Why we Taper for a Marathon

Chelmsford Physio • March 25, 2024

Preparing for a marathon is a physically and mentally demanding task. As the race day approaches, runners often implement a strategic training technique known as tapering. Tapering involves reducing the training load and allowing the body to recover in the weeks leading up to the marathon. But why do we taper? In this blog post, we will explore the scientific rationale behind tapering and why it is an helpful component of marathon preparation


1. Enhancing Physical Recovery:

Tapering provides an opportunity for the body to recover and repair. Intense marathon training places considerable stress on the musculoskeletal system, causing microscopic damage to muscles, tendons, and other connective tissues. By tapering, runners allow these tissues to heal and adapt, reducing the risk of injury and improving overall performance.


Tapering can help restore glycogen stores in muscles, improve muscle strength, and increase the concentration of enzymes involved in energy production. These physiological changes contribute to enhanced athletic performance on race day.

2. Reducing Fatigue and Overtraining:

Overtraining is a common concern among marathon runners. Pushing the body too hard without adequate recovery can lead to excessive fatigue, decreased performance, and even burnout. Tapering allows the body to replenish its energy stores, reduce accumulated fatigue, and restore hormonal imbalances caused by intense training.


Many studies suggests that tapering can help decrease muscle damage and inflammation markers, such as creatine kinase, C-reactive protein, and interleukin-6. These findings indicate that tapering plays a vital role in reducing the risk of overtraining syndrome, optimising recovery, and maximising performance potential.


3. Improving Psychological Readiness:

Marathon training is not just physically demanding; it also takes a toll on the mind. The mental aspect of running a marathon is crucial, as it requires focus, determination, and resilience. Tapering provides runners with an opportunity to recharge mentally, reducing stress and anxiety associated with intense training.


Research reports tapering can improve sleep quality, reduce psychological stress, and enhance overall well-being. Adequate rest during the tapering period helps runners feel fresh, motivated, and mentally prepared for the challenges of the marathon.

4. Maintaining Fitness Gains:

One might worry that reducing training volume during the tapering phase could lead to a decline in fitness. However, scientific evidence suggests otherwise. Tapering does not result in a loss of fitness; rather, it allows the body to consolidate the gains made during training.

 

Research has demonstrated that tapering can help maintain endurance while reducing training-related fatigue. The study found that runners who tapered adequately before a marathon maintained their cardiovascular fitness and experienced improved running economy.



Tapering is a scientifically supported strategy that plays a vital role in marathon preparation. By reducing training volume, allowing physical recovery, minimising fatigue, enhancing mental readiness, and consolidating fitness gains, tapering optimises performance potential on race day.

 

Research has shed light on the physiological and psychological benefits of tapering, emphasising its importance in preventing overtraining, reducing injury risk, and achieving peak performance. As you embark on your marathon journey, remember to incorporate a well-structured tapering phase into your training plan. It might just be the key to reaching your full potential and crossing that finish line with a smile.

In modern physiotherapy, clinical expertise remains fundamental, but technology is transforming how we assess, monitor and guide rehabilitation. One of the most valuable innovations is the use of force plate technology, and at our clinic we utilise the VALD ForceDecks to provide objective, reliable data throughout a patient’s rehabilitation journey. Rather than relying solely on observation or subjective feedback, ForceDecks enable us to accurately measure how your body produces and absorbs force. This allows us to identify movement deficits that may not be visible to the naked eye, track progress over time, and make evidence-based decisions regarding exercise progression and return to activity. What are VALD ForceDecks? VALD ForceDecks are dual force plates that measure the forces generated through the feet during a wide variety of movements. Using highly sensitive load cells, they capture detailed information about strength, balance, power, asymmetries and movement strategies. Common assessments include: Countermovement jumps Squat assessments Single-leg balance testing Sit-to-stand testing Isometric strength testing Landing mechanics Hop testing for return-to-sport decisions Within seconds, the software analyses hundreds of metrics that provide clinicians with objective insight into a patient’s physical performance. Why Objective Assessment Matters Traditional physiotherapy assessments rely on observation, manual muscle testing and patient-reported symptoms. Whilst these remain valuable, they can miss subtle deficits that increase the risk of delayed recovery or re-injury. ForceDecks allow physiotherapists to quantify movement rather than estimate it. For example, following an ACL reconstruction, a patient may appear to squat evenly. However, ForceDecks often reveal significant offloading of the surgical limb, reduced eccentric control or delayed force production. These hidden compensations can then become specific treatment targets. Objective measurements also improve communication between clinician and patient. Seeing measurable improvements in strength or symmetry provides reassurance that rehabilitation is progressing, even when symptoms fluctuate. Monitoring Progress with Precision One of the greatest benefits of ForceDecks is the ability to track rehabilitation over time. Instead of simply asking whether someone feels stronger, we can measure improvements in: Peak force production Limb symmetry Rate of force development Jump height Landing forces Balance performance Weight distribution This enables rehabilitation programmes to be progressed based on measurable performance rather than arbitrary timelines. Improving Return-to-Sport Decisions Returning to sport too early remains one of the biggest risk factors for re-injury. Research has consistently demonstrated that persistent strength deficits and movement asymmetries can remain long after pain has resolved. ForceDecks help clinicians identify these deficits before an athlete returns to competition. Objective testing can assist with: Assessing readiness to return to running Evaluating landing mechanics Measuring explosive power Identifying left-right asymmetries Monitoring fatigue Reducing the risk of subsequent injury Rather than relying on a single test, ForceDecks contribute to a comprehensive return-to-performance assessment that combines physical capacity with clinical reasoning.

On 23 and 24 October, I represented Chelmsford Physio at VALDCon London, held at Lord's Cricket Ground. VALD makes the ForceDecks force plates and DynaMo dynamometer we use in clinic to measure strength, power and left-right balance. The two days brought together physios and sports scientists from elite sport, including England cricket, British Athletics and professional football. They shared how they use testing to guide rehab and return to sport. Here are the takeaways most relevant to you, and how we're bringing them into the clinic.
