This is an interesting debate. I am attempting to train consistently this year and improve my stamina and speed but rest days are an important part of that. From the limited experience that I've had, I not only run faster but also enjoy myself more when I include rest days. Last year I had a few weeks where I trained and did three races a week (road, cross country and fell) and I was knackered and suffered in other areas of my life with poor concentration and lack of creativity. Like HHH and some of the others say...it is about striking the balance between the rest of my life and running. I like to cycle too so I often do that on a non-running day.

However, I am not looking for an international vest just to be the best I can be and enjoy it. Good luck TurboTom, you've obviously got determination, just be careful not to burn out or injure yourself and don't think it is the end of the world if you miss one session.
