I ran Edinburgh in 2008 (not sure if it was the same event organisers then) and thought it was excellent. Agree with price being fairly steep though, but as I failed to get into London via the Ballot again this year £50 is cheap compared to having to raise around £2000 for a charity place!
I was loooking for an answer to the same question, unfortunately didn't find the answer here. Sir David, while I agree that you obviously get a better analysis from physios etc alot of the people you have just recommended to see actually also advise going to have your gait analyised by the so called unqualified staff members you are talking about when you purchase a pair of trainers. The 2 different shops i have had my gait analysed in previously only allow fully trained members of staff to perform this service and each time i was in there for around 2hrs. (maybe you have been unlucky with the service provided in your local running stores).
Mr Spoons: Well done on your PB. With those times I imagine that you'll be relaxing at the end of the 26.2 with a nice cold beer (and the free hog roast)! I'll still probably have around an hour of running to go!!!
Ellen: I had the same issue last year training for Edinburgh, my only marathon to date. The pain started after my 1st 16 mile run and never really went away.
I was probably a bit stupid in not getting it seen to and ended not being able to train for the last 5 weeks before the race. In truth, as I had lots of sponsorship money riding on it, I was worried I would be told not to run. On the day I managed to run, inside my target pace, for 18 miles before my knee gave up and i ended up limping round the last 8. I was pleased to finish it all things considered, but in hindsight I should have seen a physio.
I ran the New Forest half since then (which I loved) without any problems but have not run that distance since, so it will be interesting to see what happens when I start getting the longer runs in this time round. I will definately get it seen to this time if it reoccurs. The good thing as you say though is we've got plenty of time on our side. I would suggest resting it up and icing for a bit to see how it goes, just don't make the same mistake I did last year if it does persist. Good luck and heres hoping for an injury free training schedule for all!
