Loop the Mountains

From the Phillip Ave parking area, pick up the Ainslie Houses Track. Hang a left onto Ainslie Link Trail, then Socks Trail as it curves around the edge of the reserve. Just after 3 km, turn left onto Campbell Link Track and stick on this all the way until you meet the Telecom Trail, which is a wide and very runnable dirt road.

When you meet another road at about 7.5 km, turn uphill and follow the fenceline and footsteps of others until you hit another more defined trail at the top - turn right here and you're on Cherryburn Trail, which takes you downhill until you meet Blue Metal Rd at the top of the mountain bike park. Head down the road (the downhill MTB trails here are too dangerous to run down), then traverse along on Monterey Rd. Turn left off Monterey Road onto Betty Blue, then Mr Squiggle (these are also MTB trails, but are safer to run on. Still keep your ears out and give way to bikers, and stay on the road if you're not sure).

The end of these trails is a junction with a dirt road - cross it and pick up the walking trail, continuing uphill until you meet Mt Majura Road, which is sealed. Turn left and take this uphill for about 1.3 km until you reach the summit of Mt Majura. Pick up the trail that will take you down the opposite side, blast downhill for just under 1 km and then take a sharp right (at approx 15.5 km) - be careful not to miss this turn, as the trail continues straight ahead. The right-turn traverses you nicely around the contours - at 16km take the right at the fork, not the left/sharply down option - heading generally downhill until you reach Canberra Centenary Trail at the base of the hill.

Turn left and follow this main trail until you meet Hancocks Road - a right onto this will get you back to the start.
