Gravel Riding in Lake District

I as m going to the Lake District (Ambleside) next year and will be taking my Gravel bike. Can anyone recommend some good gravel riding loops? 2-3 hours riding would be great.
Thanks.

There’s a ton of amazing stuff! From Ambleside I’d probably down to Grizedale forest for miles of fireroad, then up and over Parkamoor and back around.
