Marathon and 50K Races

Best Trail Festival– Runner’s World Magazine

One of the world’s most scenic half marathons– Active

“This was my first ultra and I was very impressed with the course, organization and event staff.”

“I have [already recommended this race], did by myself the first year, had group of 8 this year!”

“This was the first trail-running half marathon for which I’d signed up and I loved my experience. I plan to do the full marathon next year.”

“Scenery is amazing and it’s a great way to celebrate spring and running season.”

A weekend of fun and running on the beautiful trails near Fruita, Colorado. The weekend kicks off on Friday night with packet pickup and a pasta dinner. Saturday is the trail marathon and 50K, followed that night with a racer party at a local brewery. Sunday’s events include a 10K, half marathon and kid’s races. Sunday’s races did sell out in 2017, so get in early.

In order to be environmentally friendly and cut down on the amount of trash we produce, we will not have cups at the aid stations. So, please carry a water bottle or a collapsible cup on the course.

Racer Dinner

Friday night’s racer dinner is a great way to meet fellow runners and get any questions you might have answered by the Race Director and staff. The dinner will run from 6:30-7:30pm at the Fruita Community Center in Fruita, CO. Details TBA

Kid’s Events

Bring the whole family! This year’s Sunday events will include Kid’s Races at the start/finish area. Kid’s events are free and we will begin registration at 9:30. After we see the ages and how many kids we have we will then decide on age groups and distances (may be as long as .5 miles for the older kids)


The racer party for all racers and the awards ceremony for the Marathon and 50K races will be at 6:30 pm on Saturday TBA. There will be wings and beer! Don’t miss the opportunity to socialize with other racers and win raffle prizes. There will be a $100 cash prize for the women’s and men’s overall winners of the 50K. There will also be $100 cash premiums in the first 2 miles of both days for men and women.

Customized cowbell awards will be given to the top three male and female finishers in each race in each of the following age groups:

under 20





60 and over


Racers will receive customized dog tag finisher’s awards as they cross the finish line. Placer’s awards will be distributed at the awards ceremony Saturday night. Awards and mementos will not be mailed after the event.








Start/Finish Area and Parking

The Start/Finish lines will be at the Mack trailhead on the Kokopelli trail just west of Fruita, Colorado, at exit #11 off I-70. Head South toward the frontage road. The start time for the 50K and Marathon races is Saturday at 7:00 a.m. and the start on Sunday will be at 8:30 am for the half marathon and 10K races. Parking will be very limited and car pooling is strongly recommended. We may need to divert some traffic to an alternate parking lot—please plan to arrive at least one hour prior to your start time to allow time for this, if required. Your race number and packet will also be available at the Start/Finish line beginning at 5:30 a.m. on race day Saturday and 7:00 am on race day Sunday. Sunday’s racers can pick up their packets at Friday night, Saturday morning or Sunday morning packet pick-ups. Packets will not be available after race start on Saturday or Saturday night.


This year’s host hotel will be at the Super 8 in Fruita, CO. Mention the Trail Running Festival for a discount (please let us know if you have any trouble with the hotel and discount).

Weather on the Kokopelli can vary. The averages for April are a low of 35 & a high of 66 degrees.

There will be radio contact available, all necessary materials to nurse any bumps, cuts, bruises, or blisters, a medical tent, and medics. In addition, a certified Emergency Medical Technician will be in attendance. Aid stations will NOT have aspirin, ibuprofen or other NSAIDs.

Local Laws
Federal, State, and County laws and ordinances must be followed at all times.

Staying on Course
Racers must stay on the designated course. Any racer that goes off the designated course (i.e. shortcutting) will result in a disqualification.

Unforeseeable Circumstances
In the case of unforeseeable circumstances due to weather or other extenuating circumstances that prevents the safe continuation of the race, race officials may end the race at any given time. This rule will be implemented in the most extreme cases for the safety of the runners or officials.


These are challenging courses.


The Marathon will be a single loop connecting the desert trails of the Kokopelli and adjacent trails. 50K runners will do an additional 4.6 mile loop beginning at the Moore Fun aid station allowing runners to hit this aid station twice. The courses roll between elevations of 4,500 and 5,400 feet with over 3,400 feet of climbing.

Start: A nice warm up takes runners out one mile of gently rolling dirt road. A .3 mile uphill brings racers to an open area where there will be a water drop and a course official will be waiting with a $100 cash premium for the first male and the first female to reach this point. A sharp left turn puts runners on the first single track of the day. Once on this section, it will be difficult to pass so find your place before your reach this section. Large rocks and twists bring you to a high point where you will stay close to the edge and enjoy beautiful views before the rugged descent down the other side.

50K Out and Back: After leaving the aid station, runners will head down the road to Rustler’s Loop. Traveling clockwise around the loop, this soft dirt trail winds its way through gently rolling hills and wide open fields. After completing the loop, the course brings you back to the Moore Fun aid station.

Moore Fun: A short downhill will bring you to a rugged jeep road. It will take you up a gentle climb and descent until it dead ends into the wide, flat and fast section of Mary’s Loop. Head right on Mary’s Loop, going through some fun technical terrain with amazing views of the Colorado River, to reach the Pizza Overlook aid station.

Pizza Overlook: Upon leaving the aid station, you will immediately begin descending quickly. A narrow trail and big drop offs will eventually open up as you begin following the rim in and out of the canyons. On an incredibly picturesque course, this section is generally considered the most beautiful.

Crossroads: After a short climb, the course passes some intersecting trails and makes a couple of sharp turns (be sure to pay attention to the course markings). This will lead to the undulating, remote section of the Troybuilt Trail. This is the longest section between aid stations so be sure to carry water with you. A fun descent through a wash will bring you to the aid station.

Troybuilt: Leaving this aid station will put you on the steep, hot climb of the day. Eventually bringing you to Mack Ridge, this section will open up, once again following what some would consider a little too close to the overlook. A steep descent will bring you down to the water drop and back onto the road toward the finish line.

Sunday Course:

Sunday’s Half Marathon and 10K races start together.

Start: Runners head out the gently rolling dirt road for a mile until they take a sharp right turn for .3 miles to the top of the hill. From there, the first aid station is visible and racers cross the cattle guard, staying on the road, and head down the steep hill to the Crossroads aid station.

Crossroads #1: Both distances will head out from the aid station and head down the steep, rocky gully for a short distance until it flattens out but continues twisting and turning. Runners will reach a “T” in the road where they take a left hand turn.

Runners will follow along the beautiful rim for a short time before they head up the steep ledgy section to the Pizza Overlook aid station.

Pizza Overlook (10K): 10K racers will take a left at the aid station on the rugged jeep road back to the Crossroads aid station #2, back over the cattle guard and to the finish line.
(Half Marathon): Half marathoners will travel on the open rolling section of Mary’s Loop until they hit the Wrangler’s Loop cutoff. They will make a sharp left where some sections will be loose or sandy but overall good footing. A nice decent will bring racers to the Moore Fun aid station.

Moore Fun: The trail becomes rocky and technical as it makes the big climb to the top of this fun section. After it levels off for a short distance, it will make a fun technical decent to the cattleguard and a water drop that you visited on the way out. From there, you will go back the same way you came, down the short steep section to the dirt road and back to the finish.

Aid Stations

For environmental reasons cups will not be provided at the aid stations. Aid stations will NOT have aspirin, ibuprofen or other NSAIDs.
