Man, this is killing me. In the summer, I can easily crank two hours before having to relieve myself. When the weather is cold (less than 60 F, is cold for me), I can barely make it 30 minutes before being in pain.
I can only attribute this to not sweating it off. Problem is, I have to make sure I don't go further than my pit-stop allows. No way to go in the woods since I have to drop my drawers to go.
I hate this, I could still do more, if not for the pit stops.
The other problem is, once I pull those bike shorts down, it is darn near impossible to get them back up, not to mention all the layers of clothes I have on (bike shorts, long underwear, then regular shorts)
I have such an issue with muscle cramps that my trainer told me to drink a lot when riding, be even cutting back on the water doesn't help.
Sometimes I can barely get in the door after 30 minutes without...well you know.
Not ready for depends YET!

But I wish I had a solution.
Am I the only one with this problem?
