Each time I do a new marathon it will be added to this map so eventually there'll be 48 different yellow lines showing the exact routes of all my races!
The data for each marathon is taken from my Strava, which comes from my Garmin Fenix 5x watch.
The map is created by Ant from Zero Six Zero, whom I met at Yestival and who makes maps for the hardest core adventurers doing the most epic things imaginable. And also my little jaunts! Wow!
