Spar Campground next to the bathrooms.

(5) NOTE…this stream was already dry on 3/20/16! For the mega, there’s a small stream at mile 40. A lot of riders have run out of water between here and White Spar CG in the past, so it is strongly recommended that you treat some water from this stream! But there are cows about, so don’t just dunk your bottle and drink!

  1. Hey Kurt, April 15th is the same date as MBAA Prescott Punisher. I know several riders that would like to do the AES ride but are committed to the MBAA circuit b/c of sponsorship/team. Any chance we could move that to 8th or 22nd ?

  2. Thanks Chad. Now if only my wife will let me ride on Easter Sunday.

  3. Being in Easter makes it a no go for me. Hopefully it’ll be back to normal next year.

  4. Dang, I apparently don’t have holidays showing up on my calendar. Would Sunday April 2nd work any better for folks? There seem to be more events in April than normal to schedule around this year.

  5. April 2nd works for me, day after SBFL. Weekend of AES events !

  6. Is this event still on schedule?

  7. This event most certainly is still on the calendar. It’s going to stick to Easter Sunday. That works for most folks to whom I’ve talked.

  8. For those who don’t want to do Easter Sunday, I propose we do it Saturday April 15th. Same time, same place. ITT style. We will need to watch the MBAA site and avoid their race traffic.

  9. When is registration going to open up for 2017?

  10. I’m in!

  11. The GPX you have for the Mega Monster route is only a 3 miles section. do you have the full mega route?

  12. Make sure to use the registration above also if you are new to AES.

  13. Hey why not just hide eggs along the course and make it an Easter egg hunt.
    Raw eggs and the one who gets the most to finish unbroken wins. Dang now I have to race mbaa Saturday and PMC sunday

  14. I’m in.
    While it’s pretty early in the ride the Peavine Trailhead always has water. If the fountain’s off just use the sink in the restroom.
