University of Canberra Stromlo Forest Park (UC Stromlo, former Stromlo Forest Park), Canberra, ACT

University of Canberra Stromlo Forest Park (UC Stromlo) is located in the heart of the Molonglo Valley, an easy 15 minute drive (15km) from the Canberra CBD. UC Stromlo can also be accessed by bike or horse through Canberra’s extensive path and trail networks. There is no direct public transport. Directions: click for directions.

Stromlo Forest Park is a public MTB track and you can ride it in the lead up to the race.


For a list of trails in the circuit, visit the LOCATION tab on the website.

Update 14/09/23 8pm: Race Track confirmed with slight decrease in lap length and elevation.
The team was on-site marking today and has finalised the race track to align them with the changed traffic conditions and the construction site at UC Stromlo. The race track is slightly shorter and elevation a bit less.

Race Track Stats:

  • Course length 28.2km.
  • Climbing 760m per lap.
  • Approximately 75% of the trails in Stromlo used or partially used.
  • Single track is broken up by 11 sections of forest trail.
  • Two major climbs: the gentler front face to City View (5km at an average of 5%) and the more punishing “Casuarina Climb” on the northern side (2km at an average of over 10%).

Race Circuit: click for detailed race track description incl. Stromlo track names on the website LOCATION section and make sure to check out the video rider briefing for final details.

Be aware: whilst we have booked the entire race track set out in the UC Stromlo trail network, you may encounter public riders on the trails. The event is published prominently, but be prepared for non-racers on the trails and may we ask that you are courteous. We will have marshalls on course who will help spread the word, if there are any issues, please report them to our crew or back at the event centre.

You can Choose Your Own Challenge with the options to ride the Single, Double, Triple or Miler

In this circuit race the distance challenges are on a 29.8 km loop:

HERO Triple: 3 laps for the full marathon challenge
ADVENTURE Double: 2 laps – the most popular distance
CHALLENGE Single: 1 lap for a relatively quick but still hard race
The 100 MILER: 5 laps which has a small but very dedicated following of hard racers

The traditional start is a mass gun start for the first three classifications and there is usually a short addition to the race circuit, an extra bit of firetrail, to avoid congestion on the first lap. Start for the 100miler is very early to give you that rewarding morning lap and let’s you finish with the crowd. After each lap the times will be recorded at the event centre; the fastest rider in each category wins. Male and female age categories offered include Junior, Elite, Master and SuperMaster.


There will be rolling podium presentations as category 1-2-3 placings are confirmed. Various product prizes and Rocky Trail race vouchers for the Jetblack 24 Hour and our brand-new Effervelo Gravel event will be presented.
