Thanks all, I did the Ticknall STW route but spent about an hour exploring Robin Woods (and dodging the downpour). Some nice built-up runs in there, but weirdly no tire tracks whatsoever - all the jumps in good nick like they'd just been finished but never ridden. Weird, and a little spooky.
Rest of the route was quite pleasant and not too taxing which was great as I've got a stinking cold. Dropped onto the Cloud Trail after, headed up towards Derby then back down and round the bottom of Staunton Harold reservoir for about 6 hours on the bike.
Skulked around the services on the M1 eating everything in sight, read Cycling Weakly (sic) cover to cover then picked the kids up halfway through Iron Maiden as they had gone hypothermic (teenage girls in short shorts d'oh - you can't tell 'em).
Home around 1am so not a bad day all told!
