A group of cyclists will ride 600 miles from Bradford to its twin town Hamm in Germany for charity.
The 20 bikers are tackling the challenge in aid of Bradford Disability Sport and Leisure (BDSL).
Barry Thorne, of BDSL, said they were aiming to complete the return trip in seven days from June 8 to 15.
BDSL also held its first disability cycling club at the new cycle hub in Lister Park on Saturday.
If you would like to donate to the challenge, contact Mr Thorne via email@example.com or (01274) 437093.
