As I was riding along today, I thought wouldn't it be good if there was a thread full of handy tips for planning your ride.

The reason my mind was wandering was because I was on a 105 mile ride and I had reached 45 miles so pretty close to the furthest point so it was impossible to shorten the ride. At this distant location, I suddenly thought, "Oh no. I need a crap." I was riding solo and I had no lock for my bike; I was in a whole lot of trouble. To keep my mind off my bum, I concentrated on interesting and distracting thoughts, avoided moving about too much on the saddle and rode like hell to get home.

The simple fact is, even if I was with other people, how would I have raised the subject. Hold my bike, I'm going for a dump in this field. No way.

The only answer was to evacuate my bowels fully before setting out on a long ride. My tip. What tips can you offer?
