The Knee Pain Mastery Guide
The Knee Pain Mastery Guide by Evolve Physio & Mastery is a structured knee rehabilitation program designed for athletes dealing with ACL, MCL, and meniscus injuries.
Ultras expose what wasn't prepared
Marathons and half marathons don't break runners at random. They expose what wasn't prepared — weak calves, under-conditioned tendons, spiky load increases, and skipped strength sessions. Whether you're targeting your first Sydney Marathon or a local half in Southwest Sydney, the injury prevention principles are identical. This is the same framework behind our 20-week ultra prep work — watch the full breakdown in our Running Masterclass.
The 16–20 week structure
- Weeks 1–4 (base): 3 runs/week, easy pace, establish 2× strength sessions. Total volume low — build habit.
- Weeks 5–10 (build): Add long run progressively (max +10% long run per week). Introduce one tempo or interval session.
- Weeks 11–16 (peak): Longest long runs (20–32 km for marathon; 16–18 km for half). Maintain strength.
- Weeks 17–20 (taper): Cut volume 20–40%, keep legs sharp with short efforts.

Strength non-negotiables (2×/week)
- Heavy single-leg calf raises (straight + bent knee): 3 × 8
- Bulgarian split squats or step-ups: 3 × 8 per side
- Single-leg RDL or hip hinge: 3 × 8
- Copenhagen adductor or side plank: 3 × 10
- Dead bugs / pallof press for trunk control
Load rules that prevent breakdown
- Never two hard days back-to-back
- Long run ≤30–35% of weekly volume
- One full rest or cross-train day per week minimum
- Sleep 7–9 hours — under-recovery is an injury risk factor
- Replace worn shoes every 600–800 km
Red flags during training block
- Shin or foot pain that worsens with running and persists next morning
- Localised hop pain (stress fracture screen)
- Knee pain that builds through a run — see runner's knee guide
- Calf pain after a sudden speed session — calf strain guide
Coming back from a training setback
If you've already lost weeks to injury mid-block, don't cram mileage. Use our 8-week return to running framework to rebuild safely, then adjust race expectations or defer. Finishing healthy beats a PB on a broken leg.
Book a running physio screen
A single pre-marathon movement screen catches load risk before it becomes a stress fracture. Book a running assessment at Evolve Physio & Mastery, Cabramatta. We prep runners from Liverpool, Fairfield, Bankstown and across Southwest Sydney.

Frequently Asked Questions
How much should I increase weekly mileage?
The 10% rule is a starting guideline — don't jump more than 10% week-to-week. Smarter still: track acute:chronic workload ratio (aim ~0.8–1.3). Spikes above 1.5 sharply increase injury risk.
Do I need strength training for marathon prep?
Yes — non-negotiable. Two sessions per week of heavy single-leg work (squats, deadlifts, calf raises, hip abduction) reduces running injury risk by roughly 50% in meta-analyses. Running alone doesn't build tendon and bone resilience.
What's the biggest mistake first-time marathoners make?
Building long-run distance too fast while skipping strength work and recovery. The long run shouldn't exceed ~30–35% of total weekly volume, and you need easy days between hard sessions.
When should I taper?
Standard marathon taper: 2–3 weeks. Reduce volume 20–40% while keeping some intensity sharp. Half marathon: 1–2 weeks. Don't take the taper as licence to stop entirely — short easy runs maintain neuromuscular readiness.
What pain means stop?
Pain that worsens during a run, persists into the next morning, or shifts location (compensation pattern) — stop and assess. Localised bone pain with hopping is a stress fracture red flag. See our <a href="/blog/stress-fractures-runners">stress fracture guide</a>.
