Why Buy Your Gear From

The Best For All Of Your Triathlon Needs!

One Tri was started in 2005 by triathlon enthusiasts just like you. At that time, we were frustrated by how hard it was to find quality triathlon gear. So we decided to open our own store and website in Orange County, California. We are more than just an online store. We are a community that cares for health, people, and planet. Let us know if we are accomplishing our mission and join us in our journey.

Our Mission:

Provide the best customer service and largest selection.
One Tri strives to provide our triathletes with the best possible shopping experience. Our goal is to provide the BEST customer service and the largest selection of products. Let us know how we can help.

Promote the growth of triathlon sports - swimming, biking, running.
We all win when there is a healthy following of our sport. Help us share the excitement, fun, and health benefits of triathlons. After all, we can all enjoy more gear, more races, and more fun!

Give to the charitable causes.
At One Tri we believe in maintaining a healthy heart both literally and figuratively. To do our part One Tri will always find a way to donate to, participate in, and support charitable causes.
