>>1475589>1. According to google maps I would have to go about 550km. Are 5 days a good estimate?You can do 110km a day, but take a week, a day off every couple hundred km is nice.
>2. I only have backpacking gear and a bike. I assume the only things I would still need to buy are proper bike bags and maybe a repair kit. I own a tent and the ususal camping equipment.yep
>3. How am I supposed to buy stuff without leaving my bike alone? I cant just buy a lock for every single bag of equipment.Not much of a problem in the German countryside afaikt, just lock up your bike oudside the store
>4. How much training would I need, assuming that I am in relatively good shape but a bit skinny? I dont ride my bicycle more often than once a week usually atm.Not much as long as you keep to the flatter parts of Germany, buy some cycling padded underpants, or your ass will hurt
>5. How does one find a good camping spot while biking? When walking through the forest I usually just go away from the path to find a lonely place where nobody is going to see me, but I will probably just cycle on proper ways without good opportunities. Do I just drive away from my road into less crowded areas in the evening?Wild camping is frustratingly illegal in Germany, I suggest you use the official camping grounds which are plenty and have pleasant surprises like Berlin student girls playing nudist volleyball with you. Other than that, MV has a a couple legal designated wild camping areas, those are also good, other than that, ask the local farmer for permission if you wanna hunker down on his land.
t. biked twice from Berlin to the Baltic sea, then along the coast down to Hamburg.
