ride north up the east side of the River Lickle (forestry track officially a footpath) and then come down the scorching singletrack bridleway on the west side of the river, back to Stephenson Ground.

If you keep your eyes peeled, there’s a little track that leads left off the forestry road just before it kicks up sharply. This crosses a small bridge and lands you on the bridleway descent just where it starts getting less nadgery and more full tilt. Handy if you have less experienced riders with you.
Then head round on the bridleway towards Carter Ground and skirt over toward Hoses to join Park Head Road near its start and pick up the route as before.
If you’re on the last day of a stag weekend and dying by this point, you can quit early and take the bridleway back to Stephenson Ground, from whence you retrace your steps.
