There's an old saying that the marathon consists of two halves: the first 20 miles and the last 6.2. In this edition of LET'S TALK TACTICS, I'm going to argue that that's exactly how you should run your next marathon. Bearing in mind that this is a series dedicated to learning from elite competitors, I want to take a look at two breakthrough races illustrating this tactic: First, Galen Rupp became the first American male to win the Chicago marathon since 2002 (and first American- born male since 1982), coming through in a time of 2:09:20 -- off of a 1:06:10 first half.

Just a few weeks later, Shalane Flanagan followed...
