Golding Barn does not do bike hire. However the Yamaha School (see elsewhere in the forum) does provide you with bikes etc to ride. They use Golding Barn as one of their tracks.
It really can be a blast to do for a day.

+1 for this
Did the BMW off-road thing in Wales, would be good to try off-roading on something a little lighter 
Will need bike + kit hire tho.

Ive managed to obtain a discount for Track Sense. Will post a poll thread with details.
I bet them pig-tails were swishing;)
