Ultramarathon Races in Missouri

The ultramarathon race calendar in Missouri is busiest in July, October, and December, with races most often in Rogersville and St. Louis.

What an ultramarathon is

An ultramarathon is any running race longer than 26.2 miles. The most common distances are the 50K, 50-mile, 100K, and 100-mile — alongside timed events, where you cover as much ground as you can in a fixed window like 6, 12, or 24 hours.

Many ultras run on trails, with aid stations stocked with food, water, and posted cutoff times. For most entrants the goal is to finish, not to race the clock, and hiking the climbs is a normal part of the day.
