Some options for you.
An 30min add on would be, drop into 3 shires head as normal.
Cross the bridge and turn right. Climb up (can be a bit tricky in places, for me anyway).
Carry on past the cottage and through a gate, ride around the left hand bend with the motorbike trails rocks on your left. Climb up the road to the triangle junction and bear left, still climbing. At the end of the road turn left down a track just before the farm (Knotbury farm I believe).
Descent to the gate turn left, continue along the path, getting gradually steeper and rockier. The brings you back to the 3 Shires pack horse bridge.
Another great extension, this is best done in the week, certainlty not at the weekends or bank holidays (ie cheecky/footpaths)
When you reach the cat and fiddle Road turn right as normal and then left into peaks view cafe entrance. Climb right up the grass bank, at the top turn left, continue, over the style and keep going, decending keeping the wall on your left. The path eventually bears right away from the wall. Follow all the way, through another gate and at the end bear right, continue to the road.
Choices – Option 1. turn left, then next road left, climb all the way to the to. Here carry up and over the style. Climb up on the path, which beacomes flagged all the way to end (Shinig Tor). Descend down and up. Over the style and turn right. You are back where you were earlier. Above the Cat pub/Peaks cafe. It’s quite a long and tough climb, but a very enjoyable one.For referance Strava has it as 3 mile and 800+ft climbing.
Option 2 (easier) At the road turn right and ride up to Deryshire bridge car park,plesant ride through the Goyt valley. At the end turn right and climb up the road. This lead up to the cat and fiddle Road, just below the pub.
