Thousands of people will be stepping out for the annual Crazy Hats walk on Sunday.
Cash raised by the five-mile event taking place at Wicksteed Park will help improve breast cancer care at both Kettering and Northampton General Hospitals.
Charity founder Glennis Hooper said: “If your life has been affected by breast cancer in any way please join us on this day in support of our appeal to continue to enhance all aspects of breast cancer care in Northamptonshire.
“It is wonderful that over £2m will have been raised after the walk and we thank everyone for getting us there, but our work and continued support must go on. I can promise everyone taking part will feel so uplifted.”
Bernie Keith from Radio Northampton will be opening the walk, which starts at 10.30am.
Walkers can enter on the day, but are urged to arrive early.
MPs Peter Bone, Philip Hollobone and Andy Sawford will be attending the event, as well as the mayor and mayoress of Wellingborough, Andrea Slater, the UK president of Avon, which is the walk’s main sponsor, and Oliver Wicksteed.
Glennis said: “Life here is somewhat crazy but everything is going well. We are praying for good weather, but we’re ready.
“We are hoping to match last year’s numbers and, dare we say, reach that magical 3,000 total - it can be done.”
“We are looking forward to seeing a wonderful array of hats, and there will be entertainment throughout the walk.”
Prizes are up for grabs for numerous categories, including craziest hats, largest medical team, largest youth group and the dog wearing the craziest hat.
An awards night is being held on Friday, March 27, in the park’s Celebration Suite.
