“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

The 100km Otway Odyssey has a solid reputation… this is the ultimate mountain bike marathon – a heroic mountain bike journey through a range of wild landscapes and cranking single track. This is a TOUGH COURSE allowing you to show us what you’re truly made of… are you up for the challenge?


The 2022 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 Red Carpet Tk – YEW!. Riders then enter more singletrack heaven to complete the West Forrest singletrack network – including a full circuit of Follow The Dog – before returning to the footy oval at the 41km pt.

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 74km 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 most grown men 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!

Rider Etiquette

Passing etiquette – TAKE NOTE!

With a large number of riders a narrow trails there are a few points of common etiquette when it comes to passing a rider that we ask ALL RIDERS to be aware of. (Seriously – being passed by a fast rider is an incredibly intimidating thing for some riders so please be aware of these points).

If you are a faster rider who wants to pass a slower rider:

  • Let the slower rider know you are there and want to pass. Say something like, “Can I go past when there’s a chance…” or even “Track please” if you’re short of breath. Then wait for a wider section of track – don’t just barge on through
  • The slower rider can then say, “OK, go past on the right” or “just up here it’s a bit wider, go there”. But it’s good to acknowledge that you heard them and give direction for when they can go past
  • The faster rider should not and does not expect to go past the moment they catch you, slower riders should stick to their line and call them through when it suits both of you
  • If you are going to pass then make sure you are actually faster, don’t pass if you are pushing 120% effort to get around them and then slow down afterwards

Both riders should leave your ego in the car park and simply communicate that you want to pass and agree a point when it suits to pass. Happy riding!
