The Four Seasons of Horsetooth Mountain Bike Challenge is a grass-roots un-event with no entry fees and no real start times and is ridden on the two solstices and two equinoxes in Horsetooth Mountain Park and Lory State Park. By being required to complete at least three seasonal stages, we hope it encourages you to come ride if your schedule doesn’t permit on any given stage. The course is designed to offer what we think are the best sections of trail in our backyard. The course should take about 2-3 hours. Had fun in the winter? Bring a friend for the spring stage! Don’t own a fancy team kit or 20lb race bike? Neither do we! Come ride for the fun and challenge of completing all four events! Check out the rules in the link below.

  • Winter – December 20-23, 2019
  • Spring – March 20-23, 2020

Grand Enduro

The Grand Enduro will challenge you on three demanding stages in and around Grand Junction’s Lunch Loops trail system. For those unfamiliar, the nature of these trails is very technical and require expert handling skills as well as solid fitness.

What to expect:

  • Chunky, desert terrain that’s hard on body and equipment – bring sturdy tires and spare tubes!

  • Stages will lose significant elevation, but lack sustained steeps – be ready to pedal! However, this is no XC race, so bring your well equipped all-mountain bike. You’ll hate it on some of the punchy, short climbs but wish you were on an even bigger bike at some points!

  • All stages feature at least a few “moves” – sections of trail that are particularly precarious. Where possible we’ll have go-arounds, however these will generally cost you time! Pre-riding all stages is definitely recommended and required for stages 1 and 3.

  • 25-40 minutes of racing over 7.2 miles of trail. 2.5-4 hours of total ride time covering ~23 miles.

The Kokopelli Trail was built in 1989 by COPMOBA, a small group of committed bikers who envisioned a single contiguous trail stretching from Colorado to Moab, Utah. It was named for Kokopelli, the magical flute player who wandered the desert and was able to drive back winter according to Hopi legend.

Bikerpelli is a series of two identical annual trips in late April/early May travelling the trail in a unique, intense style we’ve refined since 2002, and represents what we believe is the best way for an experienced biker to enjoy the entire trail in a realistic time frame. The idea is simple – we handle all the details & leave you free to ride for 4 days without having to worry about logistics, camps, meals or emergencies. Just show up with a bike, a tent & your toothbrush & we’ll handle the rest.

Without any additional loops, the Kokopelli Trail covers 142 miles total and limited to the first 90 registrants. The route has evolved thru the years to include several addt’l sections of unforgettable riding, and a couple pieces are commonly skipped for being less fun. We have all the inside info on this & our trips are built with rider’s experience in mind.

Rating the trail’s difficulty is a challenge as the terrain can vary widely from serene, meandering 2wd roads to steep, rocky & technical pieces best hiked thru. 95% of the trail is completely ridable by a strong-intermediate rider with average technical skills and a solid base of endurance training.

Still, this is considered a strong-intermediate to advanced ride and is not recommended for beginners.

Iron Horse Bicycle Classic

Brothers Tom and Jim Mayer concocted the idea behind the first Iron Horse Bicycle Classic. Jim worked as a brakeman on the Denver & Rio Grande Western Railroad, which had operated the steam-powered line between Durango and Silverton since the 1880s. Tom was a young bicycling enthusiast who enjoyed riding alongside the railroad tracks.

One day in 1971, Tom challenged his older brother to a race to Silverton. Steam engine versus bicycle. They wagered a candy bar on the results.

When Jim pulled into the Silverton station, there was Tom, waiting for him. He’d beaten the train, despite having a longer road and having to climb two mountain passes. He won his candy bar, alright, and he had no idea that he had just started a famous race that would draw thousands of riders to southwest Colorado.

You can read more about the story of the Iron Horse by visiting Tom Mayer’s website here:

Superior Morgul Weekend

Two of the most iconic course on back to back days, right in the heart of Boulder County!

