4:38. I have colleagues who travel to European cities (and further) to run half-marathons and marathons. I think they are missing out - 25 miles of trails and 5 miles of quiet roads, lots of those trails either singletrack between hedges or paths alongside woods. Plenty of wildlife - roe deer and muntjac, rabbits by the buzzard-load, and a couple of hares, one not quite able to hide in the growing wheat, super views from the top of Farleigh Hill, and a complete circumnavigation of Amazingstoke without ever making contact with the town itself, except for a short out and back to home.
I did miss the long prep run, the legs got progressively tighter, sooner than I would have liked, but found a good plodding pace for the last 10km (which is probably the easiest of the route), but its in the book, and will now look at running the Basingstoke Canal from Byleet back to Basingstoke (following the course as best as possible after Greywell).
