Running

Also, marathon training has gone out the window. It's on March 17. Do you think. Can just jump into this training plan at the appropriate point?

I'd strongly advise against it, but then I'd advise anyone who hasn't been running for a few years against running a marathon, I jumped into one too quickly (6 months after my first half) and despite a pretty good adherence to a beginners training schedule really struggled on the day and it put me off running for a long time.

To my mind when you reach the half way point in a marathon you're about 1/3 of the way in terms of physical exertion and pain.
