Thanks. That does sound like any interesting route 13thfloormonk, does that start along the private road towards the bothy by Ben Alder, but stay on the main track before the bothy turn off? Sounds like it might be one for another day!
Planning on doing it in May, so will take some basic lights, but would hopefully be close to Inverness by the time I need them (if at all). If I can average 8mph inc breaks, that would be 10hrs, so even accounting for faffing about, breaks etc, hopefully I could do it by sunset.
Flatfish – the train I was looking at to FW is the sleeper, which gets in at 10am. The advantage of doing it to from FW to Inverness is that you have the prevailing wind behind you (and a nice flat section to warm up!)
