The Final Month Before Your Marathon: Stay Healthy, Taper Smart, Perform Your Best

The final month before a marathon is where many runners unknowingly make their biggest mistakes. After months of consistent training, it’s natural to feel the urge to push harder, but this is the phase where smarter, not harder, wins. From a physiotherapy perspective, this period is less about building fitness and more about protecting it. Managing load, respecting recovery, and addressing small issues early can make the difference between arriving at the start line feeling strong, or not making it there at all.

1 - Respect the Taper

Many runners worry that reducing mileage will cause them to lose fitness.

Physiologically, that’s very unlikely.

The taper allows:

• Muscle fibres to repair

• Glycogen stores to replenish

• Cumulative fatigue to reduce

• Small niggles to settle

Reducing weekly mileage by around 20–30% each week while maintaining some intensity helps you arrive at the start line fresh rather than fatigued.

This reduction in load is also important for reducing the risk of overuse injuries such as:

• Achilles Tendinopathy

• Patellofemoral Pain

• Medial Tibial Stress Syndrome (shin splints)

2 - Listen to niggles early

One of the biggest mistakes runners make in the final month is ignoring pain

because the race is close.

A simple rule I often share with runners is, pain that; changes your running form, gets worse during the run, persists the next day… is worth addressing early.

Minor symptoms caught early can often be managed with:

• Temporary load reduction

• Mobility work

• Targeted strengthening

• Short-term cross-training

Ignoring them can turn a small issue into something that jeopardises race day entirely.

3 - Maintain Strength but reduce volume

Strength training is still valuable in the final month, but the focus should shift to maintenance rather than progression.

Runners benefit from keeping exercises that support:

• Hip stability

• Calf strength

• Single-leg control

Examples include: single leg calf raises, split squats, glute bridges, step downs

Reducing sets or frequency slightly can maintain neuromuscular control while

avoiding unnecessary fatigue.

4 - Prioritise Recovery

Training adaptations happen during recovery, not just during the run.

In the final month, recovery strategies become even more important:

• Sleep: Aim for consistent, high-quality sleep

• Nutrition: Support recovery with adequate carbohydrate and protein

• Mobility work: Light stretching and mobility for hips, calves, and hamstrings

• Self-management: Foam rolling or massage where helpful

• Booking sports massage treatments

Runners often underestimate how much improved recovery can reduce injury risk and improve performance.

5 - Avoid Last Minute Changes

Physiotherapists frequently see injuries caused by sudden changes in training or equipment close to an event.

Common examples include:

• New running shoes

• Changes in running form

• Adding extra training sessions

• Introducing unfamiliar strength exercises

The final month is not the time to experiment. Stick with what your body has already adapted to.

6 - Practice your Race Day Routine

From an injury-prevention perspective, rehearsing race-day routines can help reduce unexpected stress on the body.

During your final long runs, practice:

• Your warm-up routine

• Fuelling strategy

• Clothing and footwear

• Race pace

Consistency reduces surprises and helps your body perform in a familiar and

predictable way.

7 - Manage Taper Anxiety

It’s extremely common for runners to feel restless or worried when training volumedrops.

Many athletes report feeling:

• Sluggish

• Heavy-legged

• Concerned about losing fitness

This is normal and usually resolves once race day arrives.

A useful mindset shift is remembering that fitness has already been built — the taper simply allows it to be expressed.

The Goal - Arrive Healthy

From a physiotherapy perspective, the most important goal of the final month is simple:

Arrive at the start line healthy and confident.

If you're heading into your marathon and want to make sure you're fully prepared, we’re here to help. Whether it’s managing a niggle, refining your strength work, or building confidence before race day, a tailored physiotherapy assessment can help you arrive at the start line feeling your best.
