A list of links to Tristar Open Water Triathlons for junior triathletes requiring kids wetsuits in the UK during the 2018 season. Events for TriStart and TriStar youth categories using Lakes for the swim leg of the Triathlon.

Do I need a wetsuit?

A wetsuit will not only keep you warm but it will also help you swim faster, providing you with extra buoyancy across the backside and down the back of your thighs. This keeps you higher in the water, so you swim faster. It will aid your swim immensely, reducing fatigue. It is also compulsary to wear a wetsuit if the water temperature is less than 14 degrees.

Can I use my surfing or shortie wetsuit?

Triathletes require triathlon-specific wetsuits, which are very different from normal wetsuits. Designed for swimming, flexibility around the arms is incredible and won’t impede your swimming. A triathlon wetsuit also fits extremely closely. Beginners usually think their wetsuit is too tight on the chest. Any tightness will immediately disappear as soon as you enter the water. Hiring a wetsuit and practicing before your event is a great way to prepare.

Typically, a kids trisuit is worn underneath for the bike and run legs of the event.
