Elevation: 1000+ (ITRA re-evaluation in progress)

Note: The National Arboretum loop of SRF50 has been re-routed due to new bitumen sealing of trail paths.

The first 20km of the race is a scenic loop which travels east along the Molonglo River and climbs through the National Arboretum to the top of Dairy Farmers hill, providing a stunning view of Canberra and Lake Burley Griffin, before returning through pine forests back to the main event hub.

The next 30km follows the same track as the SRF30 course, taking in the eastern and northern lower slopes of Mt Stromlo before heading out the back of Stromlo Forest Park and taking in spectacular views looking west to the Brindabella Ranges. Runners make their way up the mountain to conquer “The Mother” aka the top of Mt Stromlo and take in all the glory of the Canberra region at this selfie-worthy point. The final few kilometres are a descent back down to the event hub and the finish line.

SRF50 consist of stretches of relatively flat ground with numerous rises and two major climbs for a total of 1020m vertical gain and is suitable for intermediate/advanced runners prepared to be out on course for a several hours with a cut-off of 9.5 hours for this event.

Runners can expect the course will be well marshalled and marked to ensure they can run carefree and enjoy the race without worry of navigation.

Course update 3 March, 2022
We have been closely monitoring the Molonglo River crossing as well as a section in the forest between Coombs and the Arboretum. For safety reasons and track degradation due to works in the forest these will both be re-routed [MAP]. The changes are estimated to add less than 500m to the course. There is also a small update between the 1km and 2km point. Be assured it will be very well marked and will be re-evaluated by ITRA post event for accuracy.
