Finishing before midnight on Sunday, June 30, 2024, Kyle Curtin brought the men’s supported Colorado Trail fastest known time (FKT) for the east-to-west direction on the Collegiate West variation to a blazing 6 days, 15 hours, and 8 minutes.
Starting on Monday, June 24 at 8:15 a.m., the Durango, Colorado, trail runner set out from the Waterton Canyon trailhead, the eastern terminus of the 490-mile Colorado Trail outside of Denver. Well under 7 days later, he arrived “home” to the Junction Creek trailhead outside of Durango. The Colorado Trail gains something around 90,000 feet of vertical and passes as high as 13,271 feet as it traces through some of Colorado’s biggest and most remote mountain ranges.
The prior record of this specific version of the FKT was set in 2019 by Joe Grant in 8 days, 20 hours, and 9 minutes.
This time also beats the overall men’s supported Colorado Trail FKT, which was set in 2020 by Michael McKnight in 7 days, 13 hours, 16 minutes, and 15 seconds. In McKnight’s effort, he traveled from west to east, and used the Collegiate East variation.
According to Curtin’s GPS tracker and social media, he covered the first 100 miles in roughly 24 hours. By 2 days elapsed, he’d traveled in the vicinity of 175 miles. He surpassed 300 miles some hours before the 4-day mark. He began the final 100 miles somewhere around 5 days and 6 hours into the effort, and covered the final 100 miles in about 1 day and 7 hours.
In total, his pace averages out to 74.5 miles per day, or 3 miles per hour. This includes all stopped time, including to sleep, eat, and otherwise take care of himself.
There are a number of FKTs for the Colorado Trail, depending on the direction and which variation of the trail the athlete takes — either the Collegiate West or Collegiate East. While traversing the Collegiate Peaks area west of Buena Vista, the trail splits for between 70 and 80 miles and trail users can choose which option to take. Traditionally, the Collegiate East version is seen as easier for its lower altitude, less climbing, and shorter distance, and prior fastest times have been set on this variant.
Curtin said on social media that chose the more challenging Collegiate West direction in part because he said it was the trail’s more natural and representative variant of the two.
The Interlaken Fire outside of Twin Lakes caused a local closure of part of both the Collegiate West and Collegiate East variants. The Colorado Trail Association has recommended reroutes for each piece of the trail, and Curtin followed the Collegiate West reroute. This reroute shortens the Collegiate West variant by several miles, but according to Curtin’s social media, it was longer and more difficult than the Collegiate East fire alternate.
On social media, Curtin said he wanted to set a unifying FKT for both variants by taking the harder of the two.
Along the way, he raised over $6,000 for Big City Mountaineers, a U.S. non-profit group seeking to get youth out into the wilderness.
Curtin was supported by an all-star crew of trail runners that included Sarah Ostazewski, Devon Olson, Michael Robertson, Robyn Lesh, Tara Dower, Courtney Dauwalter, Jeff Browning, Maggie Guterl, and others.
