I've heard people doing 40 at 40, 50 at 50, so i came about well why not 20 at 20? I turn 20 in November this year so i'm going about planning a course. I've had a look at the wainwrights around keswick which seems a reasonable area to fix a circuit, just posting on here if anyones got any suggestions of a good group of hills or if anyone else has heard of a "20 at 20"?
