A good run on the fells start in Glenridding - Glenridding Dodd-,- Heron Pike,-Sheffield Pike,- Nick Head, Hart Side-,Stybarrow Dodd-, Sticks Pass,- Raise, Whiteside,- Glenridding Valley - Glenridding
That will give you around 10.75 miles and about 3,650 ft of ascent, tis a nice little outing.
For road and given that you are doing SNOD Mara this year I reckon a run up KIrkstone Pass and return, with parts of it being 1 in 4 gradient it would give you a reasonable workout TBH it would almost Replicate the first few miles of SNOD mara from Nant Peris to the summit of The pass, but with the Bonus of the Kirkstone Inn at the summit rather than a youth hostel.
If the road is to busy there is bit of a trod at the foot of the hills to the right as you are going up.
Enjoy the Lakes whatever you choose.
