Walking 100km non-stop may not sound like an easy feat but two of Miss Universe WA's 2013 top 60 beauties, *Rachel Falzon * and *Jade Fairbairn, *were more than happy to clock up the distance at the weekend in the name of charity.
The two girls trekked the gruelling distance non-stop on treadmills at Hurt Locker in *Claremont * to raise money for children's charity ToyBox International.
Kicking off the harrowing walk in the early hours of Saturday, both Falzon and Fairbairn completed the trek in 12 hours but were lucky enough to get support from a bevy of other Miss Universe WA girls who turned out to cheer on the duo.
While the pair were said to be exhausted and suffering blisters to their feet, Falzon said it was an amazing experience.
"We wanted to physically challenge ourselves to earn the money (for ToyBox) and it felt great achieving our goal," she said.
The girls raised more than $1500 at the weekend.
It is the first time both girls have embarked on the Miss Universe WA journey. Fairbairn has been modelling since she was 12, but will hit the catwalk for the first time at the weekend for the Armadale Shopping City Parades.
