Welcome to Tri3 Sleaford Triathlon Club


Tri3 Sleaford Triathlon Club was launched in 2013 and is a community club, run by local volunteers. Training sessions are held in Sleaford and the surrounding villages with the aim of encouraging sport for all. We are a sociable club with a growing membership and a well-established junior section.

We welcome triathletes of all abilities from complete novices to experienced age groupers.  

Current sessions are held at:

- RAF Cranwell swimming pool

- St George's School

- Heckington Pavilion

As the weather improves, we will re-start social rides and run sessions. Please see the training page for more details.

If you are interested in joining our club, you may attend 3 sessions as a taster prior to joining Club. After this, for insurance reasons, you are required to become a member.
