There were so many things wrong with this run: the planned route had non-existent tracks and sandy tracks, the app didn't re-route when off route, when app lost GPS, it would say the wrong directions, water bladder stopped working mid-run, (bad) backpack chafed my shoulders, backup Garmin watch died, got very lost and stopped too many times to check map, before giving up and just winging it. On the upside, I sill managed to bike about 8km after to get home!
