Performance. Backed by evidence
Independent testing at Loughborough Sport evaluated three athletes — beginner, intermediate, and advanced — across four 750 m swims each, with and without Zone3 wetsuits.
Averaged results demonstrated measurable improvements in efficiency, speed, and physiological response across all suits, with outcomes varying by individual.
National Tri Day
National Tri Day is a new annual event, officially registered and created by Zone3 to bring the triathlon community together at the start of the season. We’re launching it at Divers Cove with a special open water event featuring wetsuit testing, a free short swim loop, coaching, athlete insight, partner activations, giveaways and more. Scott Hill will lead a live coaching session, while Kieran Lindars joins us for an athlete Q&A fresh from setting a new British long-distance record. Open to all levels, it’s a chance to get in the water, learn from the right people, and start the season on a high.
CASPER STORNES CHOOSES ZONE3
Casper Stornes is the reigning Ironman World Champion, the most respected title in triathlon.
