Well I've been looking at the training I will need to do for the running. I know I can do a half marathon straight-off now if I wanted to, however I would not like to run any further really without any hydration etc. provided en-route.
I'm thinking that I should keep doing 10k runs on a daily basis, weather permitting, with rain days spent on the elliptical trainer for anything up to two hours. In the build-up to the first marathon I want to be building-up distance runs on the weekends before: 12 - 15 - 18 - 21 miles so the big day will not be too much of a shock to the system.
