    There is a summary piece by Joe Uhan on iRunFar.com this week that provides a useful summary of the science. Link below:

    I am part way through "Waterlogged" but find myself going pretty slowly through the text. Link below to the Kindle edition:

    I totally agree with that - its all about fitness for what you're undertaking. In the olden days running something like the 3 Peaks I'd be riddled with cramp, whether I'd drunk loads or not, by the top of Whernside and crippled come the finish. Nowadays I'm not which can only be down to fitness and the amount of ascent I do

    Paulo has mentioned "The Runners Body" by Tucker, Dugas and Fitzgerald.

    Tucker and Dugas are the men behind the Science of Sport website and they have a useful addition to the literature on cramping here:

    Re: Cramp – Snowdon Race.

    As a suffer of cramp in longer races 2hr plus I read this thread with interest before preparing for a long race last weekend. I decided in my wisdom it was lack of salt that was my problem so tried drinking High 5 0 a couple of days before the race and adding extra salt to my food before the race and to the water bottle during the race. However, after flying along for the first couple of hours suddenley started to get twinges of cramp in calves with still at least 2.5 hours to go by end of the race all the muscles in my legs were cramping at different times.
    So in conclusion it looks like it was more to do with muscle fatigue (mentioned in the links above) as I ran long distances before without cramp but at a much less intensity, so it sounds like need train longer and harder at race intensity to prepare for longer races pretty obvious when you think about
