Oops, my mistake. Forgot the "add on 2 seconds" rule, so 16:30 officially. I had tried to subvert this rule by actually waiting 5 seconds after I crossed the line before stopping my watch, but the rule is universal and cannot be countered. I could cross the line, walk home and have a cup of coffee and eat an entire watermelon, and then stop my watch, and my official time would still be 2 seconds longer.
Assumed course always measures 5.1x km for me, so plenty of modification needed.
Well done SS.
Ran Bracknell parkrun this morning. It seems it is entirely uphill and designed by Escher himself. Apart from the bit that looks like an uphill, but is in-fact downhill. A whole new course to learn how to run. Nice springing woodchip path section through the woods with the pines smelling nice. Ran there and back too, so just shy of 10mi in the bank. Plan said run steady (~HM pace) so was hoping for somewhere between 4:15 and 4:30/km, and after the week I'd had it came out at 4:23/km. Happy.
