Lately I've noticed that I've been getting a lot of hits from people searching "cycling from Vancouver to Calgary". I posted my essay on my own trip here and here, so I won't repeat myself, but I figured I'd let you know that I used this company to tour with. I don't see the same trip being offered right now on the web site but their other tours look pretty cool. Also, you should know that cycling such a distance really REALLY hurts. That's all. Good luck.
