Detailed description

The race starts on Yaugher Rd and gets straight into action with an 11km gradual climb up Kaanglang Rd, past Lake Elizabeth and past the ‘quarry’ to ultimately turn right down No.1 Spur Tk and Noonday Tk to cross the clear stream at the bottom. After which its a fairly savage climb up Noonday Tk back to the ‘quarry’ and the top of the KOM.

Back down Kaanglang Rd, a fun descent to Lake Elizabeth and soon after its the timed (and super fun) descent on the famed Michelin Tyres Red Carpet Tk – YEW! (see video preview of the track here). Riders then enter more singletrack heaven to complete the West Forrest singletrack network – including a full circuit of Follow The Dog – then its across the road into the new Flow Tracks before returning to the footy oval at the 43km pt. This section includes much of the newly developed and re-surfaced tracks

Riders then enter Yaugher trail network for 33+km of near continuous single track, ticking off trails like The Super Loop, Grasstrees, Marriners Run, Foxtail, J2 and plenty more. Re-fuel back the the footy oval at the 76km pt before embarking on the “sting in the tail” section of the race.

Exiting the footy ground a final time riders tackle a big climb up Thompsons Tk to the top of the Otways before a steep and fast descent on Newcombs Spur Tk that will truly leave you grining. The final climb up the “Sledgehammer” is back with it appearing just a couple of kms from the finish line. It will be sure to bring even our strongest riders to tears at this stage of the race.

Conquer that and you’re happy-days-rolling into the triumphant finish chute on the Forrest Footy Ground.

Remember, there is a lot of single track in this ride and a lot of climbing, so it is a true test of skill and endurance!

“Loved the single trails; the hills were challenging as hell but in a good way!!” – Douglas Murphy, 2022 100km Odyssey rider

“A true mix of varied terrain; the best riding possibly Australia all over – open road, climbing, bombing, creek crossings, berms, sand, mud, open fast single, tight single, in lush rainforest, in arrid sand… 100 Ks of a mix you won’t forget!” – Hugh Moll, 2021 100km Odyssey rider
