T9 MERMAID RACE SERIES

The 2022 T9 Mermaid Race series is here, with in-person AND virtual races.

Designed for every woman, every age, and every body, the T9 Mermaid Series is more than a race: it’s a celebration of women’s movement. Whether you’re running your first 5K, working on a new half-marathon PR or tackling a tri, you can count on our kickass community supporting you every step of the way...and on some seriously sweet bling at the finish line.

So grab a friend, the baby jogger, or just show up solo, and get ready to rise up and throw down—we’re waiting for you.
