Yes, as part of a C2C last year. With a fully laden bike it was f*kin awful, but well worth it by the time I got to the pub! The initial climb out of Glen Desarry is on a decent trail, but quickly turns to boggy ST and, weather dependant, can be difficult to navigate on the upper reaches. Lots of burns to navigate, so you WILL get wet. I did it in torrential conditions, and the lochs at the top were way over the path on the south side, which meant lots of hike a bike, and I don’t think I’ve ever cursed as much whilst out on my bike. To make matters worse, the descent to Sourlies was partly unrideable with lots of kit, oh and you’re a long way from anywhere by this point so be careful! I stayed in Sourlies Bothy, which is awesome, as a good resting point, and was woken to sound of hundreds of deer wandering around the sea loch just outside the door….simply well worth the brutal previous day!
Next day was the short steep up and over to Inverie, probably 3hours in total. Push up followed by one of the best descents in the highlands! BTW in sept last year this area was infested by ticks, and I reckon I pulled 30-40 out of my legs on that last climb-so take a remover and/or where longs for this part. End up at The Old Forge for well deserved pints
