MomsTRI is a women’s triathlon where we celebrate each others accomplishments.

The triathlon is designed for all women and is the first event of its kind in the Phoenix West Valley.

Whether you’re a veteran or a novice triathlete, this race is for you! Our sprint triathlon is focused on inspiring beginners and non-athletes to join with other women in loving their bodies and feeling unstoppable!

We are proud to support New Life Center, our local emergency shelter for victims of domestic violence. A portion of every registration goes to supporting the refuge provided to women & children escaping violent situations. Please consider making an additional donation when you register.

MomsTRI starts at the Goodyear YMCA Olympic pool for the 400 meter swim. You’ll love the flat bike course, consisting of three 4-mile loops and a quick run (or walk) through Goodyear Park and the surrounding neighborhoods. If you’ve participated in MomsTRI before, you know our finisher’s party is the perfect place to celebrate your accomplishment! If you’re new to MomsTRI, we can’t wait to meet you and share the fun with you!

This truly is an event for every woman!

If you can’t join us in-person, register for our virtual triathlon. You’ll still get the same awesome MomsTRI swag with the flexibility of a virtual race!
