5K races near Canberra

Canberra Training Notes

Canberra hosts 2 5K races in 2026 within 80 km of the city centre — upcoming dates, recurring series, and other races nearby, all in one place.

Lake Burley Griffin is the easy default, because the 5km central basin loop, the 9km eastern loop, and the 28km whole lake circuit all keep you moving by the water. Locals use Commonwealth Park, Lennox Gardens, Ginninderra, Tuggeranong, and Point Hut Pond for steady Z2 and cleaner intervals. Mount Majura and Mount Ainslie feel like second home trails when you want dirt and a climb. Canberra Runners, Capital Athletics, Underground Run Club, Females in Training ACT, and Achilles Australia keep the week social. The Canberra Times Fun Run is the flat PB day, while Black Mountain Run Up and Mt Ainslie Run Up bring the sting.

Stromlo Forest Park is the grubby bike home base, and it gives riders more than 50km of cross-country trails, dirt jumps, and proper zones for every skill level. Locals love Majura Pines, Cotter Pines, and Stromlo Forest Park for flows, jumps, singletrack, and cyclocross legs. Canberra Cycling Club brings Wednesday Worlds, crit energy, and gravel, while Canberra Off Road Cycling Club and Pedal Power fill in the dirt and daily-riding side. The Canberra Centenary Trail runs as a 145km loop, and the Epic Canberra Gravel Trail gives you 75km with 77% gravel. The climbs sit around Stromlo, the Arboretum, Cotter Uriarra, Tharwa to Horse Gully Hut, and the Brindabellas south and west.

Autumn is the sweet spot, because Canberra mornings stay crisp, calm, and manageable once you warm into base miles. Late spring brings the highest rainfall, so locals still train, but they watch thunderstorms between October and April. January carries an average high around 28°C, so runners and riders start early, stay near Lake Burley Griffin, and leave hard intervals for cooler windows. July drops the average high to about 12°C, and frost makes gloves, layers, and windproof kit normal. Winter runners still use the lake and hills, while winter riders treat a 10kph headwind at 5°C like a proper cold-day test.
