Land's End to John O'Groats penny farthing cycle ride
Cyclists are being invited to mount penny farthings, tandems and circus bikes for an alternative charity ride from Land's End to John O'Groats.
Leicester charity Cyclemagic is aiming to raise funds for the development of its disability cycling project.
Organiser Roger Lovell said they expected to "cause quite a stir" along the route.
The ride will start at Land's End on 2 October and is expected to take about 14 days to complete.
'Guerrilla bike festival'
Cyclists can join the route at any point during the ride, which will cover over 1,000 miles and include a "scenic" diversion through Leicester.
"It's going to be fun but quite hard work, especially in hilly Cornwall. We expect lots of swearing," said Mr Lovell.
"We're likely to cause quite a stir along the route. We expect it to be like a guerrilla bike festival in every town we show up in."
The charity is hoping to raise £25,000 over the next three years to help meet the increasing demand for its services from people with disabilities across the UK.
It costs about £5,000 a year to store and maintain its fleet of specialist cycles, which is currently funded through the charity's commercial work selling, building and refurbishing bikes.
The not-for-profit group also builds and modifies bikes to meet the specific needs of customers for a subsidised fee.
