A marathon is a 26.2-mile (42.2 km) running race — the classic endurance event. An ultra marathon is any race longer than marathon distance, typically 50K, 50 miles, 100K, or 100 miles, often on trails. A triathlon combines swimming, cycling, and running in a single event, with distances ranging from sprint (750m swim, 20K bike, 5K run) to full IRONMAN (2.4 mile swim, 112 mile bike, 26.2 mile run). EnduranceFinder helps you find the right event for your goals.

EnduranceFinder connects you directly to official event registration. Click any event listing to view full details — including course maps, cutoff times, entry fees, and registration deadlines — then click "Register" to be taken directly to the race's official registration page. We never add middleman fees or markups. Registration goes directly to the race organizer.
