Thought forumites would do there own research off the back of comments and check validity of points being made, but if you insist:
http://runningresearchnews.com/News_...?cid=1&iid=151
That page recommends 5-6 mouthfuls of sports drink every 15mins which sounds like serious overkill to me, and Tim Noakes recommends not consuming more than 800ml per hour of exercise (although he doesn't state a minimum). That would work out more than 2l for the average marathoner. Hell of a lot of fluid
Depends how big your mouth is I guess?!:w00t:
So you read the whole article including this:
As Noakes says, it is far better simply to drink according to the dictates of thirst. “As long as athletes drink according to thirst during their efforts, they will develop neither severe dehydration nor over hydration.” In a recent paper providing guidelines for fluid replacement, Noakes urges athletes not to consume more than 800 ml (~ 27 ounces) of fluid per hour as they exercise (7).
and came to th conclusion that Noakes was advocating too much fluid intake (smashes palm of hand on forehead repeatitively).
Take those blinkers off Rob
Making recommendations as to how much water (or whatever) to drink during a marathon is as daft as as the training programs in Runners World
Not only are folk running anything from two and a bit hours to six (yes, I know it's not 'running' and many of us could walk one faster, but go down to London and you'll see people waddling in after six hours), but even for runners finishing within seconds of each other their requirements / needs / likes are bound to be different
btw 2lts of water for an 'average' marathon runner in 'hot' conditions doesn't sound excessive to me (whatever 'average' and 'hot' mean)
Poacher turned game-keeper
That wasn't my conclusion, that was the conclusion of the article. It said dehydration wasn't a problem and may even be beneficial, however you'll still want to drink 5-6 mouthfuls of sports drink every 15 mins (mainly for energy). I don't have blinkers on, and I don't worry about dehydration either. I'm just pointing out that even the research you've quoted is still full of stupid comments. How is it possible for someone to advise that dehydration isn't a problem and then in the next sentence suggest you should take on less than 800ml per hour? That would be far more then I would ever take on anyway. I ran a 3 peaks recce not long ago and consumed about 500ml of fluid over 4 hrs so I can't understand how his advice adds up

That was a throwaway comment, if you add it up properly it equates to over 3litres for a 4hr marathon runner which in my opinion is excessive. I've never taken on that amount of fluid in any of my long distance events. The only time I had quite a lot was at Rombalds when I had a small cup at each checkpoint and ended up having to stop for a pee, I still reckon I only had about a litre if that.
So you consumed 500ml of water during the PPP. That is less than the 800ml water/hr the article was recommending. So whats your point caller?
To quote your own acecdotal evidence of a few fell races over the recommendations of one of the most forward thinking sports scientists of our time is simple blinkered and out of touch. He is not just plucking out these figures, they are a result of some sound studies.
As for DT's point, yes granted biochemical indifference will always be a factor, but the recommendations are per hour to differentiate and if the research helps people to enjoy and perform better as a result of taking on less water then great.
Sports drinks companies have been brain washing us for a while now.
This thread is becoming stuck in a virtual loop now
All I have been advocating is that runners in the hills should drink when they’re thirsty. And if they don’t want to drink when they’re thirsty, that’s perfectly fine by me. Every half decent article on the same subject says don’t drink to excess but drink when you’re thirsty. I just can’t figure out why anyone would want to ‘debate’ that? And what’s the hardship in carrying a bottle of water just in case?
That said I do think that carrying too much water in a bladder is equally barmy – I made the mistake of carrying a full water bladder on a boiling hot day and, due to the extra weight, the need to carry the bladder and all that water directly correlated to the carrying of the bladder and all that water in the first place, with water sweating out of me as fast as I could drink it.
Mike T has however suggested (recommended even) that there is no need to drink anything at all in a road marathon where the temperature is less than 20 degrees because your water needs are produced internally. Such blanket advice even for road marathon runners seems a bit reckless to me, given that a road marathon could take 2.5 hours for some and 7 hours for others. The key point though is that running a road marathon where there are loads of water stops isn’t taking much of a risk in the first place, given that you can stop and drink if need be. Running in the hills on the other hand, especially on your own, requires a bit more contingency planning. That is all.
