Trail Running in Mount Lofty and the Adelaide Hills

The trail network around Mount Lofty is not one single climb but three very different kinds of running packed into a small area. Waterfall Gully to the summit is short, steep, and mostly stepped stone, the kind of pitch that punishes a runner who goes out too hard in the first kilometre. The Heysen Trail sections through Mylor and Bridgewater are gentler singletrack through vineyard country, better suited to a steady tempo effort than a hill session. Cleland's fire trails sit in between, wide and runnable but still carrying real vertical gain over an 18 km loop. Choosing the right trail for the day matters more here than distance alone.

Runners who want more than a single out-and-back often link sections together, dropping off the summit via a different route than they climbed and picking up part of the Cleland Big Loop before finishing back near Waterfall Gully. The open grassy firebreaks that cut across sections of the park run faster than the rocky singletrack near the summit ridge, so pace naturally settles into surges rather than a flat rhythm. Creek-side gravel sections lower down stay shaded and cooler even on a warm afternoon, which is why many locals save the lower loops for the middle of the day and keep the exposed ridge running for morning or evening. Treating the network as building blocks rather than one fixed route is how regular users get variety without leaving the park.

Adelaide's trail running culture is built around Mount Lofty rather than just on it. Trail Running South Australia runs a regular Tuesday evening session out of Waterfall Gully, using the same climbs casual runners tackle on weekends as structured hill repeats. Many of those same trails feed into the Yurrebilla Trail, the route beneath the summit ridge that hosts the SA Road Runners Club's 56 km Yurrebilla Ultra each September, one leg of the state's Five 50s ultra series. Locals training for that race, or for bigger events interstate, treat the Waterfall Gully climb as their benchmark session, timing repeats to track fitness through winter and spring.

The Yurrebilla Ultra has run since 2009, and the trail itself was established back in 2003, which means the route locals train on today has stayed largely the same for two decades. Support stops along the way are aimed at first-time ultra finishers as much as at competitive runners, and the event is often described as a good entry point for someone attempting their first ultramarathon distance rather than a race reserved for specialists. That accessibility feeds back into how people use Mount Lofty day to day, casual trail runners building toward the Yurrebilla distance treat the shorter loops around Waterfall Gully and Cleland as stepping stones, gradually stringing them together into longer weekend runs before attempting the full 56 km in September.
