The one I usually recommend in this scenario is Pooley Bridge on the N E corner of Ullswater.
I realise it is not a TC, but it is excellent and close to M6
Up the road/ track to cockpit
Lovely mellow descent to Howtown. Couple of bits around Martindale
And if you’re really up for it then lovely challenging Bridleway up to Boredale Hause then an excellent descent to Ullswater. Refuel then to the excellent ( but damn techie) Ullswater Bridleway back to Howtown, then road to Pooley.
Excellent route ( caveat Volvor: this usually means challenging and engaging when I say it ,;-) )
