Mountain Biking 4:23:00 [3] 54.1 km (4:52 / km) +1000m 4:27 / km
A bit of an MTB adventure. Loop starting in Blair Athol, up Glen Tilt past the Falls of Tarf then more up to Fealar Lodge and back through the very empty country of Gleann Mhor, Glen Fearnach, Glen Lochy and Glen Girnaig with a couple more significant climbs on the way.
This is called a classic MTB route, although some of the comments are that it is not sufficiently technical - seemed technical enough for me and wonderfully remote.
