Oh Hebe, that stinks when it happens. Happened to me twice recently, the first time a couple of bikers came along and helped me out and I was really grateful because I was a few miles out from my vehicle and I was really struggling with it, the second time I tried it myself and after a bit of a work I got it back on. It's a wee bit harder because I have a chain guard but turning the bike upside down really helps instead of being all hunched over and trying to do this we me upside down. If you put your hand behind the derailur and push it foward, it moves forward a couple of inches and gives you the necessary slack to get the job done. It is a VERY messy process but beats walking back.
