IMHO it is too far to drive for the ride you will get
you really could get to the lakes in the same time as Gisburn takes ages to get to from that side- It will take at least 1 hr 30 mins to get there whatever the sat nav says IME
I would ride Rivvy for natural – can sort you out routes if required or drive to stavely and ride there.
There is very little swoopy stuff on the blue at gisburn though I only did it about two years ago so other will be better informed. Kids walked the first bermy bit I think and it took us a lot longer than 1 hr 30 to ride
There is a cycle route along the prom from Blackpool to Fleetwood and a decent BMX track in Stanley Park
