Welcome to Giant Odyssey


DATE: Saturday 20th February 2016 - NEW DATE!

LOCATION: Forrest (Great Otway National Park), South-West Victoria

               - Giant Odyssey 100km
               - Giant Shorty 50km
               - NEW Giant Rookie ~25km
               - NEW Giant Pioneer 10km
               - NEW Giant Grommets fun riding for (little) kids

By popular vote (in the post event competitors' survey) the format of the 2016 Giant Odyssey will be the same as 2015 and earlier years with the same 100km and 50km courses and the event starting and finishing at Forrest .

But NEW for 2016 will be the medium distance Giant Rookie ~25km event – a race that’s custom designed for MTB newcomers, keen kids and those not quite up to 50km. Other evolutions mean that the Giant Pioneer will be shortened from 15km to 10km to be even more friendly for kids and we’ll include a new Grommets Ride for little kids on balance bikes around the Forrest Footy Ground.

The Giant Odyssey remains Australia’s most respected MTB marathon with an even broader range of events to cater for all riders. Lock it in for 2016 and our celebratory 10 year edition.

ENTRIES: Will open in mid September.
