Mr. O,
Congratulations on your new "job!" It's thanks to people like you that this sport is thriving (in its niche-y little way).

I think your article is excellent. The only suggestion I'll offer is that you may want to say something in the Before the Ride section about bike mechanical skills. You say the best approach is to have your bike in sound condition which is great advice, but even with a perfectly maintained bike, stuff happens. So it's good to have a few basic mechanical skills like being able to fix a flat, boot a cut tire, adjust a derailleur, adjust a rubbing brake, etc.
