I love a one way run. Just feels more like a journey that way. 
So having  dropped a friend off at Crianlarich early doors I hopped on the train to Bridge of Orchy and ran back on the West Highland Way. The WHW is popular for a reason - it's an awesome bit of the world to move through on foot.
Feeling good,I kept going, thinking I'd never seen the Falls of Falloch despite driving past lots. 
A little ankle cruckle slowed me down /made me sit down and try not to throw. As the pace dropped, the snowy rain + a few stops to ice the ankle in the burn was cooling me down quickly. 
Turned for home still pretty happy with a decent run out and the seeds of a big adventure sown.
