2025 Ugly Dog Gravel Triathlon

Voted one of the top three Best Sprint Triathlons in the nation from USA Today.

Next July is going to GET UGLY. Join us at the Original Gravel Triathlon event on July 26, 2025 in Grass Lake, Michigan.

Ugly Dog Gravel Tri is a swim – gravel bike – trail run event. Your race will start with a beautiful swim in Portage Lake, located at the Waterloo Recreation Area. Then get ready for the bike leg, but leave the expensive tri bike and skinny tires home. Grab a road bike, fat tire, mountain bike, whatever is going to take you through the gravel roads. Once you are back to transition, finish off your race with a wooded trail run.

We feature a super-sprint and sprint distance race, which is PERFECT for anyone who wants to try out their first gravel event or for those who enjoy the short and fast distances. We also offer duathlon, aquabike and relay options.
