What if your kids can't keep up?

Early on, when my kids were young, I had a two-seat sport stroller that I could push them in while I went running. I could also tow them in it behind my bike. It was great, until my daughter realized she could whale the tar out of her older brother and there was no way for him to escape. And that was the end of that. Screams of terror ruin the Zen of exercise.
