I ran the affric-kintail way starting from Morvich and ending in Drumnadrochit. It was a beautiful day out, the trail was very wet and muddy in most places because of recent rains. I ran it completely solo and unsupported, carrying all my gear and food, and filled up with water from the many streams / rivers along the way. My husband dropped me off at the start and then drove back to Drumnadrochit to drive me back home at the end.
It's a beautiful trail, especially the first part from Morvich - Glen Affric which feels quite remote. The trail then becomes more of a forest track and you're closer to civilisation once you reach Cannich. The trail is well marked, and very 'runnable' in most places (minus the river crossings and skirting round bog!), I'd recommend it to anyone seeking a good day out on the trails.
