I was talking to shaggy, endurance rider par excellence the other day about food for long (100-200 mile) stretches of trail with no chance of restocking. I’d been working the supplies I carried on my LEJOG trip in terms of calories per pence as I was on a fixed budget per day. Shaggy thinks of food in terms of calorie density, not just how much it weighs, but how much space it takes up.
Dried carbs, are pretty shit on this count as you only get 4 calories per gram, and each gram takes up quite a bit of space. Also factor in that you need to carry or find and filter (water filter takes bulk and weight) water to cook them, and also to carry a stove and fuel to heat the water. Also this all takes time. Stop, unpack, find and filter water (if necessary), boil water, cook pasta/rice, eat, clean pans, repack, get going again.
Turns out my LEJOG diet was closely matching that shaggy was looking at for his long distance races.
For the same calories per gram as dried carbs I was carrying 200g lumps of Cathedral city cheese, 806 calories (403/100g). Entirely protein and fat and no carbs (even if not iDave friendly). It takes up less space than the same room of rice/pasta, needs no water, needs no heating, and can be eaten without stopping.
200g of chorizo provided me with even more energy density at 500 calories per 100g chunk. Again, protein and fat and no carbs. Again no need to carry water/filter/fuel/stove and can be eaten without stopping.
My last snack was 100g bags of peanuts, which are even more energy dense, over 500 calories per 100g, again no carbs.
And before anyone says you need carbs on long rides those three items above and a fry up breakfast sustained me for 10 hours and almost 90 miles on the last day of my LEJOG into a howling northerly gale (7mph pedalling on the downhills), without bonking, cramps, or the bloating that I’ve suffered when I’ve used carbs for fuel in 12/24 hour races.
On the one day I made the mistake of buying tiffin as a ride snack I bonked after just 30 miles and only recovered after I’d had a KFC.
