Catfish Flats

Catfish Flats is a set of community-run races held on 02/20/2027 at the Catfish Flats parking lot in Chatfield State Park, Littleton, CO. The event offers multiple measured road distances and is listed as free entry.

Available distances:

  • 5K (3.10 miles)
  • 10K (6.20 miles)
  • 15.5K (9.60 miles)

Registration for the event closes on Sat, Feb 20 at 9:00 AM Mountain Time (MT). A new bib is required for each race entered this year. Runners with dogs start separately to reduce interactions with other runners. Check-in occurs before the races.

The organizer states races are not canceled; if weather forces a physical cancellation, the event will be held virtually and submitted results are due one week later. Virtual entry is not offered except when weather cancels the in-person race. Course records for all races and distances are listed on the RRC website.

Start and finish for the Catfish Flats race are at the Catfish Flats parking lot in Chatfield State Park. Visit the organization's website for the most recent information.
