Under UKA rules, headphones are no longer permitted in events that take place on roads open to traffic and runners risk disqualification if spotted wearing headphones with the exception of bone conducting headphones. Headphones are permitted for events taking place ‘off road’ or closed to traffic, however you must be able to hear the marshal’s instructions and other runners around you. Some race organisers will often use their own discretion and ban headphones of any type. As the allowances for headphones differs from race to race, details of this will be included in the race-day information emailed to all participants a few days prior to the event.
