Crowds of children will gather around Leicester's Clock Tower on Tuesday morning to begin the city's countdown to the start of the Commonwealth Games.
The gathering will be part of a day of events welcoming the arrival of the Queen's Baton Relay.
Claire Lomas – who completed the London Marathon in a robotic suit in 2012 after breaking her back in a riding accident – is due to join the youngsters at 11am.
She said: "It's a real honour to welcome the Queen's Baton to Leicester and be part of a celebration of our great local athletes, clubs and sports volunteers ahead of the Commonwealth Games."
Six baton-bearers, chosen for their contributions to sport and the community, will carry the baton at events on the Leicester leg of its journey.
They are Paige Murray, Cherie D'silva, Mike Smith, Ross Davenport, Trevor Low and Shiv Thakor.
Shiv, who plays professional cricket for the county, said: "I'm extremely proud to play for Leicestershire, and I'm very proud to say that I'm from Leicester.
"I hope that people turn out in numbers on Tuesday to welcome the baton to Leicester and show the world we're getting behind the Commonwealth Games."
About 300 children will get involved in sporting activities in Abbey Park while people of all ages will join in the celebrations in Town Hall Square from 5pm.
Live music and dancing – with a Commonwealth theme – will continue there until 8pm, with plenty of opportunities for people to have a go at a new sport.
Assistant city mayor councillor Piara Singh Clair said: "I'm delighted that Leicester has been selected to host the Queen's Baton Relay.
"This is a great opportunity for our city to show its support for Team England – and encourage local people to get active and involved in sport."
Dame Kelly Holmes, President of Commonwealth Games England, said: "I'm encouraging everyone in Leicester to get involved when the Queen's Baton Relay comes to your city.
"Find out what event is taking place and if you can be there then please go and cheer on your baton-bearers and be part of the Team England send-off to Glasgow."
