I did not drink from the fells, but splashed myself and dunked my hat several times. I was thirsty, but know from experience that I can cope with 5% loss of body weight in hot conditions - based on a 20 mile run on a day in the high 20s, having weighed myself before/after and having eaten/drunk nothing during the run. I know it is not recommended to go beyond 2-3% weight loss. Dehydration is not the same as heat illness - the former slows you down and eventually stops you - the latter can kill. Heat illness is uncommon in recreational events where participants can set their own pace and decide on intake/clothing, though vigilance is necessary, and occasionally the worst can happen, even in those who are experienced. Hyponatremia from excessive drinking is a real risk in long road races with frequent drink stations, but is less of a threat where people have to carry there own supplies.
