I took the upper road in October 2018. It had 4 or 5 gates in it, the kissing gate type, but very tall (too tall for me to lift my scruffy mountain bike over it). I could get my mountain bike round the V-shape of the kissing gates by putting it upright, in all cases but the last one. At that last gate, I then parked the bike and walked on. (I hadn't realised that the lower road didn't involve that kind of obstacle race, or I would have taken the lower road!)
