Rode it a week or so ago. It’s currently approximately 1/3 ace, 1/3 **** mental and 1/3 bog. You start off down a fairly swampy channel that turns into a nice rocky chute to a gate. Past the gate it gets rockier until it turns into a seriously savage set of switchbacks, massive rocks all over the shop, no obvious lines, I was off and carrying the bike. Then there an awkward stream crossing, and a very techy traverse across a 45 degree landslip above a big drop into a gully, pretty nasty if it goes wrong and very easy to make a mistake. Then there a nice bit of rocky singletrack, some not-totally-insane-but-still-quite-stupid techy bits, more rocky singletrack, then a massive swampy rutty bog-fest down to a gate and across the river. There’s no bridge but you jump over on rocks to find one last nice bit of singletrack traversing the other side of the valley to a final gate, and then it’s landy track down to Glossop.
It’s not actually a bad bit of trail as such, but I’d leave it for a nice day after some dry weather, and don’t expect to ride the whole thing (if you do think you’re going to be able to ride it all please take a Go Pro and upload it so we can see how you did it/have a good laugh). 😉
