I am in my fourth week of running and go running every other day. Sometimes I really want to go for a run but don't because of my rest day...I just wonder, am I asking for trouble if I cut down on rest days at this early stage? General consensus seems to be be that you end up over exerting yourself in someway that's almost guaranteed to do injury and I don't want that. I run and walk still at the moment, covering a distance each day of about 2.5-3 miles..
