Aged 8 at the 31 December of the year race is held. 

This is the youngest age group at which children can take part in a triathlon and is based on age at the end of the year. TriStarts belong to Group S of our Saturday morning training groups .

Races are usually held on school playing fields on grass. Open water races are rare and if cycling on tarmac it will be on roads without traffic. Because of the very short distances, quick transitions are very important.

TriStarts can compete in our Club Championship and in the Eastern Region Children' League and there is asummary of all races on our East Region Race Calendar. On these pages the links tell you about each race and how and when to enter.

The standard race distances set out in the BTF rulebook for this age group are:

  • Swim 50m (pool) 50m to 100m (open water)
  • Bike 1000m (grass) 1.5km (tarmac)
  • Run 600m
  • Run 400m
  • Bike 800m (grass) 1.5km (tarmac)
  • Run 200m
