About the Route:

Map A few days before the 2015 Bailey HUNDO, Race Director, Austin Smart, was faced with a decision that would forever change the Bailey HUNDO. Heavy rains hit the area causing the South Platte River to swell to the point that the bridge and river crossing at the beginning of Segment 2 of the Colorado Trail were impassable. Without riders being able to access the road to Deckers, the traditional route up and over Stoney Pass would be impossible.

The decision was made to hold the race with two laps on the HUNDitO course. Riders responded to the course change with enthusiasm. Many appreciated the additional singletrack as well as the race taking place entirely within the Buffalo Creek Trail System. The only issue with this course was its length. Coming in at 83 miles with 9,500’ of climbing, the course had to evolve.

A new iteration was presented in 2016 as the course committee aimed to give riders what they desired: singletrack. Therefore, the goal was to provide a 100+ mile course that showcased even more trails within the Buffalo Creek Trail System. The course was extremely difficult and riders commented that it was one of the most challenging races of the season (107.6 miles with 13,200 feet). The demanding course was accompanied by extreme heat forcing many riders to abandon the race.

After reflecting on rider feedback from 2015 and 2016, the course committee has spent the past 6 months at the drawing board creating a new HUNDO and HUNDito course that we believe everyone will love. – See you on June 17, 2017!!

HUNDO: 90 miles. Approximate Elevation Gain: 10,200 feet
HUNDitO: 50 miles. Approximate Elevation Gain: 5,800 feet

NUENUE Marathon Series


The HUNDitO race is part of the newly created NUE Marathon Series! Similar to the 100 mile series, a rider’s four best finishes will be used to determine placement in the NUE Marathon Series. Award categories are the four NUE Series Categories (Open Men, Open Women, Open Singlespeed or Masters 50+).

Finish Area Meadow / Camping

Racers are encouraged to arrive at 2pm Friday and camp the evening before (and after *) the race. This meadow is a private gem nestled between rugged mountains, carpeted with lush grass and wildflowers with a beautiful clear running stream, drinking water provided, lots of parking, campsites and is walking distance across a log pedestrian bridge to the finish line, the venue for the Friday evening pasta feed, post race meal and festivities. We encourage reasonable size vehicles, but absolutely no campers longer than 22 feet. There is a strict NO DOGS policy in the finish meadow – thanks in advance for leaving your furry friend at home.
* Our Park County permit allows limited number of campers on Saturday. To reserve a place please contact race director Austin Smart.
