I'd be up for it. I think Lewis posted up about doing both days in the Lake district a while ago? I'd definately do the saturday 10k, not sure i'd fancy repeating the same course with an additional 4 mile fell run at the end on the sunday!
Thanks for posting Fiona! Our 2 friends have messaged and said they'd prefer the Lakes one so they have more time to mentally prepare but we're easy either way.
