The Millerton Lake Sprint Triathlon has long been known as a great "first lake swim" triathlon, and a warm up for the upcoming season. But don't let the bike and run distances fool you, there are a few steep hills on the ride, and the trail portion of run is a challenge.
More of a good thing... The Olympic Distance has a more challenging swim, two loops of the bike course, and two loops of the run course with a trail run heading out, a paved road coming back and beautiful Millerton Lake as the backdrop.
Note:
A USAT membership is required for the Triathlon, (but not the 5k/10k) If you do not have one, you can purchase one during the registration process. Per USAT rules, multisport participants must present ID and USAT membership card at packet pickup.
Total participation at this event is capped at 200. Register before it is sold out.
There is a $10 vehicle entrance fee.

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.
Run, bike, run. The multi-sport format without the swim. Two disciplines, one race — a great bridge between running and triathlon.
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.
A continuous race alternating open-water swimming and running across a series of segments. Distances, format, and legs vary by event.
