24hr 3-peak attempt: driving itinerary, drop-off and pick-up

[Grinning]

As the title suggests I am looking for the optimal driving itinerary for a 24hr attempt on the 3 peaks: including set-down and pick-up points at each of the peaks. Plan is:
Day 1 - set off from down South, overnight around Carlisle
Day 2 - Carlisle to Fort William
Day 3: Ben Nevis, then off down to Scarfell Pike, then Mt. Snowdon.

Anyone able to flesh this out at all?

Cheers from the designated driver...
