Just south of the A50, so if you’re in Uttoxeter travelling time is short.
I’ve done the ride described on there: ‘tour of ticknall’ and the pdf for it is the one listed as ‘toughish route’
It’s not particularly techy but is pretty fast in places and there’s next to bugger all climbing, perfect for a night ride.
Alternatively I could send you a gpx for a ride starting near alton towers, just checked the map and it starts 17 mins driving north of uttoxeter, Near Threapwood quarry, parking at the queens pub: postcode: ST10 1RF. so if you’re heading south perhaps not ideal. This is my new favourite place to ride and there is lots of speed and tech and climbing. about 15 miles, 2 hours or so of riding, lots of woods and singletrack. email in profile if you like it.
And yes the chase is always open, day and night and nice easy way marked trails for pebbley fun.
