Canberra marathon is a standard 42.195-kilometre marathon around the Australian capital city. The marathon, which was established in 1976, is said to be the oldest city marathon in Australia. It takes place early in April each year and comprises a festival of races: 10 km and 5 km races on a Saturday, and the main marathon as well as an extended or ultra marathon on the following day.
The marathon starts at Telopea Park School in the suburb of Manuka, which is within sight of Parliament House. The route starts with a 10 km lap around the old and new Parliament buildings and other major government buildings. This is followed by a double lap crossing Lake Burley Griffin (over the Kings Avenue and Commonwealth Avenue bridges) and along Parkes Way out towards the Glenloch interchange, which is within close proximity to the Telstra Tower landmark.
Runners who complete 10 Canberra marathons are given the honorary title of Griffin, in reference to Lake Burley Griffin, which is at the centre of the marathon and the city of Canberra. The marathon is small in comparison to other big city races with just 866 people completing the 2006 event.
