Marathon and Ultra Training: What Your Body Is Telling You

From Pavement Miles to Mountain Trails

Training for a marathon, trail race, or ultra run pushes both physical and mental limits. Whether you are logging miles on pavement or navigating technical singletrack, the repetitive nature of running places significant stress on the body.

Many runners notice a similar pattern. Early in training, everything feels strong. But as mileage builds, small aches begin to appear. Left unaddressed, those minor issues can develop into overuse injuries that interrupt training and delay race goals.

At Vail-Summit Orthopaedics & Neurosurgery (VSON), specialists including Dr. John Paul Elton, Dr. Richard Cunningham, Dr. Max Seiter, and Dr. Terrell Joseph frequently evaluate runners dealing with overuse injuries related to endurance training.

Quick Takeaways

• Marathon and ultra training increase risk of overuse injuries due to repetitive stress.

• Pavement running and trail running place different demands on the body.

• Foot and ankle injuries are among the most common in runners.

• Knee and hip pain often develop with increased mileage or poor mechanics.

• Early evaluation can prevent minor issues from becoming long term injuries.

Pavement vs Trail Running: Why It Matters

Not all running surfaces are the same, and each comes with its own set of stresses.

Pavement running

Road running offers consistency, but the repetitive impact on hard surfaces can increase strain on joints, tendons, and bones. The lack of variation means the same tissues are loaded in the same way, mile after mile.

Trail running

Trail running introduces uneven terrain, elevation changes, and variable footing. While this can reduce repetitive impact, it increases demands on stabilizing muscles, particularly in the foot, ankle, and hips.

Many ultra runners train across both environments, which can compound stress if training volume increases too quickly.

Common Overuse Injuries in Runners

Overuse injuries develop gradually. They are typically the result of repetitive loading without enough recovery time.

Common factors include:

• Rapid increases in mileage

• Inadequate recovery

• Muscle imbalances

• Poor running mechanics

• Improper footwear

Recognizing early warning signs is key to staying consistent with training.

Foot and Ankle Injuries

Dr. John Paul Elton is our foot and ankle specialist at VSON.

The foot and ankle absorb and transfer force with every stride. In long distance runners, these structures are under constant demand.

Common foot and ankle injuries include

Plantar fasciitis

Pain along the bottom of the heel or arch, often worse in the morning or after long runs.

Achilles tendonitis

Tightness and pain in the back of the ankle, especially during uphill running or speed work.

Stress fractures

Small cracks in bones such as the metatarsals caused by repetitive impact.

Ankle instability and sprains

More common in trail runners due to uneven terrain.

Dr. Elton often emphasizes that early symptoms should not be ignored. Small issues in the foot and ankle can quickly alter running mechanics and lead to injuries higher up the chain.

Knee Injuries

Dr. Richard Cunningham, Dr. Max Seiter, and Dr. Terrell Joseph are the VSON knee specialists.

The knee is one of the most common sites of pain in runners, especially as mileage increases.

Frequent knee conditions include

Runner’s knee (patellofemoral pain syndrome)

Pain around or behind the kneecap, often worse with downhill running or prolonged sitting.

IT band syndrome

Pain along the outside of the knee caused by irritation of the iliotibial band.

Patellar tendonitis

Pain just below the kneecap, especially with speed work or hill training.

Dr. Cunningham notes that many knee injuries are related to load management. “When training volume increases faster than the body can adapt, the knee often becomes the first place symptoms appear,” says Dr. Cunningham.

Dr. Joseph adds that biomechanics play a major role. "Strength and alignment throughout the lower extremity directly influence how stress is distributed through the knee," states Dr. Joseph.

Hip Injuries

Dr. Max Seiter is VSON's hip specialist.

The hips are critical for stability and power in running. Weakness or fatigue in the hip muscles can lead to compensations that affect the entire kinetic chain.

Common hip related injuries include

Hip bursitis

Pain on the outside of the hip, often aggravated by longer runs.

Hip flexor strain

Discomfort in the front of the hip, especially with speed or uphill efforts.

Gluteal tendinopathy

Pain and weakness in the lateral hip that can affect stride mechanics.

Dr. Seiter explains that hip strength is often overlooked. "When the hips are not functioning optimally, runners may experience symptoms in the knee or foot even if the root cause starts higher up," notes Dr. Seiter.

When to See a Specialist

You should consider evaluation if you experience:

• Pain that persists beyond a few days of rest

• Symptoms that worsen with continued running

• Swelling, sharp pain, or changes in gait

• Pain that begins to affect daily activity

Many runners begin searching for a foot and ankle doctor near me or a knee doctor near me when training becomes limited by pain. Early evaluation can help identify the cause and prevent further progression.

Treatment and Prevention

Most overuse injuries can be managed without surgery when addressed early.

Common approaches include:

• Activity modification and structured return to running

• Physical therapy focused on strength and mechanics

• Mobility work and flexibility training

• Footwear and running surface adjustments

• Gradual progression in training volume

For more advanced cases, imaging and targeted treatments may be necessary to fully resolve symptoms.

The Bottom Line

Training for marathons and ultra races places unique demands on the body. Whether running on pavement or trails, repetitive stress can lead to overuse injuries in the foot, ankle, knee, and hip.

At Vail-Summit Orthopaedics & Neurosurgery, specialists including Dr. John Paul Elton, Dr. Richard Cunningham, Dr. Max Seiter, and Dr. Terrell Joseph help runners understand the source of their pain and develop a plan to return to training safely.
