Hi Matthew
Thanks for the message, the course as Emmy says is 90% flat and is abd out and back course through Richmond Park and then along the Thames Path to Putney Bridge and back to the school where you get a nice hot meal and your lovely medal. Ithink if its a nice sunny day, not to hot you wont have congestion issues as you would on a big road marathon course. In terms of PB potential its not pancake flat on just the penultimate hill but apart from that its flat/downhill so I think you could well achieve a PB. Aside from that its a lovely, scenic course and I think youd really enjoy it. Have a look at the You Tube feeds on the above link and tell me you're not inspired to run it PB or not PB ! Thanks Emmy for your feedback too it will be great to see you again and its going to be bigger and even better than last year.Hope your training goes well Matt & Emmy.
