Planing to go for a run from Marley park to Crone woods and back. WIll have with me a litre of water, but somehow thinking that will not be enough. Thank

Water is your life blood and not a pschological crutch. The Isreali army famously tried to see if the human body could adapt to dehydration back in the 90's so that the military would have an advantage in desert warfare. They employed this tactic by water rationing and cutting down on amounts of water given to troops. The experiment was a disaster that they kept on pushing through with until it ended up with many deaths.

I've seen people running 5Ks with water because they thought they needed it and on the other extreme there is Enduro - the difference is in the mind. As for that Israeli study, I cannot find anything about it on the internet. Surely if there had been a study that caused "many deaths" the references to it would be all over the place. Have you got a link?

Because in a marathon there are water stations at the side of the road every 15 minutes, no planning or carrying required, and in a marathon you are running at maximum effort, working harder than on a training run.
Safiri wrote: » Enduro is talking about physiological response and not how handy it is. Taking on water is beneficial and there is no adaption to abstinence, then there is no reason to purposely avoid it. TFBurbendorfer: check out water discipline in the Military. There are no published studies because the Military does not publish to the Journal of Science etc. Many other countries have tried the same thing only for the experiments to be ceased. The data collected on degradation of performance was enough during the experiments that all the militaries now take a strong stance now to ensure that all personnel remain hydrated.

TFBubendorfer wrote: » I can give you 2 examples from my own personal history. In 2013 there was a heatwave in Ireland with temperatures over 30 degrees in July. We happened to run a few marathons at the time. The organisers did their best to keep the water going but there were a few aid stations that were dry when we passed. Some people could not handle it and dropped out. Others just shrugged their shoulders and got on with it. It certainly wasn't ideal but we finished our races, and nobody suffered from any ill effects. The other one was a race in Greece in 2015. Temperatures were 30 or 32 degrees, depending on who you ask, and very high humidity (it had been raining the days before and again the following day). Despite very frequent aid stations, about 2 miles apart, you invariably got thirsty in-between. Some people just could not handle it. None of the runners who dropped out in either situation were so badly dehydrated that they would not have been able to continue. It was their heads that went first.
Halloween Jack wrote: » So you actually think that first example, a freak heatwave coupled with organisers failing to supply water stations is worth spending any time preparing for or training your body to adapt for? As you said yourself, a couple of hours running in Ireland is hardly likely to leave you dehydrated in the vast, vast majority of cases. In the second instance, I’m not sure how you could be dehydrated at all if you are taking on water every 2 miles and had been hydrated at the start of the race?

Handy if you want to run all way to Glendalough. Which you should. It's amazing. I believe you can certainly adapt to using less water, whether it's a mental/physical issue.

The obvious places are the two rivers you cross. Unfortunately both would come with a potential health warning as there are sheep in the vicinity. The other udder option is a water drop in Crone that morning or the day before.

I take the point about energy drink companies setting up the question in a slanted way though. My own highly personal anecdote (based on short multisport races of 3~4 hours duration) is that 2x750ml bottles of energy drink company water PLUS dioralyte sachets are the perfect formula to get me to the finish line in good condition. Highish intensity exercise over 3 hours does work better with fluid intake, in my opinion.
