Marathon Running – Making sure your feet are ready

Running long distances, such as marathons, asks a lot of your body. If we believe the story from ancient Greece, the individual who ran the extended distance to report victory of the Battle of Marathon died shortly after arrival due to exhaustion. The mondern marathon may only be a tenth the distance of that feat, it is still a challenge for your body, especially your feet. The pressure of a single foot striking the ground with the full force of your body can have damaging effects over 26.2 miles . 


Fractures require immobilization while they heal and are the most limiting of any foot injury. Good nutrition and a balanced diet, including vitamins C & D, are crucial for good bone health. By training properly and slowly increasing the distance you run over weeks and months, you give your body the chance to build the bones up stronger allowing them to stand up against the new challenges. Cramping and tendonitis can also be avoided by building up to long runs and not doing too much, too quickly. If you have given yourself able time adapt to the new distance, the problem may arise from the structure of your foot. This just means your foot needs extra support in the right places. Austin Foot and Ankle Specialists have shoe recommendations for your foot structure or you may find that you benefit greatly from a simple over the counter arch support. Some feet may require customized orthosis to provide this support. 

Calluses and blisters occur when there is too much friction between your foot and the sock and shoe. Poor fitting shoes can result in these problems as well as blackened toenails. All three of these are a result of a repeated trauma to the area of the foot. To avoid them, wear good socks with proper padding and make sure your shoe is a good fit.

Even if you are a regular runner make sure you take every step to prepare your feet for a marathon. While prevention can be the best cure sometimes, don’t hesitate to contact your Austin podiatrist if foot or ankle pain is affecting your marathon training.

Avoiding Blisters - Keeping your feet in running condition

Blisters may be the most common malady for sports in general. For anyone who runs long distances or marathons, you may have come to accept some skin chaffing, blisters on your feet, or blackened toenails as a price of completing this feat. You shouldn’t! Just like you can avoid chaffing with proper clothing, you can also take steps to avoid blisters. Before we talk about the best way to avoid blisters cramping your run, let’s talk about why blisters form.

When we run, or walk, the forces that propel us forward also create forces where our feet meet the sock, shoe, and road. The back and forth or side to side forces create a friction between your foot and the surfaces it contacts. Your increased body heat, and moisture from sweat can greatly multiply these frictional forces. The talcum powder or Vaseline that you may have been told can help actually does so for only a short time. After about an hour, these products actually increase these forces as well. Your skin is made up of five layers. Over the miles, these frictional forces cause a cleavage, or tear in which the top three layers pull away from the bottom two. This area then quickly fills the clear fluid that is the trademark of blisters.

The blackened toenails we mentioned earlier are often a result of poor fitting shoes. If the fit is loose enough for your toes to slam against the front of your shoe, there is also a good chance there is enough slide to form friction blisters. This isn’t likely the cause for most runners. Instead, you should look at your socks and insoles in order to resolve this potential problem. Because moisture amplifies the friction, consider ditching cotton based socks and look for something that will better wick away moisture and keep your feet dry. The next thing you should look at is your insert. Is it worn in any area? A good insert can decrease frictional forces by 25%! All these things can help prevent blisters from occurring. If blisters do form, despite all these precautions, you shouldn’t pop them as this will increase pain and leave you open to infection. Instead, visit your Austin podiatrist who can show you how to properly treat and protect this area.

Keep those feet running and pain free Austin!
