i just joined cross country. normally i only run 3 times a week and not in a row but practice is every weekday. after practice on thursday, i went home and puked. i was really thirsty while running, so i don't know if i was dehydrated, or maybe just working myself too hard, or maybe it had something to do with the fact that it was my time of month. does anyone know what the cause could have been or how to prevent it?
thanks.
