That sounds like a tough day out using the bike....I take it that it was not an battery assisted bike
that would be a really tough day out. I do use a bike when out but just to reach where I want to walk uphill from. The only time when I carried a bike, years ago, was to reach the Corbett Leathad an Taobhain from the end of the estate track before continuing along the Minigaig to Bruar and into Glen Tilt, and then onto Geldie and back into Feshie.
My daughter does the carrying of her bike on occasions to get to a cross over into another valley? You folks seem to have your own system for getting the bike onto your shoulders for a carry.
