Thanks for that Ian, you have confirmed what I was thinking despite reading all of the 'How to run an Ultra' web sites. I guess as from October next its a case of getting over to wales as often as I can. I seem to remeber conversing with you b4 about the PBR, unfortunately I failed last year with sore knees on leg 2 (Hebog) which I find for some reason the most difficult of all legs to keep to time in despite all the walking up hill. From hebog onwards I lost an hour negotiating Y Gwym and trum y ddysgl.
regards
Simon
