Master the Run-Bike-Run with Specialised Duathlon Clothing

Unlike a standard triathlon, a duathlon skips the swim, meaning you can focus entirely on temperature regulation and transition speed. Our range of duathlon clothing features technical fabrics that wick sweat during the opening run and provide wind protection for the cycling leg.

Essential Kit for Every Duathlete

Tri Suits: The ultimate "set and forget" option. A tri suit features a thin, run-friendly chamois that provides comfort on the bike without feeling like a bulky diaper during your runs.

Compression Wear: Fight muscle fatigue across two separate running legs with graduated compression tights and socks.

Weather-Ready Layers: Duathlons often take place in the "shoulder seasons." We stock lightweight gilets, arm warmers, and packable windproof jackets that are easy to shed or add in transition.

Elastic Laces: Every second counts. Swap your standard laces for elastic versions to slip your running shoes on instantly during T1 and T2.

Traithlon Running Shoes: We stock premium run shoes from top brands like Brooks and New Balance to help you hit peak performance during your run. 

Shop by Experience Level

Beginner: Look for versatile pieces like duathlon shorts (same as tri-shorts) and breathable running tees that work for training and race day.

Intermediate: Upgrade to a sleeved tri suit for better aerodynamics and sun protection.

Elite: Explore carbon-plated running shoes and top-tier aero kit pieces like Bentoboxes designed for podium finishes.
