Uneven Surface Run: Trail Drills and Speed Work

Session Overview

This 45-minute outdoor session takes your speed work off the roads and onto uneven terrain — grass, gravel, and trail surfaces. Running on variable ground fires smaller stabilising muscles, improves proprioception, and builds the ankle strength needed for technical race courses.

What You’ll Need

• Trail shoes or road shoes with grip
• Suitable location: park, trail, or grassy area
• GPS watch
• Water bottle

Warm-Up (10 minutes)

Jog 5 minutes easy on flat ground, then move to a grassy area for dynamic drills: high knees (20m), butt kicks (20m), lateral shuffles (2 x 10m each direction), and quick feet (2 x 10m). Finish with 3 x 20m strides building to 80% effort on grass.

Main Set

The main set is 5 rounds of a 4-minute effort on uneven surface, with 90 seconds of active walking recovery between each rep. Each round should feel like an RPE 7–8 — harder than a tempo but not an all-out sprint.

• 5 x 4-minute trail efforts at RPE 7–8, on grass, gravel, or mixed terrain
• 90 seconds brisk walking between each rep
• Focus on short, quick strides on technical sections — avoid over-striding on uneven ground
• Optional: include 2 short uphill sections in your loop for added strength stimulus

Cool-Down (5 minutes)

Return to flat ground for a 5-minute easy jog, then spend 3 minutes stretching calves, hip flexors, and hamstrings. Pay particular attention to the tibialis anterior (shin) which works hard on uneven ground.

Coaching Notes

• Look 2–3m ahead on trail sections, not at your feet — this improves your proprioceptive response
• Relax your arms and let them naturally counterbalance over rough patches
• For beginners, start with 3 reps and build to 5 as confidence grows
• Target heart rate: Zone 3–4 during efforts; Zone 1 during walk recovery
