More than 500 people have registered to take part in the annual Rotary Club of Church and Oswaldtwistle Walk.
And with just over a week to go, organisers are urging more people to sign up for the walk which has raised £350,000 for charity in its seven-year history.
People can enter as either individuals or groups and organisers are encouraging entrants to dress up in costumes.
Michael Jackson, press officer for the Rotary Club, said: “Our charity walk has proved a resounding success for raising valuable funds, whether it be a national charity for example Cancer Research, NSPCC or a local group such as your church fund, local football club, scout or guide group.
“We are pleased to report that the new Mayor Judith Addison has indicated she will take part.
“So come on the people of Hyndburn and surrounding districts, support this event whether you have sponsorship or not.” The seven-mile circular walk is on Sunday, May 19 starting at 9.30am.
It will start and finish at Junction 7 near the Dunkenhalgh Hotel and covers four miles along the Leeds-Liverpool canal and three miles along the old Great Harwood railway track and surrounding countryside.
Registration is £5 for each adult and accompanied children under 12 years old walk free.
Cash prizes will be awarded for walkers in fancy dress.
Organisers say there will be plenty of car parking spaces at Junction 7 and toilets will be available at the start.
Hot refreshments will be available at the start and at various stations along the route.
