Finding enough water to drink was a major problem. When you are cycling on quiet roads there aren't any service stations and when you do find one there is a fair chance that it won't have a tap or toilet. There aren't any taps or drinking fountains in the parks. It's normally not hot enough to bother about things like this. You have to stop and ask a householder to give you some water or find a public toilet.
Soft drinks are very expensive to buy and the cheapest drink to buy in a supermarket is milk.
You can buy a litre of milk for half the price of a 330ml bottle of soft drink. When I reached Ringsted, I had travelled 97 km on bike and had spent over an hour on the ferry. The next day I had 35 km to cycle to reach Roskilde which was to be my destination for nearly three weeks. During that time I made a number of short trips away. This is another city with numerous old houses and buildings dating back to the early 1600s.
