Route information
The course will be clearly signed for the specific event that you are doing:
  • Green: signs and tape for the 6k course
  • Yellow: signs and tape for 10k course
  • Red: signs and tape for 21k course
There will be coloured tape every 300 to 400 metres. Re-trace your steps if you have not seen the tape for more than 400m.
This course is a mixture of trails and road with open water swimming. Make sure to enjoy the fantastic mixed-terrain run through woodland and parkland as your cruise along the undulating course. The varied courses will be clearly marked with the colours indicated above throughout. Make sure to follow your specific course and not other competitors as they may be in a different race to you. When competing try and keep a 2m social distance, especially where the course cross paths. All races will head along the shore of the Bewl Water reservoir. The 6k and 10k courses will head back towards the finish throughout, whereas the 21k course will cover a longer trail with quiet roads and steep hills in and around the nature reserve. Be warned, the end of the 21k race will be specifically demanding so make sure to conserve your energy.
