It’s late-summer and suddenly some friends tell you they’re going to run a fall marathon—and you should join them. What?! Is there time to get in decent enough shape to finish it? Yes, of course, assuming you’ve been active and running a bit since the spring. We’d normally suggest a 12- to 14-week plan for optimal marathon training, but if you don’t have that much time you can still improve your situation in the next two months. Here’s an eight-week plan aimed at getting you to the finish line with more aerobic fitness than you have now. You might not set a new PR, but you’ll still savor the moment you cross the finish line.
