About These Sports
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.
Running
From 5K to marathon, running races are the most accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
Trail Running
Running off-road — dirt, singletrack, and mountain paths — from 5Ks to ultras. The terrain, not the pace, is the whole point.
