Great article, very funny, and very much linked to our discussions about being smoked by kids :

"To take his swim to the next level, professional triathlete Jesse Thomas subjected himself to the worst kind of torture—working out with high school kids. "

"But the social exile is nothing compared to the athletic ego deflation. There’s a nice 14-year-old girl who swims in my lane—and smokes me 95 percent of the time. I have secretly started calling her Nemesis. At this point I don’t know if I’d rather podium at a world championship or win one stinking workout against that girl.
Recently Nemesis and I did a 1K time trial. I had stayed with her on the previous few workouts, so I assumed we would swim similar times. She was in the heat before me and went out like a rocket. I told my wife, “She’s going out way too hard. She’s going to die so bad!” Well, she held it, finishing in 11:08. This surely meant I would demolish my goal of 11:40. I jumped onto the block full of enthusiasm, had a clean dive and went out strong. I finished in 11:50."
