Absolutely.
Assuming you start at the Pub in Litton then Arncliffe, Malham Tarn, Malham (watch descent!), Kirkby Malham, Airton, Hellifield (watch main road jcn!), Halton West, Wigglesworth, Settle (stop for a cuppa), Stainforth, Halton Gill (watch cattle grids if wet!) and back to the pub in Litton where the food and beer is good.
Probably not quite 50m but you'll know you've done it. If it's windy and cold the tops are very exposed so take an extra layer.
