Survive mile 20. Finish stronger.
Marathon training breaks most runners down through injury or fading form, not fitness. We build the strength and durability work into your block so your legs hold up for the full 26.2 — without adding fatigue on top of your long runs.
Why marathon runners need more than mileage
High weekly mileage without supporting strength work is one of the most reliable routes to an overuse injury. The repeated impact of marathon training — thousands of foot strikes at increasing fatigue — demands muscular and tendon durability that running alone doesn't build fast enough. We design a strength block that runs alongside your marathon plan: heavier and higher-volume in the early base phase, tapering to short, sharp maintenance sessions as your long runs and marathon-pace work ramp up.
A strength plan that respects your training block
This isn't generic gym programming bolted onto your week. We look at your race date, your long run days, and your weekly mileage, then build sessions that: • Load the posterior chain and hips for repeated impact tolerance • Build single-leg strength to reduce ITB, knee and hip niggles • Include calf and Achilles-specific loading for late-race durability • Stay low-fatigue in peak weeks so your legs are fresh for key runs • Taper appropriately in race week Most marathon clients train with us twice a week, dropping to once a week during the heaviest mileage phase.
Off-season and base phase strength foundations
The biggest strength gains happen when your running volume is lowest — typically 12-16 weeks out or in your off-season. This is when we build genuine strength and address any imbalances, so that by the time marathon-specific sessions start, your body can absorb the load without breaking down.

Frequently asked questions
When should I start strength training for a marathon?
Ideally from the start of your base phase, 16-20 weeks out. Heavy strength work is best built while mileage is lower, then tapered in volume (not intensity) as your long runs and race-specific sessions take over.
Will lifting weights interfere with my marathon block?
Not if it's programmed properly. We drop to lower-volume maintenance strength sessions during peak mileage weeks, and cut it further in the taper — the goal is fresh legs on race day, not extra fatigue.
What does marathon-specific strength training actually involve?
Heavy compound lifts (squat, deadlift, hip hinge) for durability, single-leg strength for the repeated-impact demands of 26.2 miles, calf and tendon loading, and core/postural work to hold form when you're fatigued at mile 20.
Can strength training help me avoid hitting the wall?
Strength training itself won't fix fuelling issues, but improved running economy and muscular durability mean your form holds up for longer, which helps you maintain pace when fatigue sets in.
