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>.
