Route Geographics
The TD Leaderboard (Google Maps) is perhaps the best online map view of geography the GDMBR traverses. Note: When zoomed-in, the Leaderboard's GDMBR overlay (displayed in red) only loosely represents route detail as it contains only a fraction of the actual GPS waypoints (detail) in the interest of page-load speed.
Map Addenda: Updates and corrections to route maps are issued annually by ACA. It is essential to obtain these addenda as they contain changes on mileage, routing, services, etc. Read more about addenda here.
