I really like the idea of not only having badges or recognition for riding performance but also for the locations a rider has completed a ride in.
Perhaps broken down into:
1) Number of cities ridden in
2) Number of countries, states, provinces, territories, and continents ridden in
3) Riding through areas of interest (mountain ranges, deserts, famous climbs, famous highways, etc...)
I love the idea of having ridden in 'x' amount of countries, or cities, or areas of geographical note.
