I'm with ukhursty. I don't do long distance stuff so my longest regular run is about 2 hours but I never take anything to drink (or eat). I've been doing that for 30 years without any problems.

How are you enjoying your water DT?
Snecklifter and cock a hoop have water in them.
You don't need to drink 2 litres (whatever happened to pints) of water a day on top of your normal fluid intake. As explained in that great book, "Global warming and other BB*ll*cks". You do need around 2 litres of water total. So... that coffee, tea, coke, beer potato, curry etc all count towards your total.
On a run I count on 1/2 litre per seven miles.
I'm with UKhursty - I don't carry drinks (or food or first aid kits or whistles or flair guns or a mobile phone or toilet paper :D :rolleyes:) on runs of up to 2 to 2.5 hours in the winter scaling that down to about 1.5 hours on hot days in the summer. Theres usually water around if I'm desperate anyway; its one of the advantages of living in one of the wetter spots in the UK.
I think a lot has been made of this hydration fad. It's pretty simple really, if you're thirsty - drink, if you're not - don't.
With respect to running, it's important to realise that it takes a long time to properly hydrate from being dehydrated. So if you wee is yellow the day before a race or a training session, getting drinking - little and often. The same applies after a race.
I think someone once told me you can only absorb 0.5 litres in an hour. Any more is just extra weight.
I'm grateful to Derby Tup and Stolly for this as I really exist on tea and only use water in my camelback and sports drink on my bike, so far so good and I have raced a few deserts and had no issues. My worry is that whilst I would love to drink from becks and streams, agro pollution is a concern and so I carry drinks (and a 1st aid kit, torch, compass, map, TP and money for the phone - its a work thing!)
Who does drink from streams and how do you tell whats good?
2-3 hours without water is fine in cold or cool conditions, it's when it's hot the problems start.
