I used to have a bumper sticker on my car that said "who fartlek'd?" Honoring my Swedish roots and my running.

I never considered riding random hills as fartleks, but that's a really good way to look at them. I don't generally do structured hill workouts, but we have several routes around here with good hills. I like to incorporate them into rides when I want a good, hard workout.
