Kids triathlons in the UK
Triathlons for children and juniors are a great way to introduce them to the sport. Courses are usually short and held on closed roads to be safe and accessible for kids. We've made it super-simple to find events by age - but don't forget, it's usually the child's age on 31 December of the year of the event!
