Marathon Training Injuries London: 7 Ways to Stay Race-Ready

Sara Mather · 11 March 2026

Marathon training injuries are common in the final 6 to 8 weeks before race day.

If you’re building mileage around Hexham, the Tyne Valley paths or local hill routes, this is the stage of training where small niggles often start to appear.

Tight calves.
Achilles soreness in the morning.
A knee that aches after long runs.
A hamstring that doesn’t feel quite right.

This is common especially as mileage increases. But it’s also the point where small irritations can escalate if they’re ignored.

The goal isn’t to panic.

It’s to understand what your body needs at this stage of training.

Why Marathon Training Injuries Spike 6 to 8 Weeks Before Race Day.

Around this point in a marathon plan:

  • Weekly mileage increases
  • Long runs extend beyond 90 minutes
  • Fatigue accumulates
  • Strength training often reduces
  • Recovery time gets squeezed

Your cardiovascular fitness improves faster than your tendons adapt.

Muscles respond relatively quickly to training. Tendons adapt more slowly.

When mileage builds faster than tissue adaptation, irritation develops.

This doesn’t mean you’re “injured”  it means your body is asking for smarter load management.

The Most Common Marathon Training Injuries We See

In clinic, these are the patterns we commonly assess in runners preparing for London:

Achilles Tendinopathy

Morning stiffness, soreness that improves during the run but worsens later.

Patellofemoral Knee Pain

Pain around or behind the kneecap, especially on hills or stairs.

IT Band Irritation

Outer thigh or knee pain during longer runs.

Proximal Hamstring Tendinopathy

Deep buttock pain, often worse after sitting or uphill running.

Plantar Fasciitis

Heel pain, particularly first thing in the morning.

Many runners assume these mean they must stop training entirely.

In most cases, that’s not necessary.

Warning Signs You Shouldn’t Ignore

Some discomfort during marathon training is expected. But certain patterns suggest you need to adjust:

  • Pain that progressively worsens during a run
  • Morning stiffness that’s increasing week by week
  • Changing your running style to avoid pain
  • Needing painkillers to complete long runs
  • Pain lasting more than 7–10 days

These are signals that your tissues are struggling to keep up with load.

Early adjustment is far more effective than pushing through until race day feels at risk.

A Simple “Mid-Block Reset” If Niggles Are Appearing

If you’re noticing persistent soreness, try:

  • Reducing mileage by 15–20% for 5–7 days
  • Reintroducing two short strength sessions weekly
  • Prioritising sleep and fuelling
  • Rotating shoes if you’ve increased mileage significantly
  • Avoiding sudden hill or speed spikes

Short-term adjustment often prevents long-term disruption.

You rarely lose fitness in a week but you can gain resilience.

Marathon Training After 40. What Changes?

If you’re over 40, recovery may feel different compared to earlier years.

This is not about decline, it’s about adaptation.

With age:

  • Tendons adapt slightly more slowly
  • Recovery requires more intention
  • Strength work becomes more important
  • Sleep quality matters more

Many runners reduce strength training as mileage increases.

But this is often the stage where strength becomes most protective.

Progressive loading  not complete rest is what keeps tissues robust.

Should You See a Physio Before Race Day?

You don’t need an appointment for every ache.

But it’s worth booking an assessment if:

  • Pain is limiting your long runs
  • You’re worried about making the start line
  • Symptoms keep returning despite adjustments
  • You’re unsure whether to push or pull back
