>> first off, why would somebody who has accomplished so much say why don't i just try 26.2? >> it's kind of like one day i'll run a marathon. you have this fear of retirement and great way to put competitiveness back in my life and i wasn't expecting it to be four months after giving birth to my second child. >> what's the headline? she just had a baby, all right? all the women out there will kind of be angry at you for looking like you do. they'll be like wow, we admire you. this is your first child, right? >> yes. >> you have two little boys at home. how did you get in shape for a marathon after having a baby? >> i have an awesome coach, timex hooked me up with a coach. this watch is like a trainer on my wrist. >> you've run 19 miles has been your high so far. if you do 19, you know you can do 26. you're going to wear the watch. you're not going to wear a headset. so you're going to start in the very back.
