perfect Dachs....a "legitimate" 10k within a half should definitely have at least a min to come off in a stand alone 10k i'd have thought. Would like to think i'd be mid 35 10k at the worst right now, so that'd stand up!
Phil - interesting idea...maybe. Would take a bit of logistics to work out. Or maybe it wouldn't...just turn up a couple of mins in, and have fun monstering past people. Although to produce HMP/MP on that course would probably be a higher intensity. But will weight it up.
Simon, i remember that first rep after! Never great fun. However, so much better than just unleashing without stopping, that I tried once. Not a good plan
My splits were 17:19 / 16:54 / 17:32 / 16:59 with 4:19 for the remaining 1.1 km. The issue I suggest was the placing of the 20km mat, cos there's no way I was crawling in the last kilometre at 6:18 minute miles, however tired I was.
