What everyone's reading
The research, carried out at the University of Cadiz in Spain, had 16 active men run for around one hour at 60% of their VO2 max in a lab at 35°C. In the two hours following the run, participants either consumed mineral water or up to 660ml of beer as well as water.
In both groups, body mass decreased following exercise and increased in the rehydration period, with negligible differences between the water-drinking and beer-drinking groups. No adverse effects were found on other measured perimeters such as fluid balance and body composition. The researchers concluded "We could advise those who regularly consume beer after sport or are physically active in the heat that a moderate intake would not alter the recuperation process."
If that's not a sign that you should start ending your runs at the pub, we don't know what is.
