07 / The Field Speaks
WORD FROM THE COURSE
The best organised triathlon I've raced in ten years. Every detail was dialled in — I've already entered next year.
Plastic-free aid stations, a stunning course, and a finish-line atmosphere I'll never forget.
My first ever trail race and the marshals made me feel like an elite. The wooden medal is on my wall.
The 10km race was in a great location and the marshalls and organising team were helpful and friendly.
