One of the challenges is to ride 50 50 miles dayrides. In practice for me this is just to think about taking photos at the start of the ride and at the end. Thinking about it, I am used to just riding a big ride around the block, but it has become more. Usually I have a goal when I do so. Simple goals like taking photos of war cemeteries, go to work, visit a bike rally. But now it is also for the infamous Challenge 5E. (and getting an expert in taking photos of cockpits.....)
