Event Day

Kit Checklist





The triathlon-specific wetsuits will not only keep you warm but will also help you swim faster as it provides you with extra buoyancy. Surf and shorty wetsuits are allowed, but these are very different to a triathlon specific wetsuit, which is designed for open water swimming and fits like a second skin. For more information on wetsuits, visit our official swim partner Zone3 here.



If you have not already done so, the easiest way to hire a wetsuit for the day is to visit the Zone3 website where you can get an award-winning Zone3 wetsuit for the day. We strongly advise you to swim in your wetsuit before the event. Practicing getting out of the wetsuit will help with your transition on the day too.

*Top tip: a nonpetroleum lubricant (e.g. Zone3 Wetsuit Glide) on the wrists and ankles will help.*


Find out how to correctly put on a wetsuit with these tips from Zone3 and avoid cosmetic damage from nails and jewellery. If you haven’t tried on or swum in a triathlon wetsuit before there are a few things you need to consider – from fit, to actually getting the thing on! The Zone3 product development team work hard to ensure their wetsuits are super flexible, ultra-buoyant, made using the world most technically advanced materials so you can  benefit and ultimately #ReachNewLimits this year. For more information, see our wetsuit buying guide


Fixed wheel bikes (bikes that use the pedals as a brake) are not permitted in the race. Your handlebars must not have bare open metal ends. Please obtain stoppers to plug them before coming to the race. BTF Referee bike checks can potentially stop you competing.

Bike Helmet

*A bike helmet is compulsory.*

Approved cycling safety helmets of ANSI Z90.4, SNELL B90, EN 1078 or an equivalent national standard must be worn by competitors. (NOTE: a CE mark is NOT an approval mark).

NB: any helmet bought in recent years will comply but check for damage, which would stop it protecting you properly.
