Hora, it'll be fine today, go for it! If I were you, I'd set off from Langsett car park. Go out of the gate at the end of the car park, straight across the road, onto the firetrack through the woods, take a left after a while and you'll go down a short steep bit, cross a bridge over a river, then you're on the bridleway. You'll know it's right cos it's a steepish quite interesting climb.
Just don't turn off the bridleway and you can't go wrong. Eventually you'll come to a cairn – it's the highest point on the bridleway. Chill here, take in the view, and decide if you're up for a much bigger ride or not. If you turn back and retrace your route it's a great descent all the way back pretty much, and you've an option to turn off to North America farm on the return – it's signposted.
If you decide to carry on from the cairn, you have a v long downhill with some ace technical bits, but remember on the way back it's a long and sapping climb/push….
