Possibly The Single Most Important Exercises for Any Marathon Runner

Chelmsford Physio • January 12, 2026

Marathon running is a test of endurance, strength, and mental fortitude. For runners preparing for this challenge, focusing on specific muscle groups is essential for optimal performance and injury prevention.


Among these, the calf muscles play a pivotal role. In this blog, we will explore the most effective calf exercises for marathon runners. 


Understanding the Role of Calves in Running


Before delving into the exercises, it's crucial to understand why calf strength is vital for marathon runners. Your calf complex muscle will absorb an internal force of up to 8x your body weight on every step you take when running.


Strengthening these muscles ensures better endurance and reduces the risk of injuries such as calf strains or Achilles tendonitis.




Key Calf Exercises for Marathon Runners


1) Seated Calf Raise


The seated calf raise targets the soleus muscle, a vital component for long-distance running.


How to Perform:



  • Start with 3 sets of 10-12 reps with both legs.
  • As you build strength, aim for 20 reps.
  • Once achieving this, progress to single-leg raises to intensify the exercise.



2) Standing Straight Knee Calf Raise


This exercise focuses on the gastrocnemius muscle, crucial for explosive movements.


How to Perform:



  • Begin with 3 sets of 10-12 reps using both legs.
  • Work up to performing 20 reps.
  • Then, move to single-leg raises for a more challenging workout.



3) Standing Bent Knee Calf Raise


The standing bent knee calf raise also targets the soleus muscle but in a different position, offering a comprehensive muscle workout.


How to Perform:



  • Start with 3 sets of 10-12 reps using both legs.
  • Progress to 20 reps.
  • Then, transition to single-leg raises for increased intensity.



4) Loaded Toe Walks


Loaded toe walks help improve balance and strength in the calves.


How to Perform:



  • Choose a challenging weight.
  • Aim for 30 steps, 15 with the right leg and 15 with the left, moving slowly.
  • Repeat for 3 rounds.



5) Isometric Calf Hold on Leg Press


Isometric exercises are excellent for building strength and endurance.


How to Perform:


  • Find a challenging weight on the leg press.
  • Hold your heel off the plate for 6-8 seconds.
  • *Perform this on 3-4 times on both sides, alternating from left to right.
  • Repeat for 3 rounds.



Tips for Effective Training:


  • Progress Gradually: Avoid overexertion by gradually increasing reps and intensity.
  • Consistency is Key: Regularly perform these exercises to see improvements.
  • Listen to Your Body: If you experience pain beyond normal muscle fatigue, rest and seek professional advice.


Combining Exercises with Overall Marathon Training


While calf exercises are crucial, they should be part of a broader training plan that includes cardio, strength training, flexibility exercises, and adequate rest. Balancing these elements is essential for a holistic approach to marathon preparation.


Maybe look to work on 2/3 of the exercises above in a strength session. Aim for 2 strength sessions per week, with additional exercises for other muscle groups.


When to Seek Professional Help


If you're experiencing persistent pain or have concerns about your training regimen, professional guidance can be invaluable. At Chelmsford Physio, we're equipped to assist with tailored advice and physiotherapy treatment.


Conclusion


Strengthening your calves is a crucial aspect of marathon preparation, offering benefits in endurance, speed, and injury prevention. By incorporating these exercises into your routine, you can significantly enhance your running performance.


Remember, each runner's body is unique, and what works for one may not work for another. Therefore, it's essential to tailor your training to your individual needs and capabilities.

How Athletes Adapt Their Training to Cope with High Temperatures: The Science of Heat Acclimatisation

By Chelmsford Physio • July 29, 2026
Athletes competing in hot and humid environments face significant physiological challenges that can impair performance and increase the risk of heat-related illness. From marathon runners in tropical climates to footballers playing summer tournaments, the ability to tolerate and perform in high temperatures is a critical component of elite sport. As a result, many athletes use structured heat acclimatisation strategies to prepare their bodies for environmental stress.  What Is Heat Acclimatisation? Heat acclimatisation refers to a series of physiological adaptations that occur when an athlete is repeatedly exposed to hot conditions during training. These adaptations typically develop over 7–14 days and help the body improve its ability to regulate temperature, maintain performance, and reduce cardiovascular strain during exercise in the heat. Common methods include: ● Training in hot environments (natural or artificial heat chambers) ● Passive heat exposure (saunas or hot water immersion post-training) ● Adjusting clothing to increase thermal load during sessions ● Gradual exposure to increased environmental temperatures The goal is to safely stress the thermoregulatory system so the body becomes more efficient at dissipating heat.

Why Footballers & Athletes Use Ice Baths: The Science Behind Cold Water Immersion

By Chelmsford Physio • July 29, 2026
Ice baths, also known as cold water immersion (CWI), have become a common recovery strategy among elite athletes, particularly footballers. From Premier League changing rooms to Olympic training camps, many professionals immerse themselves in cold water after intense matches and training sessions. While the sight of players sitting in freezing water may seem extreme, there is growing scientific evidence explaining why this recovery method is so widely used. What Is an Ice Bath? An ice bath typically involves immersing the body (or lower limbs) in water between 10–15°C for 10–15 minutes shortly after exercise. The aim is to promote recovery by reducing muscle soreness, inflammation and fatigue, allowing athletes to perform consistently during periods of heavy training or competition. Why Do Footballers Use Ice Baths? Football is a physically demanding sport involving repeated sprinting, jumping, tackling, rapid changes of direction and high-impact collisions. These actions create microscopic muscle damage and trigger an inflammatory response. Cold water immersion is commonly used because it may help: ● Reduce delayed onset muscle soreness (DOMS) ● Minimise post-exercise swelling ● Decrease perceptions of fatigue ● Improve recovery between matches ● Maintain performance during congested fixture schedules For professional footballers playing two or three matches per week, rapid recovery is often as important as training itself. 

The Physio’s World Cup Playbook: Most Common Injuries at FIFA World Cup 2026 (and What to Do About Them)

By Chelmsford Physio • July 29, 2026
The FIFA World Cup is a unique tournament environment: elite athletes compressed into a short, high-stakes schedule, with repeated sprinting, sudden acceleration/deceleration, frequent collisions, and often limited time for full tissue recovery. It’s not surprising that the injury pattern in football tends to cluster around the lower limb—particularly the hamstrings, groin/hip-adductors, knee, and ankle. Across football research more broadly, these are repeatedly identified as the most common locations and/or injury mechanisms, even if the exact percentages differ by competition and injury-reporting method. Below is a physio-focused overview of the most common injury “types/regions” you should expect to see at World Cup 2026, along with practical assessment and management themes. 1) Muscle strains—especially hamstrings (HSI)  Why they happen in tournaments: Hamstring strain injuries (HSIs) are strongly associated with high-speed running and the physical demands of sprinting mechanics. In injury surveillance and football epidemiology, hamstring injuries consistently appear among the most common soft-tissue problems, with meaningful recurrence risk. What a physio will look for: - History: onset during acceleration/sprinting, feeling of “pull,” bruising (sometimes). - CNS/tissue considerations: prior injury, training load spikes, inadequate sprint exposure progression. - Clinical exam: focal tenderness, resisted muscle testing, and functional tests aligned to your local protocols (e.g., pain-free activation and lengthening tolerance). Rehabilitation themes: - Restore capacity for high-speed eccentric/concentric demands (not just range of motion). - Use progressive loading and functional return-to-play criteria to address reinjury risk—because football research highlights that the hamstring is one of the most frequently reinjured regions.
