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.

AVENZA MAPS

We highly recommend everyone downloads the AVENZA Map for the race before the Event. If you do not have a way of loading a gpx file into your watch, this is the next best thing to allow you to get back on course if you are unsure where you are. Course tampering does happen, or people miss a turn easily in trail running. So you need to have a map to know where you are.

Download the AVENZA Map App to your phone and in the Store search for the Keywords “Roller Coaster Run 2025 23k”. Then click “Free” and it will download the map for offline use on your phone. If you open the map, as long as you have enabled AVENZA to use your location, you will be able to locate where you are on the map and which way you are facing by clicking the little arrow. You can open and use this map even with no reception.

When you have the map open, have a play around. It is very useful. You can see the coordinates of the pointer down the bottom of the screen as you pan around the map. You can also press the draw icon in the bottom left to measure the distance between points.
