Start three quarters of the way (left to right) along the large painted white take-off line located 125 yards from the SE end of the main NW/SE runway. Proceed NW along this runway, sweeping right after 100 yards to join the NE part of the other main NE/SW runway. Follow this to its end at 900 yards, taking the third sweeping taxiway on the left. Follow this back round SW and then turn right at 0.75 miles on to a smaller concrete taxiway in a NW direction. Stay on this taxiway 0.6 miles until a sweeping left curve turns 180 degrees all around the NW end of the NW/SE runway, crossing it at 1.5 miles, before returning another 0.6 miles on the other side. The taxiway sweeps right onto a larger area of tarmac (2.4 miles). Soon after turn right and then left to loop through the first of 3 old hangars, before turning left and left again to turn 180 degrees and retrace the same taxiway to the centre of the main NW/SE runway at 2.9 miles. Turn 90 degrees right to join it, proceeding in a SE direction to the intersection of all 3 runways at 3.2 miles. Half turn right to join the main NE/SW runway in a SW direction. Follow this almost to its end (keep on the right side) and take the second taxiway exit on the right (4.0 miles), then keeping tight left to turn 180 degrees and rejoin the same NE/SW runway in the opposite direction (keep right). Take the first taxiway exit on the right at 4.5 miles and follow it back to the start at the SE end of the NW/SE runway (4.9 miles), where turn left onto the runway again to crossing the white painted takeoff line (5.0 miles). Repeat for second lap, the finish is when you cross the white painted takeoff line second time round (10.0 miles).
