Bored with the gym, tired of the treadmill? Don't mind getting (really) dirty, love a challenge and can walk 10km? We have a fitness event like no other for you.
This is the inaugural year of the Western Mudd Rush, an obstacle-based endurance fun run with a difference.
TriEvents' Frances Quick said the event was not for the faint-hearted.
"This event is like nothing else, it will challenge the body and the soul of the participants," she said.
"The event consists of one 8km course with 18 obstacles - some tough, some challenging and some near impossible! The course will challenge all levels of the participant."
Ms Quick, events administrator, said participants joined in teams so they could help their mates get through the course in one piece.
"The Western Mudd Rush is designed for anyone with the balls to take it on," she said.
"It's all about camaraderie so you'll see the brickie helping out the CEO over an obstacle."
Ms Quick said the course used the terrain in and around the State Equestrian Centre, 45 minutes from the CBD, where participants would encounter obstacles such as the awe-inspiring Avon Slide and the Barbed Wire Scramble to test all physical abilities.
"Teamwork becomes a major part of the un-timed event as participants will help each other through the difficult obstacles and along the course," she said.
Ms Quick said there would be plenty of bands, DJs, food, alcohol and water (for those that need it) at the finish line.
"The post-event party at the finish line will be where prizes are awarded and everyone can cheer on their team mates through the last obstacle which is a secret," she said.
Motivate Invigorate Recreate: director Sandy Duxbury is taking part with her clients, the Bootcamp Junkies, and said signing up for a totally different kind of strength and cardiovascular-based challenge like the Western Mudd was a fantastic thing to do for fitness because the body adapted well under constant change.
"The changes increase your metabolism, firing up fat loss, increasing strength and cardiovascular fitness," she said.
"Enrolling in different kinds of fitness challenges keeps your body guessing, keeps motivation high to mix your training up and opens your mind up to different training methods and ideas for the future."
Ms Duxbury said a lot of the obstacles required all-over strength but particularly upper body strength.
"Men genetically have more fast-twitch muscles in their upper body than women and so are inherently stronger, however over half of the entries to the Western Mudd Rush are from women," she said.
Train with exercises that help build your upper body performance.
