The events mentioned so far are mostly running. Personally I am planning to do only a few local halfs (Marlow, Windsor, Wokingham), but really only jogging them. Definately no marathons planned.
I'm thinking about the Fred Whitton in May so cycling will be more of a focus over the winter. I'll keep an eye an eye on audax and cyclosportive sites for local rides. I would up for any longer social rides as well.
