More than 20,000 people are expected to descend on Cardiff Bay this Sunday for the Sainsbury’s Sport Relief Mile.
Cardiff Bay is a hub of activity as the city prepares for an influx of runners, well wishers and tourists.
Stuart Higgins, events safety officer for Cardiff City Council, said: “Everything is running smoothly right now. We are setting up here in the basin and it looks like Sunday should be a great day, and it’s all for a good cause.”
“We will be here first thing on Sunday morning doing last minute preparations - provided I put my clock forward on Saturday night.”
When asked if he was hoping for good weather, Mr Higgins said: “We know we are getting good weather, we have already booked it!”
Those taking part will be joined in the run by some famous faces, including Goldie Lookin Chain, Gethin Jones, Danielle Lineker and Gareth Thomas.
The day will start at 9.30am and Cardiff Bay will feature Cardiff Blues inflatable football pitch, magic street theatre, face painters, Rock Choir, and a samba band to spur on the “milers” and entertain the crowds.
All money raised by the people participating will help people in Wales, Britain and with some of the world’s poorest countries.
Cardiff council is working in partnership with Sport Relief to deliver the Cardiff Mile.
Bryan Osbourne, a retired police officer, has worked as a tour guide for nine years at Cardiff Bay Tours. He said: “I will be coming along on Sunday to show my support. I live in Penarth Marina, so I will definitely be going along to cheer folks on.”
“I think it’s a fantastic way to raise money for a good cause.”
The run will be broadcast on BBC One in the Sport Relief Mile Show on Sunday March 25.
