Kit List


Under current British Triathlon Federation rules, the following temperatures are enforced for events to ensure the best safety for swimmers:

Swim Length: Up to 1,500m
Wetsuit Forbidden Above: 22°C
Wetsuit Mandatory Below: 14°C

Tri suits, swimming trunks etc. are fine. If wetsuits are banned then competitors are OK to swim without tops on, so bare torsos are permitted, but only for the swim leg. Sports bras are fine, but again, athletes must cover up for the rest of the race.

Please note an updated water temperature reading will be provided in the lead-up to the event.


All bikes MUST be racked by 9.40am.

You can leave your race gear in the transition area. ONLY those taking part are allowed in to transition.

We will provide swim caps which can be collected on the day.

The race will start at 10am sharp and will go off in 5 minute wave intervals.

You will receive details of your wave group and time in an email prior to the event.

Please make sure you come prepared and have all your essential kit with you, including wetsuits which are recommended for the swim and helmets which again MUST be worn on the bike.


This is a fantastic event for spectators who can come along and recreate the epic atmosphere of the London 2012 Olympic Games.


Volunteers are integral to making Fix Events the great spectacle which they are.

Your role will be to marshal on the course or help within the event hub giving participants plenty of support and encouragement

In return, volunteers will receive free entry into one Fix Event. If this sounds like something you would enjoy, then get in touch with [email protected]
