Dawn Till Dusk Challenge 100 is a new event from Charityadventure.org.uk on 30 August aimed at experienced cyclists as well as the recreational cyclist.

The route covers countryside from Horsforth in Leeds, up through Otley and Summerbridge to Ripon, over to Boroughbridge, as far as Sheriff Hutton for the 100 mile route and Harrogate back to Poole and finally Horsforth. As the name suggests the first teams will be leaving at dawn.

The Yarnbury Rugby club is the start and finish venue for the Dawn Till Dusk Challenge 100, with free camping laid on the night before and the night after for cyclists and their families. During the cycle day there is a family ride local to the club and various kids activities on the site.

Charityadventure.org.uk are well known for their organisation of long distance rides for various charities across the UK. Having just returned from a mammoth cycle from York to Amsterdam and back with 50 novice female cyclists, raising over £25,000 for Marie Curie Cancer Care, spokesperson Ginny Leonard says: "We're extremely excited about this event. It's a totally new format for us and is one aimed at the more experienced cyclists as well as the recreational cyclist.

"It is open to riders from every discipline, we have Audax riders, local cycle club teams, mountain bikers and family teams already entered. Some of the riders are even doing the ride in fancy dress! We hope to have a great weekend and attract some positive attention for Leeds cyclists in general."
