It’s a fast downhill start along Anzac Parade, taking in the views of Parliament House as you head towards Lake Burley Griffin. A smooth bike path winds its way around central basin, across Commonwealth Ave bridge, via Lennox Gardens and up to Parliament House.

Next up is a douche grade climb up Melbourne Ave as you head for the trails at Red Hill!

It’s time to hit the dirt and the hills as you climb up some single track and stairs, past the Dr Who Tardis and top out at Red Hill Drive.

Taking in the views at the first water station, 100km’ers will continue South along the ridge line fire trail and single track. Bag another trig point before descending off the ridge and looping back to join the 25km course via single track along the edge of the Federal Golf Club.

After exiting Red Hill Reserve you work towards the Governor General’s Residence via West Basin bike path. Scooting over the top of Scrivener Dam, you will hit Checkpoint 1. Soon after this, the 25km course splits right towards Black Mountain while the 100km course loops up and around the arboretum perimeter fire trail and through the Cork Oaks to re-join the 25km at the South West corner of Black Mountain.

100km Challengers head directly up the Black Mt summit walking track. Just before the top, there’s a small excursion around to the left and up and a few more stairs. Your reward is the next water station at the top!

Back down the summit trail and turning left to contour around the flowy necklace single track (course highlight!). Crossing Black Mtn drive and dropping over the back of the carpark, you will tackle a technical rocky descent past the water tank. Turning left you will follow an undulating fire trail behind the botanical gardens and down to the CSIRO substation.

The centenary trail takes you along some gentle single trail, underneath Barry Drive and winds over to Bruce Ridge. Cruising along the footpath, under the GDE and towards Gossan Hill where you will hit the dirt once again. A small climb up and over Gossan Hill, before a smooth descent down towards the Uni of Canberra campus.

Another underpass will get you through to John Knight memorial park as you wrap around the edge of Lake Ginninderra towards the bridge and the next water station!

Follow the bike path down to the right along Ginninderra Creek, until you pass under the Barton Highway and loop North West towards Gold Creek. A mix of footpath, café’s and sneaky single track will take you towards the main street of Hall. Palmer St runs parallel to the main street and here you will find Checkpoint 2! Time to fuel up for One Tree Hill.

Heading North Eat from Hall takes you up the centenary trail single track towards One Tree Hill. A steady but gradual climb for 4km and you will hit the border track between ACT and NSW.

The single track joy continues as you snake around the border, wrapping in and out of trees and through a weird garden of rock cairns – get your camera out! There is also a campground with drop loo and a water tank (don’t rely on it though).

Before you know it you will pop out on to Mulligans Flat Rd – cruise along the bike path to Checkpoint 3!

Rolling fire trail takes you through Mulligan’s Flat Sanctuary and towards Goorooyaroo Reserve. Make sure you close the really big gate! There is a water station as you cross Horse Park Dr. Enjoy the flat runnable sections while you can because you’re in for a hilly finish!

Underneath the Federal Highway and you will meet a fire trail climb up towards Mt Majura Rd. Thankfully you can turn left and sprint downhill, looking for a turnoff on your right to some single track that winds down towards the winery and Checkpoint 4! Don’t stay too long because you’re nearly home.

Rolling along the side of Majura fire trail you will spy some mountain bikers weaving in and out of the Pines. Turn right and get ready for a steep pinch of hiking up towards the saddle. Once you hit the saddle, veer left and enjoy the gradual but technical zig zag descent down the Casuarina Trail. At the 4th hairpin, continue straight off the edge and the track will take you down to a fire trail and large water tank at Majura base.
A short fire trail climb takes you over Hackett Hill, before you veer left near the top and follow the fence line down towards Campbell Park. A right hand turn will take you through some grasslands to link up with the power line trail. Turn left up the Centenary single track and climb towards the road. You will find some sneaky single track that climbs gradually beside the road, then finally some stairs to pop you out at Ainslie summit! There is a tap if you’re desperate for water.

It’s all downhill from here – follow the main walking track most of the way down, before veering right on to a fire trail that leads you back into the finish at Campbell High!
