Hydrate..hydrate ..haydrate but not to much.There's a new study that runners(applicable to us Mt bikers) who drink to much water/any kind of fluid during period of heavy exertion can be dangerous or even fatal due to a condition called Hyponatremia(Low sodium cocentration in the blood.The study said that too much fluid intake(including sport drink/gatorade) during period of exertion can delute the sodium content in the blood which lead to Hyponatremia.Hyponatremia can cause swelling of body tissue including the brain that's why dizziness and nausea is common after a long ride.Ideally ,a rider should lose weight after a ride but if you gain weight after a ride there's a possibility that you over hydrate yourself.So' you can measure your fluid intake by checking your weight before and after a ride, drink only as needed and check how much fluid you consume."drink as needed" ;D
Not exactly,but you can measure the amount of water you drink by checking your water container before and after the ride.The point here is to drink water as needed during period of heavy exertion and to make sure that you dont gain weight after a ride.
