Down Clarence Valley Road, turning right into Tophouse Road, then turn right up Jollies Pass Road. This is followed to the top and all the way down to turn right into McIntyre Road. You then turn left on Jolliffe Road, right onto Pawsons Road, and left on Clarence Valley Road to finish back at The Domain.


Unfortunately electric mountain bikes are not permitted on course.

Track Changes

Occasionally tracks will be required to be changed slightly due to situations out of the organisers control. 

Transition - Jacks Pass

Due to the increasing congestion at the transition and problems with parking of vehicles and rider safety, individual competitors will not be allowed a support crew at the transition during the race. Please respect this ruling and help us to make the race safer for all competitors  Full details of the layout will be provided in your race pack.  

Bike stands and marshals will be on Jacks Pass Road from 7.30am to allow individual competitors to position their bikes, helmets and other gear before attending the race brief. This will be done in numerical order and bike numbers must be on bikes prior to this. We strongly suggest you register on Friday evening to allow time foe this and suggest you allow at least 1 hour in order to position your bike on Saturday morning. Once you reach the top of Jacks Pass, please park as directed on the Hanmer side of the pass and leave the area as soon as you have positioned your bike. Remember, this is a narrow road and there will be lots of traffic using this area on the morning of the race

Team Competitors

Team competitors will be allowed one vehicle to go to the transition, and as far as possible this should only contain the biker for that team. No team vehicle should go to the transition until after the race brief when there will be approx 15 mins before the runners start, thereafter vehicles will only be allowed on the road once it is clear of runners. Please combine transport as much as possible.
