Are you in a car or on a train? What sort of running? Off-road? Hilly? How fast?
Assuming train and off-road, from Airedale I’d go towards Silsden, Belton Road, Howden Road, Brunthwaite Lane, then Doubler Stones, Windgate Nick and along the crags before descending to Ilkley and getting the train back to Leeds from there. If you’re in the car you could descend to Riddlesden and go back to Airedale along the canal.
If car, the Bronte moors – the routes of the Penistone Hill country park races (google Woodentops) are all fun but a bit remote and might be pretty swampy.
Ilkley Moor and Embsay fell races are both classic routes.
