Sports guides give you a brief introduction to a sport, what race day is like, and what you need to get started.

Swim, bike, run — back to back. The sprint distance makes it far more accessible than most people think. Three sports in one race means three movements to train and race day never gets monotonous.
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.
Gran fondo, century rides, and road races. Built around sustained effort and pacing judgment — as much a mental sport as a physical one over long distances.
Open water races from 1 mile to marathon distance. No bike, no run — just you, the water, and whatever you've got left.
Run, bike, run. The multi-sport format without the swim. Two disciplines, one race — a great bridge between running and triathlon.
Running off-road — dirt, singletrack, and mountain paths — from 5Ks to ultras. The terrain, not the pace, is the whole point.
Anything beyond the marathon — 50K, 50-mile, 100K, 100-mile, and timed events. Aid stations, cutoffs, and finishing as the goal.
A swim followed by a bike — a triathlon without the run. Sprint and Olympic distances, often alongside a tri at the same venue.
A continuous race alternating open-water swimming and running across a series of segments. Distances and legs vary by event.
Off-road cycling on mixed terrain — pavement, gravel, dirt — for miles. More adventure than road racing, more accessible than mountain biking.
Mud, obstacles, and miles. Spartan Race, Tough Mudder, and the toughest courses out there. Raw fitness meets mental grit in a way no other sport matches.
XC races, enduros, and fat bike events across the best trails. Technical, physical, and completely different from anything on pavement.
Covering a distance on foot under a weighted rucksack — from timed solo challenges to longer team events.
Trek, mountain bike, and paddle with navigation between checkpoints — from a few hours to multi-day expeditions, usually in teams.
Kayak, canoe, SUP, and outrigger races on rivers, lakes, and ocean. Sprints to marathon distances, split by craft.
