The public are being invited to bounce their way across the Tay Road Bridge for charity.
The Cystic Fibrosis Tayside group is hosting the event to raise money to help those who live with the condition.
The event, on September 1, will involve bouncing your way across the 1.4 mile bridge, from the Fife side, on space hoppers.
If you raise a minimum of £30 you will be invited to take your space hopper home as a keepsake of your challenge.
