Route: Birmingham to Stratford Upon Avon Canal (UK)

Classic local challenge. Get the train to Birmingham and run back along the canal towpath. Start at Black Sabbath Bridge (Gas Street Basin), finish by the river in Stratford.

Terrain: canal towpath, some tarmac, some gravel, some light non-technical trail. 

Supplies: several canal-side pubs, could divert into one of the villages the canal passes through. Plentiful at start and finish.

Direct train to/from either end. Start is 10 mins walk from Snow Hill Station in Birmingham, finish a similar distance from Stratford upon Avon railway station
