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.
Duathlon
Run, bike, run. The multi-sport format without the swim. Two disciplines, one race — a great bridge between running and triathlon.
Running
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.
Open Water Swimming
Open water races take place in lakes, rivers, bays, and oceans. Distances can run anywhere from a short 500m swim to 10K marathon events. Just you and the water.
Triathlon
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.
