Shetland Rotary Club is inviting people to show their pedal power at a charity event to fight prostate cancer.
The club, with support from Shetland Recreational Trust and the Co-op in Lerwick, is holding a static exercise bike competition on Saturday.
The bike will be set up in the Co-op car park where competitors will be invited to pay £1 to show how fast they can cover 500 metres on the bike.
“If you’re the fastest, you’ll win a month’s free subscription to a gym at a leisure centre of your choice,” said the Rotary Club’s Paul Bendix.
“So, if you think it’s you, step up on 4th September.”
The event will run from 9am-5pm. All proceeds go to Prostate Scotland.
