Same as the Half and 10k route, but proceed beyond the Half Marathon turnaround point up through the path onto the main A499 road and follow the footway into Abersoch.
Cross the road at the village centre and onto Lon Traeth which leads you onto the main beach. Proceed along the beach towards a car park at the far end at Machroes. Take a right turn before the car park and a short uphill section along a minor road before taking a left turn. The minor road leads you onto a gravelly road where after a short climb you take the path to your left through a kissing gate. The path leads you along the Porth Tocyn headland and towards Porth Ceiriad.
Follow the path onwards around the Cilan headland and drop down onto Porth Neigwl, follow the path just above the beach where a right turn will take you to the main beach Car Park (feed station). Take a right when exiting the car park and follow the minor road which leads to the village of Llanengan. Take a right at the crossroads and follow the minor road to Sarn Bach.
Take a left at the junction and head down to the beach to follow the same path back to Pwllheli
