From the Organizer
The 18th Annual Race Montana Triathlon and Duathlon is scheduled for Saturday, August 22nd, 2026, at the Electric City Water Park in Great Falls, Montana.
The Race Montana Triathlon Sprint Distance event will start at 7:00 am. The event features a 500-meter snake swim in the Electric City Water Park 50-meter pool. The Bike portion will be 12.2 miles, with the first 5 miles and last 6 miles being relatively flat. Mile 6 is a steady climb to the turnaround. The run will be a fast and flat 3.1 miles. If you do not want to compete in all three events, get some friends together and compete as a team. Team racers will start the event with individual racers based on the anticipated 500-meter swim time.
If you do not want to swim, then DO a Duathlon!!! The Duathlon will feature a 1.0 - mile run that starts from the Bike Transition in the Electric City Water Park Parking Lot. The run is completely flat. Runners will return to the Electric City Water Park Parking Lot to transition to their bikes. The Bike portion will be 12.2 miles (identical to the Sprint Triathlon course) or 3 miles (identical to the Youth Triathlon Long Course). Upon returning to the transition area, athletes will complete the event with a final 1.0- or 3.1-mile run. "Do the Du"
Beginning at 9:00 a.m., there will be one of two Youth Divisions - making it an excellent event for the entire family. The Youth or ADULT Triathlon Long Course includes a 100-meter swim (2 pool lengths), a 3-mile bike, and a 1-mile run. The Youth Triathlon Short Course will start at 9:30 am and include a 50-meter swim (1 pool length), a 1-mile bike, and a ½-mile run.

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.
Run, bike, run. The multi-sport format without the swim. Two disciplines, one race — a great bridge between running and triathlon.
