Hi Nikki
You should do under 2 hours if you are training hard doing intervals, threshold and hilly runs to build up your speed and stamina as well as your weekly distance run. I'm doing the full marathon and hope to go through half way in under 2 hours so 9 minute mileing should do it. I'm looking fo a pb of 3:45 which I did there in 2006 but will be happy if I do under 4. Reading is a good half to get a pb but it was a bit warm this year. I missed out by 4 minutes?
I am doing London as I got a gauranteed place through my company after I had signed up for Edinburgh. I'm off for 18 miles LSR in about an hour.
Since the ballot for London went on-line 2 years ago it is much harder to get a place as more people apply. Unless you run for a charity you have about a 1 in 7 chance of getting a place. It used to be 1 in 4.
