In reply to Luci:
She's willing to cycle up from Cambridge to meet you? And then you're cycling form Edinburgh to the hills? And THEN you're cycling in to do a hill? That's commitment!!!!
Ben Alder area - bike into the bothy/s and stay a couple nights, do some hills, bike back out.
Ben Lui from east at Dalrigh.
Multiple options in the Tolmount area biking in SE along Glen Callater
CMD Arete and Ben Nevis, bike up the path to the CIC hut (one of the best singletrack descents in UK if you ask me!!)
Just a few options!
Cheers,
Gordon
