This race spans more than one sport — here’s a guide to each, so you can understand what’s involved and decide if it’s the right fit. For course distances, logistics, and race-day specifics, always defer to the race organizer’s event page.
An ultramarathon is anything beyond the standard marathon — 50K, 50-mile, 100K, 100-mile, and timed events. Crossing the line is less about speed and more about not quitting.
From 5K to marathon, running races are an accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
