TriUK is "the world's largest tri store" and has some excellent offers for equipment you may need: https://www.triuk.com
Wetsuit Hire: £39.99 (plus postage and packaging) for the whole season, from March through the end of August. For an additional £10 you can extend it until the end of Sept. TriUK introduced this scheme about 10 years ago as they believe that the more comfortable competitors are in their kit…the more they will enjoy their event…the more they want to come back and do it again. For just £39.99 for the whole season you can train and race in our wetsuits as many times as you want. Plus every wetsuit is brand new. They do not re-use their wetsuits. Every season they start with a fleet of brand new wetsuits.
Bike Hire: £150 (plus postage and shipping) for the whole season. Same format as above. Every customer gets a brand new bike and can train on it and race on it from March through to end of August.
There are also ex-hire wetsuits and bikes for purchase; plus complete triathlon packages available. Please visit the TriUK website.
