Runners are being urged to throw away their trainers and take part in the first Barefoot Brighton race.
The event on May 1 comes hot on the heels of the Brighton Marathon in April and is organised by the UK branch of the Barefoot Runners Society.
It is hoped those inspired by both the marathon itself and the half marathon next month will help increase the numbers turning up to take part or watch.
Local businesses could also benefit as the society is inviting people across the UK to take part.
Runners can take part in either a 1km or 5km race during the event at Stanmer Park, depending on their experience.
Anyone interested in taking part can email firstname.lastname@example.org for more information.
