Downhill Running Technique for Trails and Fells
Descending is where trail races are won and where most injuries happen. It is also the most trainable skill in the sport, and the one almost nobody practises.
Most runners lose more time on descents than they ever gain on climbs, because braking with every step is exhausting and slow. Good descending is about letting gravity do the work while keeping your feet underneath you.
None of this requires bravery. It requires a shorter stride, a higher cadence and eyes looking further ahead than feels natural.
The five things that change everything
- Look ahead, not down. Scan 4–6 m in front. Your feet handle what your eyes have already processed.
- Increase cadence, shorten stride. Quick light steps. Long reaching strides land you heel-first with the brakes on.
- Land under your body. Every foot placed in front of your hips is a braking force through the knee.
- Stay tall and let the hips fall down the slope. Leaning back is the instinct and it's what makes people slip.
- Use your arms wide for balance. They're a stabiliser, not decoration.
By surface
| Surface | How to run it |
|---|---|
| Steep wet grass | Heels dug in on the steepest bits, short steps, aggressive lugs are essential |
| Rocky path | Look further ahead, plant on flat surfaces, avoid the edges of embedded rock |
| Scree | Where it's live and deep, let each step slide. Never on fixed or vegetated scree |
| Peat and bog | Aim for tussocks and heather, not the black stuff between them |
| Wet rock and roots | Step over, never on. Cross roots at right angles |
| Stone-pitched path | Hardest on the quads — shorten stride and accept it will be slow |
Training your legs to take it
Downhill running is eccentric loading — your quads absorb force while lengthening, which is what causes the deep soreness two days later. You cannot fake this fitness on the flat. Build it with short, repeated descents at moderate speed, and progress slowly; the damage accumulates faster than your perceived effort suggests.
- Descent repeats — 5–8 × 60 seconds down a moderate slope, jog back up
- Technical practice — one weekly run on deliberately awkward ground at easy pace
- Eccentric strength — slow-lowering split squats and step-downs
The mental part
Hesitation is what causes falls. A runner who commits to a line with a short, quick stride is far safer than one who half-brakes and shuffles. Build the commitment on ground where a mistake costs nothing — a grassy slope, not a rocky one — and take it upwards in difficulty from there.
Frequently asked questions
How do I stop my quads hurting after descents?
Build downhill volume gradually and train the eccentric strength directly with slow step-downs and split squats. Shortening your stride and increasing cadence also reduces peak force per step substantially.
Should I lean forward or back going downhill?
Stay upright with a very slight forward lean from the ankles. Leaning back puts you on your heels, which is exactly how people slip on wet grass.
What shoes are best for steep descents?
Aggressive lugs of 5 mm or more for soft British ground, and a shoe that holds your foot securely so your toes aren't jamming forward on every step.
