Yes I could lead the Gotham route as a night ride, I recall it took 3 hours so best to chop the Nottingham city centre bit off.
The Plank and Leggitt pub in Sawley has parking, is on the route, and is close to M1/A50, it's off-road along the Trent to Clifton bridge(A52) back out along the Trent to Barton, climb to Gotham woods, hairy descent then over to West Leake, and a road ride along quiet lanes for the last 4-5 miles.
I've always fancied linking this ride up to the Ticknall trails using the old railway trail from Breedon to make a 'Hell of the East Midlands' type 100km day out!
Give me some notice and we can do the Gotham route.
