Group S

(TriStart - born in 2011)

train for one hour from 9.00 am to 10.00 am on Saturdays during school terms, mainly at Lord Butler Leisure Center. From Sept 2018 the group is for those who were born in 2011 who will race in the Tristart age group in 2019.

The aim is to introduce children to the sport in a fun way, with plenty of games with a high emphasis of developing balance and coordination skills and safety whilst cycling.

Children joining the group will be expected to be able to swim front crawl for at least two lengths without holding on to the sides.

Arlene Mclean is the Group Leader and can be contacted at She is supported by Sam Hughes and Nicola Baxter.

You will find details of how to apply to join Group S on the membership page.

WaldenJNR Tri Start members in action

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
  • Swim 50m (pool) 50m to 100m (open water)
  • Run 600m
