I did the Tour du Mt Blanc 2 years ago and was warned that each food stop would have lots of different sorts of food. At first I felt really spoilt for choice, and tried to grab a bit of everything, but after a couple of stops I started to avoid anything dry, and found that in the night sections I would choose a cup of minestrone soup and a slice of bread to dunk in it - soggy bread slips down a treat without chewing (I get a really dry mouth on ultras), and the soup was warm and salty, with a bit pasta.
Later in the race I'd also developed a craving for sweet black coffee and also coke (which I don't usually drink) - must be sugar and caffeine. Coke is better flat or slightly flat, and it can get shaken up inside when running - with unpleasant consequences.
Early in the race and before my mouth dries out, I'd like a marmite sandwich.
Thanks
