My marathon training is their warm-up

I've run two marathons and three half marathons. But I'd probably be no match for CrossFit, a strength and conditioning regimen that some call cult-like.
“How many reps would Jesus do?” jokes CrossFit member Trailgirl.
In its March 23 story about CrossFit, the New York Times says a workout of the day, or W.O.D., might include, “50 kettlebell swings, 3 800-yard dashes in rapid succession and 10 pull-ups. Repeat. No breaks.”
Let me just say this: CrossFit can keep its kettlebell swings. I'm proud of my daily 5-mile runs.
