Strength Training for Ultrarunning on Australian Trails

Ultrarunning asks the body to produce useful force long after ordinary fatigue has arrived. The limiting factor is rarely the ability to run quickly for a few minutes. It is the capacity to keep climbing, descending, stabilising and moving efficiently when the legs are tired, the terrain is uneven and the next aid station is still a long way off.

Strength training gives that endurance a stronger chassis. It can improve running economy, protect connective tissue, support climbing power and make late-race movement less expensive. For Australian runners, the most effective approach also has to fit hot summers, hilly bush tracks, limited daylight in winter and the practical realities of fitting training around work and family.

Why Force Matters After Many Hours

Long races expose weaknesses that may remain hidden during ordinary weekly mileage. A runner can feel comfortable on flat paths but lose control on rocky descents, struggle to lift the knees late in a climb or develop lower-back discomfort as posture deteriorates. These problems often reflect fatigue in the muscles responsible for force production and joint control, rather than a simple lack of aerobic fitness.

A well-designed resistance programme improves the ability of the calves, quadriceps, hamstrings, glutes and trunk to share the workload. Stronger calves can help maintain ankle stiffness and push-off. Hip strength can support balance when a foot lands on a root or loose stone. A capable trunk helps the pelvis remain stable when fatigue encourages a shorter, less coordinated stride.

The benefit is also economic. If each step requires slightly less muscular effort, the runner can preserve glycogen and concentration for longer. This matters on courses such as the Blue Mountains Ultra-Trail, where sustained climbs and technical descents repeatedly interrupt an otherwise steady rhythm. Strength will not replace long runs, but it can help those long runs remain mechanically tidy.

Build Strength Around Running Load

Ultrarunners do not need a bodybuilder’s programme. They need enough strength to tolerate training and racing without creating soreness that compromises key runs. Two weekly sessions are usually sufficient during a foundation phase, while one maintenance session can work during peak mileage or a taper.

The first session can sit after an easy run, when the following day is not demanding. This arrangement groups stress together and leaves genuinely easier days available for recovery. A second session can be placed several days later, preferably away from the longest run. Australian athletes often train before work to avoid summer heat in Brisbane, Sydney or Perth, so the schedule should account for sleep and hydration rather than treating every early morning as free recovery.

Progress gradually. Add a small amount of load, one repetition or an extra set, but not all three at once. A useful working set should feel challenging while leaving roughly two controlled repetitions in reserve. Grinding to failure creates fatigue that has little value for an ultramarathoner and may disturb running form for several days.

A Practical Strength Menu

The best exercises are those that develop force through useful ranges of motion and can be performed consistently. A commercial gym is convenient, but a pair of adjustable dumbbells, a kettlebell, a step and a resistance band can cover most needs. Equipment prices vary widely in the Australian market, so a simple home setup is often more durable than buying a large collection of specialised machines.

A balanced session might include these movement patterns:

Single-leg work deserves particular attention because trail running rarely feels perfectly symmetrical. Step-downs, single-leg deadlifts and supported split squats expose balance problems without requiring extreme loads. Move slowly on the lowering phase, especially for exercises that prepare the quadriceps for long descents.

The programme should also include small but important supporting muscles. Two or three sets of each option are enough when performed consistently:

Hops and other plyometric exercises are useful only when the athlete already tolerates regular running and has no current injury. Begin with a small number of crisp contacts on a forgiving surface. Strength work should make the next week of running more reliable, not turn every staircase into a recovery test.

Test the Plan in Real Terrain

Gym strength is general preparation; trails reveal whether it transfers. After several weeks of consistent lifting, notice whether climbs feel more controlled, whether descents produce less soreness and whether posture remains stable late in a long run. A training log can record perceived effort, pace on a familiar hill and how the legs feel the following morning.

The most informative trials often happen on local terrain. Sydney runners can use bush tracks around the Northern Beaches or the Blue Mountains, while Melbourne athletes may find sustained gradients in the Dandenong Ranges. In Adelaide, the Mount Lofty area offers a useful mixture of climbs and uneven ground. These environments also demand attention to weather, loose surfaces and sudden changes in footing.

Heat changes the equation. During an Australian summer, a heavy lifting session followed by a long midday run can become a recovery problem even when the distances look reasonable. Early starts, shaded routes and conservative loading are sensible. State park closures, total fire bans and temporary track restrictions also need to be respected during bushfire season; a planned strength session indoors is preferable to forcing a trail workout when access is unsafe.

Race reports can provide a useful record of where muscular fatigue appeared and whether it matched training expectations. Comparing those observations with race reports from earlier events may reveal a recurring pattern: cramping after repeated descents, loss of climbing power or an inability to maintain posture in the final quarter. That evidence is more valuable than copying an elite athlete’s routine.

Make Strength a Durable Habit

The programme must survive busy weeks. A 25-minute session completed twice a week is more useful than an ambitious plan that disappears whenever work becomes demanding. Treat the sessions as part of the training system, alongside sleep, easy running, nutrition and mobility, rather than as optional extras added after the “real” workout.

Pain needs careful interpretation. Normal muscular effort and mild next-day stiffness are common when a new exercise is introduced. Sharp joint pain, worsening tendon symptoms or soreness that changes running mechanics calls for a reduction in load and, when necessary, assessment from a qualified professional. More strength is not automatically better strength.

Gear choices deserve the same practical judgement. Australian Consumer Law provides protections when fitness equipment is unsafe, faulty or not as described, but checking warranty terms, return conditions and product suitability still matters. A stable bench and well-made weights are worthwhile; expensive branding is not a substitute for an exercise plan that matches the runner’s needs.

A simple review every four weeks keeps the work connected to the bigger project. Note the exercises, loads, repetitions, running volume, soreness and any changes on hills. Keep what improves durability, remove what creates unnecessary fatigue and increase difficulty only when the current workload feels repeatable. This week, schedule two 25-minute sessions after easy runs and record the starting load for each exercise.
