Grapevine: Webber confirms Tasmania event return

The event had not taken place since 2008, when the Australian broke his leg while riding a mountain bike.

The five-day, multi-sport event will see competitors across some of Tasmania's most stunning locations.

According to organisers, the event has attracted an "unprecedented" level of corporate and government support, with multi-vitamin manufacturer Swisse taking up the naming rights sponsorship alongside principal partner.

"After a three-year break I am thrilled the Challenge is heading back to Tasmania and that it's back on the calendar for the next three years," Webber said.

"The Challenge has always been about having determination and drive to give something a go. Now, as with the world's great endurance races, the format will allow elite athletes to chase ultimate success while others can turn up having never done anything like this before and amaze themselves with what they can do.

"Obviously you need to prepare for an endurance event - and with kayaking, trekking, trail running, climbing and mountain biking all part of the Challenge there is plenty to train for! But with five-day, three-day and one-day options we believe it is an event that has something for everyone."
