PP -- my old 310XT systematically overestimated my park loop (with 3 sharp corners), whereas my 920XT underestimates it a touch. If I really want to know paces, I resign myself to clocking the laps manually and using a spreadsheet afterwards. I ought to go round it with a surveyor's wheel one day... for now I've made do with careful plotting on Google Maps, very zoomed-in. It's amazing what GPS watches do really, but when you start worrying about the last 1 or 2% they do have their limits.
DrDave -- welcome back. Amazing performance at Abo with such a short block of training. (Well amazing with any length of training by my standards.) Makes me wonder if we often train for too long for marathons.
SL -- you'll surely smash it!
Wardi -- hope you stay clear of it! I'm still having the odd coughing fit, but don't really feel ill any more. Day off today to get fresh legs back, minimal bits of running tomorrow on my regular train trip to see my old Dad, then county XC champs on Sunday -- but I'm not expecting much there given my poor training over the last couple of weeks.
