A Triathlon consist three disciplines, usually swimming, cycling, and running in consecutive order. 


Events cover various distances set out by the governing body Triathlon England and competitors race against peers in their age category.


Taking part in a triathlon is very much achievable for everyone with practice. We run sessions throughout the year on each of the individual disciplines of running, swimming and cycling as well as holding small-scale triathlon events in the lead up to the Big Lime Triathlon.  All sessions are run by qualified instructors.

Entries are now open for next year’s Big Lime Weekend, an amazing three days of multisport running from Friday 14 August to Sunday 16 August 2020.


Located in the historic Hartlepool Marina and along the Seaton promenade with stunning views of the expansive sandy beaches, the weekend kicks off with a Friday evening predictor swim. Saturday will see competitors tackle the Aquathlon, before the weekend is rounded off on Sunday with the adrenaline-pumping sprint triathlon event.


People are being urged to support all events across the three days, as competitors, spectators, families or as part of the team of volunteers that plays a key role in making sure the events run smoothly and continue to be a huge success.


All events are open to both experienced athletes and novices, and the weekend is expected to be just as popular again this year, so make sure you book your space early to avoid disappointment. All finishers will receive a medal in addition to goodies and an opportunity to purchase T-shirts.

Hartlepool Tri Life

Hartlepool Tri Life, some say triathlon is all about achieving and pushing yourself to your limit in order to reach impossible goals. We say that tri is also belonging, feeling the support of those around you, complete strangers urging you forward when you’re feeling the pain. Triathlon is a big family. Come along to a coached Tri-Life session and see what it’s all about.
