The original Bear Chase distance — four loops on Denver's fastest singletrack
Other trail races within 31 miles
The original Bear Chase distance, born from RD David Manthey's long training runs through Bear Creek Lake Park. Four loops of the 12.5-mile Orange Course deliver a fast, non-technical 50-miler on smooth singletrack with sweeping views of the Front Range. With crew access at the Start/Finish every 12.5 miles and a 15-hour cutoff, this is an ideal race for runners seeking their first 50-mile finish or chasing a PR on a forgiving course.