Superior Morgul Time-Trial – May 16th
Superior Morgul Road Race – May 17th

On Saturday the action kicks off with the eight mile time trial event down Marshall rd & Cherryvale, with the added bonus of a team-time trial event on the same course. The action continue with Sunday’s road race! The Morgul Bismark race this year will once again feature the closed course used in 2016. This highly spectator friendly version of the course takes athletes up and down the “infamous WALL”, while eliminating the highway 93 and Marshall rd section (see course map for more details)

The Original Growler

  • Saturday May 23, 2020, The Half-Growler, around 32-miles on the dirt* (limited to 350 riders)
  • Sunday May 24, 2020, The Full-Growler, around 64-miles on the dirt*
  • Sunday May 24, 2020, Sunday’s Half Growler, around 32-miles on the dirt* (Sunday starters limited to 350 riders)

For the 2020 Growler, we have introduced a new team category for the main event. Two-person teams compete on the same course as the Full-Growler, with each rider racing one 32-mile lap at a time. The rider who starts the race from downtown Gunnison will tag their teammate at the Hartman Rocks base area after they have finished their 32-mile lap, where the second rider will then take off. The teammates combined lap times will determine their overall standing, with three team categories: Women, Men and Co-ed. The team category is great for those that want to experience the Growler, but prefer racing with a buddy.


We have shuffled the course deck and added the new Graceland trails and a new section of Skyline (both of which your entry fees helped to build), losing the Powerlines Road and the pavement of Gold Basin Road. Apologies, but this change up just added more techy singletrack! Check out the new map HERE.


New Half Growler and (Sunday’s Half Growler, too) categories for young riders based on grade in school (as of fall 2020): 8th graders and younger; high school freshman and sophomores; high school juniors and seniors. We also have Collegiate and the all new CLYDESDALE category for both the Full and Half Growler.


ORIGINAL GROWLER KID’S RACES will take place on spectator, family friendly multi-lap courses at the Hartman Rocks base area on Saturday, May 23. While this event is free, we’ll still need you to stop by and sign a waiver before participating. Please visit the “KIDS RACE PAGE” for all the juicy details!

For ten years, the Original Growler has not wavered from our guiding principal of asking you to trade your hard earned dollars for three things:

  1. An awesome day on the bike. The Growler offers a challenging, singletrack heavy mountain biking experience on some of the finest trails on the planet.
  2. A killer party. Food, drink and camaraderie, post race, in downtown Gunnison (for those that still have some party left in them!)
  3. Top shelf trails, both existing and developing. Regardless of where you live, you become a stakeholder in Gunnison area trails as every penny of your entry fee goes directly to the 501c3 not for profit, Gunnison Trails, and Gunnison Trails’ mission is focused solely on improving and expanding area trails.

The Original Growler showcases most of the trails at the Hartman Rocks recreation area on BLM public lands. “Hartman’s,” as we call it, was chosen as one of the top 20 mountain biking destinations on BLM lands and offers a one-of-kind trail riding experience. If you have ridden Hartman’s, you know all about the magic of these high desert trails.

If you haven’t, you owe it to yourself as an experienced mountain biker to test your skills and fitness on the trails at Hartman Rocks. You’ll be forced to alternate relentlessly between fast and flow in seas of sagebrush and tricky and technical through weathered and twisted juniper on islands of granite and in the many micro canyons that pock this primal landscape. While there are no big climbs and the total vertical gain isn’t remarkable, the seesaw nature of the Growler course is a supreme test of all around mountain biking. Go ahead, commit. But be prepared to challenge your mind, your body and your skills.


Grand Junction Off-Road

All participants will climb their way out of downtown Grand Junction onto the Uncompahgre Plateau, while connecting some of the area’s favorite technically challenging singletrack, double track, gravel roads and the occasional paved segment in the world famous Lunch Loops trail system and beyond.

During your visit to Grand Junction, enjoy three days of festivities in the Downtown Music Festival while being submerged in the mountain bike industry. Mingle with bike-minded people and the Grand Junction community while enjoying the area’s wine country and its appreciation for the outdoor enthusiast.

Bonus: All Finishers receive an engraved stemless wineglass emblazoned with the distance they’ve finished, 3-days of outstanding free live music, a cold beverage (gratis) from Four Peaks Brewing Company, and the comfort of its meandering main street engulfed by industry expo + beer garden waiting at the finish for all Off-Road participants…this is one finish line worth achieving.

The ‘Grand’ has a 95% finish rate. Technical? Yes. But attainable, too.
