Now if you are working hard enough on the bike- No need to pee.

Long rides in summer and I am taking at least 1 litre of liquid an hour. Difference in a long ride is I know I will have to put effort in and do. Those short 40 to 50 mile rides are at a lower pace and not quite so much liquid taken on board. Problem rides are the short 20 milers- but they also involve a cafe stop with at least one cup of coffee so before leaving the cafe- its time to use the loo.
