A few people have asked me what I ate on the Scottish Watershed Walk and how I resupplied with food. The answer is that mostly I bought food in shops along the way (my family did send me one parcel of tasty organic food from Real Foods in Edinburgh). Specialist backpacking foods can be convenient but they are expensive and have to be bought in advance and then posted ahead. Buying food in shops on or near my route was simpler and cheaper. (And also supports local communities). The picture above shows a weeks supplies purchased at the village store in Crianlarich. All that's missing are some sachets of hot chocolate.
Of course this involves some compromises and occasionally buying items that aren't that tasty (the latte sachets pictured above were pretty horrible) but overall I've been happy with this method of resupply, which I've used on other long walks including the Pacific Northwest Trail.
Above is my standard backpacking breakfast (and actually my standard breakfast at home too, though with fresh milk) - muesli (about 125 grams) with dried milk and sugar plus coffee (decaffeinated if I'm feeling awake, caffeinated if not) and dried milk. That's enough to keep me going for a few hours.
The picture also shows my stove and my two titanium pots - 600 and 900ml size.
The picture shows a day's snacks - though the dates and cheese spread would last several days.
Immediately before going to sleep I'll have a mug of hot chocolate, made from two sachets.
I don't know how many calories this diet supplies but I never ran out of energy on the Watershed Walk though I did lose 9 kilos in weight.
