At 10 o'clock in the morning, hundreds of people lined up to grab a cold one.

"The funny thing is I don't even like beer, I don't drink beer on a regular basis, but after a race it's what I want," said Lisa Tessarowitz , who just ran the marathon.

It's what many Cowtown racers wanted, what some even dreamed of 26 miles to the finish line.

"You see the shirts that say "will run for beer," there's a reason for that," said Brian Butner, a beer distributor.

A study by Spanish researchers at the University of Granada suggests beer may do the body good, at least after a workout. That's something these runners already know.

"Tastes great, replenishes your body, does all the right things you know," Tessarowitz said.

The researchers claim the sugars, salts and bubbles in brew can help athletes absorb fluids faster than drinking water. Their study, which spanned several months, asked 25 college students to run on treadmills in 104-degree temperatures. Those who drank beer were slightly more hydrated than those who had H2O.

At Cowtown, the beer was free and free flowing. A crowd of racers ran thru 60 kegs. Of course the "beer after workout" philosophy has been met with skepticism because alcohol can increase the amount of liquids lost. To that, experts and runners say fill up in moderation.
