The original track at FJ has been modified a lot over the years but still starts at the same place at the top of the hill! The top section of the track is used for all but the night race event with various junctions and diversions following the bog bridge crossing. The lower woods are known for being tight and rooty and have the power to unsettle without any warning (as I have often found out!).
