Compared to running or biking? A 5k swim is roughly equivalent to a half-marathon run. I can't imagine anyone would run 13 miles without even a sip of water.

ok, I've conducted some google research and there has been some studies conducted on this. The results seem to vary quite a bit but I surmise sweat loss during swimming is about 500ml per hour, vs running of about 1.5 L per hour with a lot of variance with weight, intensity, heat, etc..
The amount of sweat loss is individualistic. You can weigh yourself before and after exercise and determine your own sweat rates. Wonder if anyone actually does this?
...I typically drink about 30 oz of water over the course of a one-hour swim workout. With this habit I am afraid to swim over an hour without water, but perhaps this is more of pyschological need than a physical need?
