I am currently on a marathon training schedule to be completed in late April. There is a lot of work to get yourself ready for such an event (as I am discovering and I have only been working on it for a month!). When it is over, how do you keep up that fitness? An hour or two run a couple times a week? Then upping it when a race is on the horizon? I am still very new to long distances, but I dont want to "waste" my training by only running one race and having to start from scratch for the next one.
