She was profiled in Runner’s World after the Presidential Election wearing...gasp....running clothes.
She’s a runner, as in exercise. Has been all her life.
Yes, sports have been such a big part of her life that several of her children have been named over the sport which was in season when they were born.
Which is precisely what makes me think the running outfit might have been an insiders' joke--but it is not proof.
Cheers!
PS Apparently Dubya gave the Secret Service *fits* trying to keep up with him in terms of exercise: sit-ups, I've read, and trashing the editors of Mountain Bike Review when they tried to compete with him (22 mph on the road on a full-out mountain bike; and burning up 1600 calories in 2 hours on a bike. My college-age son, who runs sub-five-minute miles, can sustain 22 mph on a mountain bike on the road, but not too many others can).
