Maybe it is how much you are drinking before? If I drink a lot before a ride I will need to potty early on. I can go that distance without needing a break if I am just drinking on the bike (usually 20-40 oz). Ihave been known to be guilty of drinking too little. I think I would take needed to potty over dehydration or heat illness any day!

**Hehe I guess drinking before makes me have to "break the seal". I had the other type of drinking on my mind when I saw the title.
