The Fifteen branding is bold, energising and full of heart. It’s not just about crossing the finish line—it’s about the legendary journey you take to get there.

Fifteen is a London-based fitness race training club with a twist. The brand’s name stems from the insight that training in groups can boost fitness performance by an additional 15%.

Founder Brittany wanted to create a brand that captured that energy—where modern athleticism meets the epic spirit of Greek and Roman mythology. The goal was to make Fifteen feel social, strong, and totally unforgettable, just like the team experience it offers.
