Being a local I haven't been up on Good Friday for a while as i could go up anytime, but :
They mostly just walk up to the Pike and back down.
Depending on where people have parked it can either be a decent walk or not worth bothering with.
There's another hill about 1/2 a mile away called 2 lads that uptil Covid no-one bothered with.Then there's Winter Hill which is the highest point of the Moor at 1500ft.
On the Saturday there's a fell run from the Crown in Horwich up to the Pike and back again.
Most of the route is rocky and I always hope the runners haven't gone over on their ankles.
There are hills and mountains all over the UK (and beyond probably) that are traditional and most of us haven't got a clue why.
Cat Bells nr Keswick is busier than Blackpool sometimes and nearby Barrow Fell has half a dozen on it
😕
