Hopefully if travel is back to normal next year I will be cycling from my hometown in Ireland to Cape Town. When touring I like to carry as little as possible by carrying only as much as I need. So far this has meant only carrying one map of Ireland. To keep the weight down i'm thinking of buying a Garmin Edge 530 but i'm not really into tech so i'm not really sure what to expect from it. My question is can anyone tell me if it's possible to travel the whole way to Cape Town without maps and only using one of these GPS bike computers? I'm not fussy on exact routes. I plan to just jump on the bike next May and start cycling across Europe, fly from Athens to Cairo and cycle down East Africa to Cape Town without any real plan and taking a direct route.
