The Firebird
A Colorado end-of-summer outdoor celebration! Come celebrate the beginning of fall in the mountains with a mountain bike challenge! An exciting weekend of festival fun and adventure on the trails near Eagle, Colorado. With the start/finish line right in the heart of Eagle friends and family can enjoy themselves while you ride this rugged mountain race. Enjoy a weekend of relaxing with a beer, hot meal, music and a massage at the recovery station. Join the runners at the Saturday night party!
Experience uphill grinds and beautiful singletrack. Both the 50K and 30K courses are a great test of stamina and give a culmination of summer training. With the combination of many short ups and downs and a couple big climbs, this event will definitely test your fitness. Racers will have three aid stations (two for the 30K) and will receive a finisher’s memento and age group awards.

A portion of the proceeds will benefit The Cycle Effect, a local non-profit with the mission to empower girls through mountain biking.
Our packet pickup and start/finish area will be well provided for by our incredible sponsor – Color Roasters.
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. Please carry a water bottle on the course.

Our host hotel for the weekend events will be announced soon. There will be group discounts!

The Firebird 50K & 30K races start in the heart of Eagle, next to Color Roasters. Racers begin by riding 2 miles on the bike path along Eagle Ranch Road and Haystacker Drive, where a right turn onto the Turniphead Trail marks the start of dirt miles until the finish.
Just shy of a mile after turning onto dirt, riders pass through the Arroyo trailhead, at mile 2.4. From Arroyo, the course continues steadily up, first on double track on Third Gulch Trail, then veering left onto singletrack on Pipeline Trail. Throughout this climb, riders travel from sage-covered high desert into beautiful aspen groves on the Pipeline Trail. 1300 vertical feet above Arroyo riders reach aid station #1, Firebox, at mile 6.5.
Racers leave the aid station and continue uphill on Hardscrabble Road briefly to a hard right turn onto the Firebox Road hike a bike . After 2 miles with some steep climbs through forest and pastureland on Firebox Road, riders veer left onto singletrack and descend to toward Dead Cow.
A very steep but short hike-a-bike awaits riders as they leave the aid station onto Mike’s Night Out. The course rewards with sweeping views as it continues on Mike’s Night Out bombing down on beautiful singletrack to aid station #2, Spring Creek, at mile 13.0. A short and beautiful ride on Itch will take you to the World’s Greatest downhill much of which is fast and flowy and some is just steep.
From here, 30K riders will exit to the finish while 50K riders continue into the course and begin the climb back into the mountains.
After a sharp left turn at the Schoolhouse trail the course brings you back up to the Spring Creek aid station through Star Wars and Easy Rider. After Reaching Spring Creek #2 riders once again get to experience World’s Greatest.
From here, the fun isn’t quite over, as the course heads up one final 200-foot climb. From the top of this punchy climb, the trail makes a serpentine descent to the Horton Street Trailhead. Riders head down the neighborhood street and turn left onto the bike path. A short 0.4 miles along this path lead to the finish line and after party at Color Coffee Roasters.
