I live in the flat too, i get excited by the view of the smallest rock already. When i started touring i thought i could not ride anywhere near mountains because i felt rolling hills were killing me already. But then i got kinda bored riding along a river and tried cycling in some mellower mountains and liked it much better. Especially if there’s hardly any traffic. Ever since i try to do my tours where there’s mountains.

If you take your time, low gearing, you’ll eventually be up there. Have a snack, drink a coke. Enjoy the view and fresh air

edit: I also don’t train cycling at home or anything, don’t think riding to the pub and supermarket counts. But of course it wouldn’t hurt either. Now i am in good shape though, since i’ve been a good two weeks into the tour.
