Today, I rode the Follow The Dog mountain bike trail at Cannock Chase for the first time. Great ride, and first purpose built XC trail I have tried and I love it. Brilliant twisty singletrack that go on forever, with fun bermed curves. The weather was great and the bike didn’t get too dirty which is a bonus in November. Also reckied it for some night riding but think I will have to familiarize it more before trying under lights. Did about 10 miles in total and felt nothing from my knee 
good news about the knee….. cannock chase was somewhere i always wanted to go when i was more into biking than walking
Having spent hundreds of hours between riding and walking the Chase, I must say that I enjoy riding there better. Probably because of the lack of large hills is a bonus on a bike but a minus for challenging walks.
