Well that was rather good!
I reckon there were over 400 people there... from all over the place too. Plenty of tourists to bolster the numbers and lots of cameras so no doubt we shall we in the local papers.
Long introduction from the RD, Stratford's mayor and the health & safety official. Eventually got underway and I quickly realised I had started way too far back and was struggling to get past people. Thankfully the course opens up after a few hundred metres and I was off! Must have overtaken well over 50 people. First km was 5:48, final km 4:31... I had enough in the tank for a sprint race at the end with another guy (roughly the same build as me) and I won! Not keen on the grassy bits which will no doubt get very chewed up if there's a long period of rain before a run.
Lime Green Laura says I did it in 26:06. Will post official time when I get it.
