Having just got back from a trip over Weets Top to Malham, I can confirm that there isn’t much lovely solid trail out there on the moors at the moment. Disappointingly claggy and slow – no frozen stuff at all.
So you should, IMO, be looking for routes that stick mainly to decent tracks rather than grassy climbs or moor crossings.
The version of the Settle Loop John Ellison is suggesting is fairly solid, apart from the first climb out of settle, which will be soft, and the descent to Street Gate, which I’d expect to be a muddy mess.
T-d-PenyGhent should be OKish, except perhaps for bits here and there on the section that crosses Foxup Moor.
I always end up recommending this one to novices: http://www.yorkshiredales.org.uk/outandabout/gettingactive/cycling/mtb/mtb-findaroute/mtb-route-tunnelsbridges/mtb-tunnels_and_bridges.pdf
Solid as anything and good in either direction.
Only problem is it’s probably too short for a decent day out.
