The important thing for someone over 50 is to make sure that what you urinate is at least half of what you drink - my problems started because I was drinking more than I was eliminating, and the urinary retention that followed has caused me a number of problems...

I regret not being mindful of what was happening, because I would just think it was part of being middle-aged, not realizing that I wasn't retaining more than I was drinking...

This has been my experience. I no longer drink straight water after a hot century several years ago where I flushed all the electrolytes out of my system. I find that using Nuun has made a big change in my ability to properly hydrate.

The riders who start off a ride with normal levels of pre-hydration usually do not need to urinate during the ride, or at least less often. Physicians say its about normal kidney function during intense aerobic exercise.

Prepping for longer rides, like doubles and steep/difficult centuries, I add a few more glasses of water each day the week before, and, since no way I'm giving up coffee, it's a stop every 15/20 mins for the first few hours, but I stick with the hydration plan and finish strong.

The stops don't take long.

Ahem... when ya gotta go

For shorter rides, it's become a matter of experience, although still occasionally get just a smidge too dry. Margin for error here in much bigger than summer in Chico, where a full bottle every 20 mins may be necessary as the merc wanders north of 100F.

Here, over 75 F is "hot."

I occasionally use a belly boat (inner tube with a seat) when fishing small lakes and ponds. When I first started, I could paddle close to shore stand. drop my waders and pee beyond the inner tube. After a few years that changed to I could pee beyond my waders. Now I just tell everyone that my waders leaked!
