Marathon Training: The Final Countdown
Marathon Training: The Final Countdown
By Professor Greg Whyte OBE PhD DSc FBASES FACSM
The final weeks prior to the marathon can be the most problematic when it comes to injury and illness, particularly for first timers. Training volume should increase progressively throughout the training programme; however, it is during the final few weeks when training volume hits its peak.
It is important to remember that volume is not simply associated with the duration (distance) of runs. Volume is the product of duration (how long), frequency (how often) and intensity (how hard). In addition to increased duration of runs in the later stages of training, the intensity and frequency of runs increases.
The combined effect of this increased volume is escalating fatigue, which increases the risk of injury and illness if appropriate steps are not taken.
Injury Risk in the Final Weeks of Marathon Training
Injuries in the later stages of training include damage to muscles, connective tissue and joints of the lower extremities. Common injuries include Achilles tendinopathy, plantar fasciitis, tibial stress syndrome (shin splints) and patellofemoral pain syndrome (runner’s knee).
Whilst increasing training volume prior to tapering (usually 1 to 2 weeks of reduced training volume prior to the marathon) is an important part of marathon preparation, it is important to optimise recovery to reduce excessive fatigue, and maintain strength, flexibility and mobility training throughout the programme.
Recovery plans should include a focus on:
- Nutrition
- Hydration
- Stress reduction
- Rest and sleep
Given the common soft tissue injuries (muscle and tendon) associated with marathon training, optimising protein intake, including the type, timing and quantity of protein, is critical to support repair and regeneration.
Whey protein and collagen are central to optimising soft tissue recovery as training volume increases.
Supporting Your Recovery: Active Whey & Collagen
Whey protein supports the repair and rebuilding of muscle following training. During marathon preparation, muscle tissue is repeatedly broken down, and adequate protein intake is essential to support recovery and adaptation.
Collagen is the key structural protein found in tendons, ligaments and cartilage. These tissues take longer to recover than muscle and are placed under repeated stress during running.
Active Whey & Collagen combines both — supporting muscle recovery while also providing targeted support for connective tissue, including tendons, ligaments and joints.
As training volume increases in the final weeks before a marathon, supporting both muscle and connective tissue becomes increasingly important to maintain consistency and reduce the risk of injury.
Avoiding Illness Before Race Day
Avoiding illness in the final countdown to the marathon is also crucial. The increased training volume and concomitant fatigue, combined with the increased psychological stress as race day approaches, are a common recipe for illness.
Maintaining euhydration (normal hydration), alongside a healthy balanced diet and alcohol reduction or avoidance, is important in reducing the risk of illness.
Furthermore, lifestyle factors play an important role in illness reduction. Avoiding people with illness and large crowds, together with personal hygiene, including regular washing of hands and avoiding contact with eyes, nose and mouth, will reduce exposure to pathogens.
Optimising sleep (quality and quantity) will provide the much-needed time to enhance recovery and will help reduce the risk of illness.
The Importance of Recovery in Marathon Preparation
Whilst injury and illness are common in the later stages of marathon training, they are not inevitable.
The importance of planning training is well recognised, but planning recovery is just as important. This should encompass a range of approaches including:
- Nutrition and hydration
- Lifestyle modification
- Sleep optimisation
Getting recovery right will reduce the risk of injury and illness and enhance marathon day performance.
Supporting Your Marathon Preparation
The final weeks of marathon training place increased stress on your body. As training volume rises, so does fatigue and with it, the risk of injury and illness.
Supporting your recovery, joints and overall health during this phase is essential to maintain consistency and arrive at race day in the best possible condition.
The U Perform Marathon Bundle is designed to support your training and recovery across every stage:
- Active Collagen (3 x) – Provides 8,000mg of Bioactive Collagen Peptides® to support tendons, ligaments and muscle recovery
- Active Greens (1 x) – 16 superfoods, adaptogens and probiotics to support energy, immunity and overall health
- U Perform Bottle (Free) – For easy daily use and staying hydrated on the go
- Guide to Marathons (Free) – Expert advice from Professor Greg Whyte OBE on training, recovery and performance
By supporting both recovery and overall health, the bundle is built to help you train consistently, reduce setbacks and stay on track.
Marathon Training FAQs
Why is the final phase of marathon training high risk?
Training volume peaks in the final weeks, increasing fatigue and the risk of injury and illness if recovery is not optimised.
What injuries are common during marathon training?
Achilles tendinopathy, plantar fasciitis, shin splints and runner’s knee are common, affecting muscles, joints and connective tissue.
What does training volume mean?
It is the combination of duration (how long), frequency (how often) and intensity (how hard).
How can I reduce injury risk?
Prioritise recovery: nutrition, hydration, strength work, mobility, stress management and sleep.
Why is protein important for runners?
Protein supports the repair of muscle and connective tissue. Whey protein and collagen help support recovery as training load increases.
How can I avoid illness before race day?
Stay hydrated, eat well, reduce alcohol, practise good hygiene and prioritise sleep.
What is tapering?
A 1–2 week reduction in training volume before race day to allow recovery while maintaining fitness.
Is injury inevitable during marathon training?
No. With proper recovery and planning, risk can be reduced.
