So just for the record: I got 1:41:46 (a PB by quite some way, and pleasingly beats Ross in Peterborogh). I also beat James this time (1:44:22) but he was deliberately (and slightly failing) trying to run at "marathon" pace.
As I said on heiaheia:
Went well, new PB, just a teensy bit disappointed not to be a minute faster.60th in my category, viz V45 men. Overall, 430 of 1971 (http://www.chiptiming.co.uk/pdf/NorwichHalfMarathon2010.pdf).
