I'm staying at center parks at Whinfell (near Penrith)in July.
I'll be able to get out for one day on the bike so could you recommend a 4-5 hour ride (I'm reasonably fit)that is close(ish) to Penrith.
I've got V Lake district essential trails book, so if there's something in that all the better.
I have view ranger so if you have any map files all the better.
Also is Whinlatter worth a go?
