Can anyone tell me where they are and a postcode please, also how would I best find the downhill?

Leave oswestry via willow St. Head up past the fire station. Keep climbing. High as you can go. When you reach the top of the hill there will be a crossroads before the road drops down again. Turn left. Park on your right in the car park for the “racecourse”

Head left on the racecourse. Follow the open land round to the right. You’ll see a stone horse with two heads. Left of that is a footpath (Offa’s dyke) head toward the tree line behind the horse and behind the trees is the down hill area.

Been a while since I did that DH, there are some bits that can catch you out. Steep in places with some fair drops/jumps. There are a few other tracks around Candy woods, always good for a quick evening blast.
