The C51B starts on the A950 in Longside and follows Coopers Brae west. After a dog-leg across the C39B by the church, it contiunes south west along Inverquohomery Road, leaving the village behind. The A952 is crossed just beyond Yokieshill, with the road climbing a gentle hill. After the summit, it drops a little into Stuartfield, following Knock Street to the B9030 in the centre of the village.
