Shalane Flanagan new training after traumatized from London

@ShalaneFlanagan is set to run her first Boston Marathon, a race that's been on her bucket list for 17 years. The marathon follows what she calls a traumatizing last marathon at the Olympics in London. Over her last 4 miles in London she "rigged" and faded to tenth place. Although she was proud of how she ran, she still left disappointed. Flanagan has taken a more conservative approach to training this time around (interpret that lightly...she's still over 115 miles a week) as she looks to win the first major marathon of her career.
