The Course

  • Run 1: Run 1 lap anti-clockwise around the Serpentine (lake) on tarmac paths- 4.0km, marked in red
  • Cycle: Cycle 8 laps clockwise of South Carriage Drive (road closed to traffic). Don’t be fooled, it’s not flat but it should be fast and the road surface is good. 180 degree dead turn at both ends – 20.8km, marked in blue
  • Due to clash with the changing of the Queen's Life Guard, there is a strict bike cut-off of 9:30am. If you have not started your final lap by 9:15am, you may be withdrawn from the race.
  • Every year a few competitors complete the wrong number of laps. It is surprisingly difficult to count to 8 as you get tired. A handy tip is to attach 8 small pieces of tape, one for each lap, to your bike frame. Peel one off at the end of each lap and when you have one left you know you are on your last lap.
  • Run 2: Run 2 laps anti-clockwise around the Serpentine (lake) on tarmac paths - 7.4km, marked in red
