Regional/Local Coordinators are wanted who speak the local language, can help finding places and making contacts with local groups and projects. They help plan the route in detail, test roads and find suitable maps for that region. Local coordinators also keep their ears open about actions along the route.
You don’t need to take the responsibility for a whole (huge country), though and you can work in a group! It’s even alright if you decide that you want to take care of a small part of the route – maybe because you’ve cycled it before or live(d) there.
Please get in touch with email@example.com, if you could imagine to coordinate and participate in a part of the route in your area!
