For those not in the know this takes place in almost every city in the uk at nine am on Saturday, it for people at all levels of abilities and is a supervised run, it is not a race although there are some that go for good times. You can run/walk it and all you will receive is encouragement. Look it up online and get on down there. My first run was 50 minutes for three miles, can do it in 32 now. People even run their dogs in it. Usually a turnout of between a hundred and 300. It is not at all intimidating and very freindly.
