Many people see some runners in their neighborhood who puff and groan as they run around the streets. They look under stress, unhappy and completely wrapped up in their own thoughts.
My experience is that this sort of runner is a very small minority who are perhaps over-exerting themselves. Some people might think they are being forced to do it!
I don’t think they would continue if they weren’t getting some benefit from their effort.
I hope that some of them will read my book so they can find out how to reduce the pain and increase their gains.
I will help you by explaining the choices available to you and suggesting ways to fit running into your daily life with minimum impact and maximum effect.
