ESSENTIAL DUATHLON KIT

Optimise your off-season training with the right training gear

The Huub Transition Jacket (£139.99) is lightweight, wind and shower-proof, and is designed to keep you warm pre- andd post-race.

Your usual tri-suit might be a bit skimpy for colder duathlons, in which case the Orca Winter Race Suit (£129, left) boasts Featherlite Windshield that will provide warmth and block wind.

Stash a Buff (from £15.50, left) in a pocket and it can act as a head-warmer under a bike helmet, a hat on the run or a neckwarmer during any stage.

If it’s properly cold, then a base layer such as the Craft Active Intensity (£34) is a great addition for the run and bike legs. These Kalf Arm Warmers (£20, right) are an easy and versatile way to add warmth without full extra layers. Just stash them in a pocket.

The Elite Nano gelite (from £22) will keep your beverages warm for up to four hours due to the Nanogel insulation properties. A life-saver on long, cold weekend rides.
