“Loss of blood supply due to atherosclerosis can lead to life-threatening gangrene. Thank goodness for claudication. I see pain as my teacher and while running as my coach. Pain is my body’s way of saying, “Watch your pace, Kevin. Soften those feet and spread those toes, Kevin. What the hell are you doing, Kevin?”
Here’s a recent example of an intense foot pain that provided me with some running instruction.
As I went through the finish chute of the 2022 NC70.3 Half Ironman race, the ball of my right foot was on fire. I wondered what the hell was going on.
I finished in spite of the pain, which earned me a spot in the 2023 World Half Ironman Championships in Finland. There were only 17 of those coveted slots for a field of 3,000 athletes and I got one by finishing first in my age-group.” – From: How to Fight The Crippling Pain of Peripheral Arterial Disease

Luck of the devil, some say.
I finished in spite of the pain, I reply.
The next morning I found several small corns on the ball of my right foot. One near my big toe and two near the little one.
“Corns and calluses are thick, hardened layers of skin that develop when the skin tries to protect itself against friction or pressure. They often form on feet and toes or hands and fingers. For most people, simply removing the source of the friction or pressure makes corns and calluses disappear.“
― Mayo Clinic
The key phrase: “… simply removing the source of the friction or pressure …”
Those corns are nearly gone, as I’ve been “Sciencing the shit out of the problem,” to quote Mark Watney, in The Martian movie. I’ve been using the methods described in my book, below. Took a while. Anything worth doing usually does take a while.
It’s all laid out in my latest book, which was fun to write, I must admit:
Never give up, just study, analyze and fix as best you can.
And don’t forget, “A life without risk is no life at all.”
