Length isn't everything....

 ...as the actress said to the bishop*.

Over the Easter weekend, I went out with my walking group on Easter Sunday and Easter Monday.

The walk on Easter Sunday was 20 km long but flat - in the countryside near the Dutch border. Lakes, fields, a heath and forest. Easy peasy.

The walk on Easter Monday was supposed to be 12 km but hilly. I was more tired after the first 10 minutes (with 124 steps to get out of the valley and on the hillside) than I had been at the end of the previous day's walk. Phew. 

We had some newcomers to the group who thought that 12 km was going to be easier than 20 km, but as I soon told them, you can't go by length. The main criterion as to how knackering a walk is going to be is how hilly the countryside is. 

*In the UK, you can make a double entendre simply by adding the words "as the actress said to the bishop" at the end of any sentence that can be read with a salacious [wollüstig] meaning.
