He started with a blog highlighting bicycling in Copenhagen, now Mikail Colville-Andersen runs a consulting firm Copenhagenize Consulting, an international consultancy based in Copenhagen specialising in bicycle planning, marketing and communications.

Aside from the fact that bicycling is cool and I am inspired to pick up my bike again, after I broke my arm over a year and a half ago, the other interesting observation is that someone can start with a passion: bicycling, adds a blog, and now runs a international consulting firm. Nice way to Crush it!
