What does it take to make the perfect kit for winning triathletes? Castelli takes us behind the scenes with this new video showcasing their quest to design the perfect race kit for three-time world champion, Mirinda Carfrae.

Carfrae, also known as “Rinny” is headed back to the Big Island this October on her quest for a third Ironman world title after bad luck and injury forced her to DNF last year. The superstar has focused much of her racing on the 70.3 circuit this season, earning some podium finishes and a win at Ironman 70.3 Timberman along the way, but is choosing to sit out of this weekend’s Ironman 70.3 World Championship in favour of giving herself more Kona-specific prep.
