Leg 1 Run - 16.5km Run

Forts Carpark

Your run will begin from Picnic Bay and head over into Rocky Bay (with small sections of rock hopping and onto the Gorgeous Rocky Bay Beach). Ignore/run past the ropes/abseil section (this is exclusively for the Ultra Adventurethon competitors – if you desperately want to do this section, you will need to step up to the Ultra) and continue running along the beach rock hopping where needed and then turning off into the suburban section of Mandalay Ave where the next great section of trail begins.


Rock Hop section

The Nelly to Arcadia track is a favourite piece of trail amongst bushwalkers and trail runners and offers a gradual climb to the Checkpoint and then a further gradual climb before descending and then peeling off towards the Forts track rather than towards Alma bay. You will then climb to the forts and take in that area before descending an old 4wd track which is quite steep and become eroded over the years. Once at Radical bay Rd it’s a quick skip to Radical Bay and onto the beach before rock hopping around to Balding Bay and onto the track back to Horseshoe bay for the end of the run.

Leg 2 MTB –  32km MTB The mountain bike leg of the Dirty Duathlon consists of 2 laps over a mix of Course terrains. This course is a tough physical challenge with a few testing hills and fun descents as well as un-manicured, good old tough, rocky terrain on both the climb and the descents. The addition of some new sections of Private horse riding property will make for some flowy sections to start and finish each lap on (please avoid these sections in any training)

Ride through the flats of Horseshoe bay Via the Horse Property, exit the property via a single-track running near the edge of the road and heading up towards the Forts carpark. Once you get in line with the carpark swing right up a steep climb until you descend to the road. Dismount (and safely cross the road) and head into the Telstra track… this section is a pretty steep section with some rough terrain, but it is heaps of fun for those experienced riders to enjoy with the challenge something the less experienced riders should be stoked to get through. After the Gnarly descent it’s a fast downhill surge down the bitumen, where the lungs can be inflated again and the body cooled before heading down Mandalay ave and taking on the pipeline trail.

Riding out from CPC

The pipeline trail is a rocky tough climb where line choice is very important and momentum is your friend, keep it at all costs to make this easier (New additions for this bit of trail challenge is to ride all the way to CPC). At the pinnacle you will get to the checkpoint C and descend a Fire trail called Savage canyon otherwise known as hell. The section is very prone to erosion and so a series of water bars criss-cross the trails. Sections of these erosion bars can be carefully descended and make for a bit of fun, as the hill gets less steep people will let their brakes off and allow the momentum to take them down the hill towards Horseshoe Bay.

Once at Horseshoe bay, the trail spits you onto a section of bitumen where you can quickly sneak in a drink or snack before heading towards the Horse tracks and a great winding section of trail makes for heaps of fun…the speed will be dictated by the Flow of rain in the days leading into the race as these sections have a few creek crossings in the wet BUT are bone dry when thee has been no recent rain.


Leg 3 – run

The finish will include racking your bike at transition and running up the beach for a approximately 200 metres, before crossing the finish line
