I got a ballot place this year and a second chance ballot place last year. Last year was my first year of running it and having only ever run races in France, I found this race very lonely. I can usually find someone of a similar pace to run with, chat to from time to time, in races in Normandy, but I was very much on my own in London last year. I am giving it another go this year and if it is the same again, I shall not do it again.
I don't think it is expensive and the route is good, although some areas of the park get very congested. When people stop and walk without any warning or without stepping to one side, it gets quite annoying. Other than that the organisation was excellent.
One tip if you are going with friends... don't expect to get hold of anyone by phone afterwards as there was absolutely no signal to be had. Organise a meeting place before you set off, so that you can find each other.
It could almost have been me who wrote this... It is how I started and the more people I told, the more I couldn't stop. Even when someone said to me, I wouldn't have the guts to be seen by people I know, running around town, like you do... as I was 18st 6Ibs, I kept going. After 8 months and -6 stone, I was still running 3-4 times a week and still am, nearly 2 years later. I often compete in races, just for the fun, as I am not fast enough to ever win anything.
