Does it only have to be 3 times a week?

I think it's more 'run at least 3 times a week' rather than only Paul, so go ahead and run to your heart's content!

Cheers Cags and always enjoy running and normally run 4 or 5 days a week during my lunch hour :-D

Have always been told not to run on consecutive days as it does not give your muscles enough time to repair and ultimately performance is affected. So I guess 3 times a week would concur with this.

I always try to get 3 runs in a week. Although sometimes I want to run more. If I add a 4th or 5th run then I make sure they are light (maybe shorter or slower pace). I definitely need 2 rest days in my week.
