If you’re in Ribchester you’re very near to Gisburn, would make sense to ride there Sun eve. Take a route map though, some of the sign posts aren’t guaranteed to be there! Then maybe head over to the Lakes for a ride on the way back Monday.
I really wouldn’t recommend riding any of the more remote Lakeland routes in the dark if you’re not familiar with the area.
Kirkby Londsdale would be a good place to stay in between. You should be able to get a room+breckie at the Blue Pig for about £50. Avanti do good pizza to either eat-in or take-a-way & are reasonable. Alternatively there’s loads of accommodation in Kendal, or head over to the Mill Yard car park at Staveley to kip in your van, breckie at Wilf’s cafe, then pick one of the many rides from there..
