I'm setting off on a section of the Great North Trail on Sunday (leaving Haltwhistle and ending at Muir of Ord) and the section from Killin to Fort Augustus is currently looking a little bit challenging logistics wise (~150 km without resupply option). I've bought some dehydrated meals which I want to pop into a parcel and post ahead of myself. I've heard of various people doing this kind of thing on the Cape Wrath trail, however the post office website is pretty unhelpful about whether or not this service is offered at the Killin Post Office.
So, good options for posting some dehydrated meals to myself to help lighten the load a little bit?
