BG Club Members 173 and 174, Peter Haynes and Dave Kingham, did the Round while they were students at Cambridge (as I was at that time). Peter's home was in Guildford, and Dave's somewhere in Hertfordshire, so slightly more hilly than Cambridge; but they did a lot of orienteering (often in hilly areas), and the occasional Mountain Marathon. I remember being with them during the planning stage, looking at maps, when we measured the route several times and couldn't get it to be more than 63 miles; at that time it was said to be 72 miles. We now know that 63 is much nearer the truth.

Incidentally, Bob, the "n" is missing from "Haynes" on the BG Club membership list.
