Do A Hard Run 3 Weeks Before Your Marathon

I know that the Hansons do this, too, about three weeks out from a marathon. A lot of people think if you can do 16 to 20 miles at marathon goal pace, without a taper, you should be able to then take a two-week taper and then do the whole marathon at that pace. -Josh Rohatinsky speaking about a 20 mile time trial he did at 5 min per mile in his NY Marathon preparation runnersworld.com Josh ran 2:15:22 in his marathon debut, placing him 9th in the U.S. Olympic Trials.
