Ah, this is fresh in my mind as I’m just back from the European Adventure Racing finals, which was a 72hr non stop race including lots of biking as well as running and kayaking. I was fuelled on a variety of the following, with the aim of ingesting 250 calories per hour, heavy on carbohydrate. It was a mix of sweet and savoury stuff, as you can’t survive on just sugary crap for that long, you start getting mouth ulcers and stomach issues.
Clif Bars (lots of)
Peanut M&Ms
Clif Builder Bars (protein)
Clif Shot Blocks
Ham and cheese tortilla wraps
Clif caffeine gels (double espresso ones are rocket fuel!)
Cashew and peanut mix
mini babybels
pepperami
jelly babies
flapjack
mini pork pies
nutrigrain breakfast bars
Rego recovery drink (powder mix)
Nurishment drink
A couple of dehydrated meals, eaten in transition.
Admittedly I’m now completely fed up of all of the above, having eaten one or other of them every hour for 72 hours, but they did the trick fairly well.
Stuff that others had that I was jealous of:
chocolate (simple but effective)
mint cake
cake (one team stopped at a WI cake sale and loaded up!)
cold pizza slices
sausage roll
