Comlara 12 Hour Sunrise-Sunset, 6 Hour, 3 Hour and Hour of Power Trail Run

This trail run features a "last man/women standing competition" for its longer events. You'll tackle a 4.1 mile course, with one hour to complete each loop. Finish early, and you can relax, refuel, and hydrate before lining up to "run the course again" at the top of the next hour. It's a test of strategic running skills, tactical positioning, and mental toughness. If that's too intense, there are options to "run with the race participants in a low key, non-competitive fashion" for an hour, or even "run the loop completely at your leisure" with "your own defined recovery time per each loop" throughout the day.
