Laggan Red has drops? Just get off and walk them…
Burmah Rd (original circuit) is good as a training run and it’s a big old climb but little more than an Estate Road bash tbh.
Some nice singletrack from Inverdruie>The Polchar (unnamed Lochan)Loch and Eilein> Loch Gamhna (East side)> on to Feshiebridge > Inshriach Forest and a whole bunch of way marked trails above Uath Lochan. Great views from the top. Loch Insh watersports centre does a decent pint / pub food. You cant really get lost in there so don’t worry too much about map reading.
Further over that way you can chain gang out to Auchlean, head South on the Singletrack East side of the Feshie then East on the Estate track before Ruigh-aiteachain bothy, bag the Munro Mullach Clach a Blair (circa 700m vert from the Glen floor and all rideable if you’ve got the legs / lungs)then double back on yourself over Carn ban Mor and on to Sgor Gaoith. Now we’re talking views 😉
Once up on the plateau it’s all easy riding. Descent is via the Foxhunters Path to Auchlean (Northern most of the two you see on the map after the trail splits)Quite technical in places but no shame in getting off and walking – esp if you are on your tod. You can park up circa 1 klik before Auchlean if getting out and back sounds too much. Don’t even think about Sgor Gaoith et al in anything but clear visibility if you can’t navigate.
Another: Glenmore>Ryvoan>Coire Odhar>Fords of Avon>East Glen Avon (few tech pitches but nothing really hairy)Inchrory>Dalestie>Torbain >Tomintoul>Kylnadrochit Lodge>Dorback Lodge>Braes of Abernethy>Ryvoan>Glenmore
