Human Race strongly discourage the use of any equipment that acts as an impediment to hearing or concentration when competing. This includes, but is not limited to, mobile telephones, personal stereos and MP3 players. Human Race cannot be responsible for accidents resulting from taking part with such equipment.
If you do decide to run with headphones please ideally only use in one ear and keep the volume as low as possible, and please also ensure that you look around you whenever changing your direction on the course or running around someone. With limited hearing your understanding of runners around you is reduced, so please pay attention to prevent any collisions with your fellow participants.
