The exact details of all challenges will be kept secret until the event. The WARTS came second last year and with six new members in the team this year, the determination to win was clear.
"I reckon we've got a good chance of winning, or coming top three," team captain Lochiel Espiner said.
"We didn't really set goals about it, we just kept doing the training and preparation for it but deep down everyone wants to win it."
Only two of the current team were involved in last year's close loss to the team from New Plymouth Boys' and Girls' High Schools. However, nearly all members remembered a bitterly narrow loss to a team from the same schools when they competed in the junior version of this competition.
"If we could pick one team as rivals, it would be them because we are always head-to-head in the competitions we do," Espiner said.
All members of the team performed a role throughout the challenge such as timekeeper, food and water provider and leader. Alysha Donovan and Adyn Dudley, who would perform the roles of motivator and back-up navigator respectively, said it was the little things like a change of food which could heighten any dampened spirits.
"We all like fruit and stuff, we are big cucumber fans," Donovan said.
"A cucumber is quite refreshing, after a day of eating nuts and dry food, getting a cucumber is quite exciting," Dudley said.
Year 13 student Johnny Wilson was in his second year of the senior Hillary Challenge competition and said the extreme physical and mental exhaustion was something you had to accept to get through the week.
"It's only for a week so you just have to grit your teeth, bear down and do it," Wilson said.
Wilson, who will be the navigator, said it was important to understand your team members and assess their energy levels.
"It's just about having the mind frame that it switches so you might have lots of energy at one point, and then you might go through a massive low and you need help."
Even though the Hillary Challenge was centred around pushing contestants to their physical and mental limits, Wilson said it had a lot more benefits which athletes didn't get from playing other sports.
"You do all this training and when you're finding stuff hard at school, you know you'll find a way through it because you can in this race which is 100 times harder."
