I have run everyday since 01/01/2008 until 27/07/2009 and am now having a forced rest for a week. I pulled my back whilst putting up a tent so I am in too much pain too run.
Having this rest is horrible but necessary. I can't wait to run again and hope I have not done any long term damage to my back. It really hurts and I hate it. When I get back to running I think I will schedule in rest days and even rest weeks as I know they are necessary and it will make me run stronger.
