The Chilterns Cycle Challenge is set to take place this weekend after being delayed by bad weather.
The ride, in aid of Iain Rennie Hospice at Home, will see cyclists tackling one of three routes taking in rural roads around the area – 10km, 35 miles or 75 miles.
It was originally due to take place on March 24 but had to be postponed because of treacherous icy conditions.
Organisers are hoping the weather will be better on Sunday, when riders will start and finish in Kingsbury, Aylesbury.
Registration for the 75 mile route opens at 8am for a 9am departure, while the 35 mile timings are an hour later. People can register for the 10km family route from 10am and it starts at 11am.
The rescheduling means Fern Britton will be unable to attend, but there will be music, refreshments and stalls in Kingsbury to keep people entertained.
Last year’s event raised more than £40,000 and with the success of Bradley Wiggins and Team GB since then, it is hoped this year’s total will be even bigger.
Registration for the event is open and costs £15 for adults with cheaper prices for children. To register call 01442 820740.
