Course Description

Commencing at the Event Village at Kalorama Memorial Reserve, runners depart along Hands Rd, then Jasper Rd and continuing to Old Coach Rd. These low traffic roads will be marshalled for clear direction.

A right turn onto Old Mountain Rd brings runners to a very fast downhill along a dirt road which comes to a split and runners veer left onto Fireline Track. This is a nice trail which undulates slowly uphill til you get to the left turn onto Observatory Track. This is perhaps the steepest climb of the race and it lasts long for a good 130m of Vert.

At the top right turn onto Kyeema track, runners follow this trail across the hillside catching a great view as they go by Burkes Lookout. Bomb the descent down the zig zag track through tall Mountain Ash and Rainforest Ferns before emerging at Doongalla Picnic Area, a serene opening and the home of Checkpoint 1. 

Runners then proceed out of the access road of Doongalla and take a hard left onto Dodds Track where the challenge really begins with this second very steep climb part of the Roller Coaster Folklore. 

Runners then cross the Basin-Olinda Road and continue on up Range Road before gradually curving around, running a bit of a Roller Coaster and making their way back to Doongalla for some much-earned refreshments.

Leaving Doongalla for the second time, runners head north, making their way along Camelia Track and Singleton Terrace to the back of the village of Kalorama with more stunning views as a backdrop. 

Runners then return along Old Coach Rd, Jasper Rd and Hands Rd to the Event Village at Kalorama Reserve.

From the Event Village runners turn around and do it all again – in reverse! It’s amazing how much different the loop becomes once it is tackled in the opposite direction on tired legs. Most runners admit that the focus changes and the course comes to life.
