From Endurance Grid
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.
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.
A swim followed by a bike — a triathlon without the run. Sprint and Olympic distances, often alongside a tri at the same venue.
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.
