Zipping up the hills

I have a cycling partner (we'll call him "Jason"), who has this incredibly annoying habit of flying up rises and hills like they weren't even there. He doesn't even slow down. As I said, annoying.

I was leading one of the Portland Velo 17's groups this past Saturday... and found myself doing just that. Seated. I'd keep on going, look back, and most of the riders would have fallen back. My. Don't know whose legs these are, but I'll have to keep them!
