Depends what you want – grassy slopes, big angles and stupid speed = Howgills (there are some decent shortish loops that can be done around those parts, the descent down from The Calf past Winder and back into Sedbergh is just epic, and pretty easy for those used to groomed trails)
Going into the Lakes is just a complete pain in the arse at the moment. If you aren't fighting tourists it's floods! Slow going 🙁 That would suggest either around Kendal/Stavely or along the A590 for Grizedale. I would be tempted to go for the latter myself, but I aint done much in the Kendal area as yet!
