On Sunday 3 November 2019 at about 11:30am, I was near the end of my ride whilst riding up Lower Roller Coaster Road/Interval Hill (where there are cows and 2 big sheds on the right hand side) about to turn right onto Venice Canal road (a single road with a single track on the right). As I was near the top of Lower Roller Coaster Road/Interval Hill, a young guy with a white top and hoodie approached me. He removed his hoodie and came towards me with a knife. I managed to turn around and accelerated back down the hill (from where I came) and the young guy started to chase me, but I managed to get away without any harm. I would like to bring this incident to the attention of the mountain biking community, so that you are all aware of this security risk when riding at Northern Farm by yourself. My suggestion is not to ride by yourself, so as to reduce the chances of this happening to anyone else. Anton
