Going for a bike trip in the French Alps in a couple of weeks.
I will receive the GPX files of the trip in advance.
I would like to know if there are tunnels in the course, so I can prepare by mounting lights and bringing my normal glasses with me.
If there are no tunnels I would prefer to leave glasses and lights in the hotel as it saves space and weight on the race bike.
Anyone any clue how this can be done?
