Q: I got into the Boston Marathon. I’ll be using the intermediate marathon plan – should I keep the Wednesday workouts, or should I make any other changes?
A: Congrats on your entry into Boston. Despite everything you hear about Heartbreak Hill and how brutal it is, Boston is actually a very fast course – in fact, the world’s fastest time was run there a few years ago, although it doesn’t count as a world record because of the course’s net downhill profile.
Running intervals during the week is a tradition of most marathon programs. The workouts are relatively short, so they can be squeezed into a workday schedule, and they are far enough from the long weekend run to allow enough time for healing and recovery. As explained in Smart Marathon Training, speedwork is a cornerstone of race preparation, and your preparation for the Boston Marathon doesn’t require any change from this.
