Let’s dive in and help get you back on track, stronger than ever. 

Unraveling the Reasons: Why Does My Achilles Tendon Hurt After Running?


Achilles tendon pain, including tendinitis and tendinosis, is often the result of a complex mix of genetic predispositions, poor training habits, and insufficient recovery. 

Understanding the underlying causes is crucial for effective prevention and treatment.

Let's break it down further:

Genetic Predispositions

The genes you inherit play a role in Achilles tendon health. Your DNA provides instructions for making collagen and other proteins found in tendons.

Certain gene variants can either fortify your tendons or render them more susceptible to injury.

COL1A1: The Collagen Connection

The COL1A1 gene helps produce a type of collagen called type I collagen. This collagen makes up 70-80% of Achilles tendons.

A study found that people with a specific variant of COL1A1 had a lower risk of Achilles tendon ruptures.

This finding suggests the gene’s significant influence on tendon strength. People with a high-risk version may need to be extra careful about preventing Achilles injuries.

MMP3: The Enzyme of Balance

The MMP3 gene encodes an enzyme that regulates collagen turnover by breaking it down. Too much of this enzyme can weaken tendons.

A meta-analysis showed certain MMP3 variants were linked to a lower chance of Achilles tendon ruptures.

This implies this gene affects susceptibility to these injuries. 

Poor Training Habits

How you train also influences your risk of Achilles tendon pain.

Common missteps include:

  • Insufficient Warm-Up: 

Skipping an adequate warm-up prevents tissues from properly preparing for the stress of running. This exponentially increases injury risk.

  • Poor Stretching Routine:

Tight calf muscles place excessive strain on the Achilles tendon, eventually causing inflammation and pain. Stretching too much or too little can cause a sore Achilles.

  • Sudden Changes: 

Spikes in training intensity or mileage can overwhelm tissues, leading to overuse injuries.

  • Overuse: 

High-mileage training and repetitive strain from hill work or speed sessions inflame the tendon over time.

Insufficient Recovery Time

Rest and recovery are when tendon repair and strengthening occur. But many runners fail to balance hard training with adequate rest.

Too little downtime leads to:

  • Increased Inflammation: 

Persistent tendon strain causes swelling and irritation.

  • Muscle Fatigue: 

Tired calf muscles transfer more force to the Achilles.

  • Tissue Damage Accumulation:

Microtears in the tendon escalate without proper healing.

  • Impaired Healing: 

Overtraining inhibits the body’s capacity to regenerate tissues.

  • Altered Biomechanics: 

Compensating for pain changes gait, worsening problems.

Runner's Rescue: 8 Gene-Informed Tips For Preventing Achilles Tendon Pain

Runner in starting blocks on track, focus on feet and red running shoes, representing Achilles tendon pain when running.


Let's dive into some gene-smart tips to keep your Achilles happy and your runs pain-free.

But First: Understand Your Body Well

The first step is getting to know your body on a deeper genetic level.
A genetic test reveals key insights about endurance capacity, recovery time, injury risk, nutrition needs, and more.

This knowledge can help you make more informed decisions to optimize health and performance.

For example, a test may show if you have a genetic predisposition for increased inflammation that impacts tissue repair post-running. This clue would prompt a focus on anti-inflammatory lifestyle tweaks.

But remember, your genes aren't the endgame. They're more like guidelines. It's how you use this information that makes all the difference.

Tip #1 - Strengthen Your Calf Muscles

Your calf muscles and Achilles tendon work together when running, acting as a spring mechanism to propel you forward.

So, the math is simple: Strengthen your calves to support your Achilles.

Your genetic training profile can influence how your body responds to different types of training to strengthen calves.

Now, what’s a genetic training profile? 

It is a unique profile that considers your genetic predispositions and helps tailor fitness approaches to suit your individual needs.

How To Strengthen Calves Smarter?

Here are some genetically tailored calf-strengthening tips:

  • Endurance Runner:

If you're genetically predisposed to endurance, you might benefit from higher rep ranges and more frequent calf workouts. Consider 3-4 sets of 15-20 reps, 3-4 times a week.

  • Power Runner:

On the flip side, if your genes lean towards power, heavier weights and lower reps might help. Try 3-4 sets of 6-8 reps, 2-3 times a week.

  • Mixed Genetic Profile:

For those with a mixed genetic profile, a varied approach could work best. Alternate between high-rep and low-rep days to cover all bases.

  • Slow Recoverer:

    If you are a slow recoverer, you might need more rest days between calf workouts.

    • Post-Training Inflammation:

    For runners battling post-training inflammation, gentle, consistent calf strengthening might be more beneficial than intense, infrequent sessions.

    Remember, these are general guidelines based on genetic tendencies. 

