DARLEY Moor hosts the sixth round of the British Human Power Club Championship season on Sunday, July 13.
A variety of human power vehicles will compete in a series of races starting at 11am.
Two wheeled and multitrack vehicles, including fully faired Streamliners and Velomobiles will compete, reaching speeds of up to up to 30mph.
It's an opportunity to 'get up close' to these innovative machines and to meet their designers, builders and riders.
The BHPC welcome entries from non-members and riders of conventional bikes.
Helmets must be worn and a £10 entry fee will be payable on the day, with registration closing at 10am.
