Marathon Taper: What to Do About Niggles Before Race Day

Why the Taper Can Feel Uncomfortable


The taper can be an unexpectedly stressful period for runners. Training volume drops, recovery becomes a bigger priority, and every small ache can suddenly feel more noticeable. At the same time, runners sometimes introduce last-minute changes — new shoes, extra stretching, gym sessions or altered running routes — that can create unnecessary load right before race day.




Common Running Injuries During Marathon Taper


  • Shin pain / shin splints (medial tibial stress syndrome) — may become noticeable when training load, running surface, pace or footwear changes. Pain that is very localised, progressively worsening, or painful when walking should be assessed rather than assumed to be ordinary shin splints
  • Achilles pain or irritation — can be aggravated by speed work, hills or sudden changes in training load, even during a reduced-volume taper
  • Patellofemoral (knee) pain — often resurfaces as training rhythm and running mechanics change through the taper
  • Plantar heel/foot pain — can be aggravated by changes in footwear, training load or running volume
  • Calf and hamstring tightness — commonly linked to reduced overall training volume combined with maintained intensity



  • Is It a Niggle or an Injury?


    Not every ache during taper means you need to stop running. Mild muscle soreness or stiffness that settles as you warm up, and doesn't affect your running mechanics, may be manageable with some load modification.


    Pain that becomes progressively worse, changes your stride, remains significant after running, causes swelling, or is becoming more localised deserves more attention. If you are unsure whether to continue training, an individual assessment is more useful than trying to self-diagnose.




    What to Do at 3 Weeks, 2 Weeks and Race Week


    3 weeks before race day

  • Begin reducing training volume according to your planned marathon programme
  • Maintain some faster running if it is already part of your programme
  • Don't introduce new strength exercises, shoes or major changes to your running routine
  • Prioritise recovery between sessions

  • 2 weeks before race day

  • Continue the planned reduction in mileage
  • Don't try to compensate for missed training
  • Address persistent pain rather than repeatedly testing it with runs
  • Keep sleep, nutrition and hydration consistent

  • Race week

  • Follow your established race-week plan
  • Keep running short and easy where appropriate, with rest or a very light shakeout as your plan indicates
  • Avoid last-minute "fitness tests"
  • Avoid experimenting with aggressive massage, unfamiliar treatment or intense stretching immediately before race day — if sports massage is already part of your routine, discuss timing and intensity with your physiotherapist

  • Ideally, race in footwear you have already tested successfully on longer training runs. Avoid making a major footwear change immediately before race day.




    When Should You Stop Running?


    Don't try to run through these symptoms — seek prompt assessment if you develop:


  • Significant or rapidly increasing swelling
  • Inability to bear weight normally
  • Severe or focal bone pain
  • Pain that changes your running gait
  • Significant pain at rest or at night
  • Sudden loss of strength
  • Numbness or altered sensation
  • A sudden "pop" followed by significant pain or weakness



  • When Should You See a Physiotherapist Before a Marathon?


    Running the Dublin Marathon? Don't wait until race week to get a persistent niggle assessed. A pre-race assessment can help determine whether the problem is responding to load modification, whether you need to adjust your final sessions, and what symptoms should influence your race-day decision. Our physiotherapists in Santry and Swords see runners through exactly this decision every taper season.




    How Physiotherapy Can Help Before Race Day


  • Assessment to distinguish normal taper fatigue from a developing injury
  • Targeted manual therapy for tight or overloaded areas
  • Taping and strapping advice for race day
  • Guidance on load management through the final taper weeks



  • Marathon Taper Injury FAQs


    Can I run a marathon with a minor injury?

    Sometimes, depending on the injury. Mild, non-progressive discomfort that doesn't change your mechanics may be manageable, but anything worsening or affecting your stride should be assessed before race day.


    Should I stop running if I develop pain during taper?

    Not necessarily — but pain that is sharp, localised, worsening, or changes how you run is a signal to get it checked rather than push through.


    How long before a marathon should I see a physiotherapist?

    As soon as a niggle appears rather than waiting for race week — the earlier it's assessed, the more options there are to manage it before race day.


    Should I get a massage during marathon taper?

    If it's already part of your regular routine, that's generally fine — timing and intensity matter more than whether to have one at all. Avoid trying massage for the first time right before the race.


    Is it safe to change running shoes before a marathon?

    Best to race in shoes you've already tested on longer training runs. Avoid switching to unfamiliar footwear right before race day.


    Can physiotherapy help if I develop a niggle one week before the marathon?

    Yes — even a short window before race day can be enough for assessment, targeted treatment, and taping or load-management advice to help you start the race in better shape.
