The Crown is under way in Copenhagen. Tune in.
Back to Southampton for the two-day final, and one step up the podium from last year: 2nd in the Female 16–17. Next stop Copenhagen. Photos to follow.
I’m Lucy, I’m 17 - a teen athlete from Cambridge, UK. I got into CrossFit because girls weren’t allowed on the rings in our gymnastics class, which felt deeply unfair.
In 2023 I tried a CrossFit class with my dad and was hooked. From my first Open ranking at 321, I climbed to 15th in the semis in just three seasons. After the semis in 2025 I made the transition from doing CrossFit as a hobby to training full time.
I’m really lucky and proud to be part of the amazing community at CrossFit RNA: a small affiliate with a big heart! I love the variety of skills that CrossFit covers, especially the more technical moves, and I take great pride in my execution.
When I’m not working out I work as a stable hand, have a small horse-care business, and I’m vegetarian.
I competed in the Teen Games in San Jose in July. Getting there is an online funnel: Open, Quarterfinal, then Semifinal, each round a smaller, already-filtered field. The Semifinal is the one that booked my seat. Since San Jose I’ve taken 2nd at the British Masters & Teens finals and picked up an invitation to Copenhagen in December. The climb below is the long version of the story.
165 lb, at 58 kg bodyweight. Only three athletes in the field went heavier.
19th on the row half, 6th on the ski half. Same legs.
Bar muscle-ups and handstand walks, finished inside the cap.
Strength, skills, fitness. A top-10 in each.
Round by round, oldest first. Lower is better.
| Competition | Division | World rank |
|---|---|---|
| 2024 Open | Girls 14–15 | #321 of 1317 |
| 2025 Semis | Girls 16–17 | #92 of 132 |
| 2026 Games | Girls 16–17 | #16 in world |
| 2026 BM&T Finals | Girls 16–17 | #2 in Britain |
An athlete on the rise.
More where these came from: @lucytristem
I’m internationally qualified at 17, the numbers are still bending the right way, and I’m invited to Copenhagen in December. There’s a steep climb ahead and room for a small number of partners on it.
I want a conversation with a small number of partners who are genuinely interested in the climb, and who want to be part of it. I’m looking for kit and apparel support, vegetarian fuel, and help with the cost of competing internationally (Copenhagen in December is the next one). If that’s you, let’s talk.
Authentic content. I do the work either way; you just get to be in frame.
Best way to reach me is email. For the day-to-day, the training and the misses as well as the wins, follow along on Instagram.
