100 miles on the same 2-mile Centennial Park loop as the other FRUD distances. Runners may start Thursday at 10:00 AM, Friday at 8:00 AM, or Saturday at 8:00 AM; every distance-based start ends at 2:00 PM Monday.
Front Range Ultra Dayze is a multi-day ultrarunning festival on a 2-mile loop through Centennial Park and the River's Edge Natural Area in Loveland, Colorado. Runners choose from eight events at once: 50k, 100-mile and 200-mile fixed-distance races, and 12-hour, 24-hour, 48-hour, 72-hour and 100-hour fixed-time races, all sharing the same start/finish and the same loop. Runners pick their own start date from a published schedule rather than a single gun time, and free camping is available at the venue for the length of the event.
First held in 2024. The inaugural year also offered a 6-hour race and an out-and-back timing setup that were not carried forward; from 2025 onward the event has run as the eight-distance lineup described above.

These are other people's work and we link straight to them. Watching costs nothing and needs no account. More of them: every race we hold, on film.
Nobody sees it until we have read it. No account, no sign-in.
This changes nothing on the page on its own. Somebody checks it against the race first.
Somebody watches it before it goes anywhere near this page. What we are after is footage of this course, on the ground. If it would be just as true of any other race, it is not this.
We want the address of the file the race publishes, not the file. We download it from there so the page can say where the line came from.
We read every one of these and we write back. Every fact here carries the source it came from, and the way a wrong one gets fixed is a person checking it against what you tell us.
NavRun builds your pacing from your own training, then turns it into a plan your crew can follow: when to leave and where to park.
