Men, women and children are pulling on their walking boots to help raise cash for medical research.
About 300 people are expected to join the Foxtrot charity walk on Sunday
It will be held in the grounds of Ratcliffe College, Ratcliffe-on-the-Wreake from mid-day.
Participants can walk anything from 600 metres, up to three miles on flat ground, depending on fitness and enthusiasm
Doctors from the University Hospitals of Leicester NHS Trust will be joining patients, their families and friends for the event to raise funds for orthopaedic research.
Richard Power, a consultant orthopaedic surgeon at Leicester's hospitals, said: "We are aiming to raise a total of about £25,000 for equipment which tests material strength.
"It will help test the strength, for example, of cement used in joint replacements, metal rods used in some procedures and to test different tendon repairs.
"This will help us in research into how we can treat things in different ways. Orthopaedics is all about the strength of the things and this equipment will help both in researching the best materials and techniques.
"It will also help us with teaching in the work that we do."
So far, about £12,000 has been raised for the equipment.
Mr Power, who will be comparing the event on Sunday and leading the walks, said: "This money has already come in though donations.
"We have a very good and a very loyal band of patients and supporters."
People are invited to take a picnic and there will be a variety of activities for families and those who want to support the event but do not want to take part in the walk.
"These include a bouncy castle for children, a cake stall and a raffle.
There are also plans for a jazz band to provide entertainment for the crowd. The sponsored walk has been held every other year for more than 20 years. People can turn up on the day, but those who want to take part must register between 10.30am and 11.30am.
Proceeds will support the Orthopaedic Department at the University Hospitals of Leicester NHS Trust. The event, which is run under the umbrella of the Leicester hospitals charity, is due to finish at about 2pm.
