I am a regular runner who runs about 15-20 kilometers a week, however, one of my friends suggested that continuous running may have some side effects during the later part of life (i.e.: after 50). How much truth is there to this? If true, what are the chronic effects?
I'm a female runner who runs 3-4 miles 2x a week, and I develop a hole in the honeycomb mesh of my running shoes right above my right big toe after about a month. Are there any running shoes that would prevent this?
