Salisbury East is about twenty kilometres north of the city, and part of Cobbler Creek Recreation Park falls inside its boundaries.
Trail is a different sport to road. That is the single most useful thing to know about training out here. Uneven ground, loose surface, roots, rocks and gradient mean the ankle and foot are constantly making small corrections that never happen on a footpath, and the load through the calf and Achilles varies with every step rather than repeating cleanly.
For a prepared body that is excellent. It builds genuine robustness. For a body that has only ever run on flat sealed surfaces, the first few months of trail running produce a reliable crop of rolled ankles, Achilles complaints and lateral knee pain.
The rolled ankle is the one most often dismissed. It gets rested for a fortnight, feels fine, and goes back to trail without ever regaining the balance and strength it lost. That is why the second sprain arrives, and the third, and why some people end up with an ankle they simply do not trust on uneven ground years later. It is fixable, including well after the fact, but it needs actual rehab rather than time.
Cobbler Creek also brings mountain bikers, and the injury profile there is different again: shoulders and wrists from coming off, plus lower backs from sustained flexion.
Salisbury East is one of the longer trips in my catchment, around eighteen minutes, so it is worth being clear that people generally come this far for a specific approach rather than proximity.