    It's always best to consult with a professional who can interpret your specific genetic data and create a personalized plan. This can ensure that your strength training complements and enhances your run training.

    If your genes indicate a predisposition to post-training inflammation, don't worry. You don't need to be stuck with a life of ice baths and ibuprofen.

    Instead, focus on the following anti-inflammatory nutrition and lifestyle strategies:

    • Eat Anti-Inflammatory Foods:

      Diet-wise, emphasize anti-inflammatory foods like wild salmon, leafy greens, tart cherry juice, and turmeric. These nutrients calm inflammation to help tissues fully repair.

      • Alternate Shower Temperature:

      Alternate cold and hot water during post-run showers. The contrast soothes inflammation to alleviate residual achiness.

      • Optimize Recovery Techniques:

      Spend extra time on gentle stretching and consider using compression gear post-run.

      • Sleep Well:

      Prioritize getting 7-9 hours of shut-eye every night to help your body recover and reduce inflammation naturally.

      • Listen To Your Body:

      Take cues from your body. If soreness persists beyond 48 hours coupled with other issues like tight hamstrings, back off training intensity until fully recovered.

      Tip #3 – Incorporate Cross Training Activities

      Cross-training helps in preventing sore Achilles tendons after running. It gives your body variety, challenging different muscle groups and improving overall strength and stability.

      But what blend of cross-training works best for you?

      The answer lies in your DNA.

      For an endurance-focused runner, yoga can help tight muscles and pilates may strengthen connective tissues.

      Meanwhile, a power athlete genetically may benefit more from HIIT and plyometrics.

      Record these sessions in your GENEFIT app and watch your daily scores reflect the impact of cross-training based on your unique genetic code!

      Tip #4 – Adjust Your Training Load To Avoid Injury

      Think of your Achilles tendon as a rubber band. Stretch it just right, and it becomes more flexible and resilient. Overstretch it, and you risk snapping it.

      That's essentially what training load is all about - finding the balance where you're challenging your body without pushing it to the breaking point.

      It can significantly impact your Achilles tendon. Too much, too soon, and you're courting injury.

      But what's "too much" for one runner might be just right for another - depending on the DNA.

      How To Adjust Your Training Load To Prevent Achilles Tendon Pain?

      Here are some gene-specific tips to adjust your training load without overdoing it:

      • Slow Recoverer:

      If your genetic profile indicates slower recovery, you might need to space out your hard workouts more. Instead of two tough sessions back-to-back, try alternating hard days with easy ones or slot in extra active recovery or rest days.

      • Endurance-Type Runners:

      Such athletes might handle higher volumes but need more recovery from high-intensity work.

      • Power-Type Athletes:

      These individuals might thrive on shorter, more intense sessions.

      • Higher Injury Risk:

      If your genes indicate a high injury risk, gradual progression becomes even more crucial. The 10% rule (increasing your weekly mileage by no more than 10%) might be too aggressive. Consider a 5-7% increase instead.

      • Post-Training Inflammation:

      If you're genetically prone to higher post-training inflammation, consider incorporating more low-impact cross-training to maintain fitness while reducing stress on your Achilles.

      Tip #5 – Follow Personalized Recovery Recommendations

      After an intense bout of exercise, muscles rebuild stronger while tissues repair.

      However, the most effective recovery strategies depend on your genetic profile and training load.

      By giving your body the time and resources it needs to repair and strengthen, you're less likely to develop overuse injuries like Achilles tendinitis.

      Thanks to technology, GENEFIT serves daily recovery recommendations tailored to your genes.

      Proper hydration and strategic fueling enhance performance while lowering injury risk.

      While we know that 7-8 glasses of water a day is a common recommendation, individual hydration needs can vary significantly based on genetic factors, activity level, and environmental conditions.

      Strategic fueling, on the other hand, involves consuming the right nutrients at the right times to support your training and recovery. 

      This means paying attention to your body's signals and understanding how your genetics influence your nutritional needs.

      How To Fuel Your Body Properly?

      Let's look at some specific nutrients that can support recovery from Achilles tendon pain, based on certain genetic predispositions:

      • Antioxidant Powerhouses: 

          If your genes indicate a higher susceptibility to oxidative stress, prioritize foods rich in antioxidants like vitamins C and E, polyphenols, and omega-3 fatty acids. 

          • Collagen Boosters: 

          For those with genetic variations affecting collagen production, focus on nutrients that support connective tissue health, such as vitamin C, proline, and glycine. These will help maintain strong, resilient tendons.

          • Muscle Repair Champions:

          If your genetic profile suggests a need for enhanced muscle repair, emphasize nutrients like protein, vitamin D, and magnesium.

          • Inflammation Fighters: 

          For individuals with genetic predispositions to inflammation, prioritize anti-inflammatory nutrients like omega-3 fatty acids, turmeric, and ginger.
