Thousands of children took part in the annual Ironkids event today (Saturday, June 29) as the youngsters took over the town centre.

Despite the damp weather and grey skies, the kids showed up in their thousands, with a record-breaking number of participants in the event.

Organisers said around 5,500 children took part this year in the Bolton race, which is the largest Ironkids event in the world.

The children were split up into 12 age groups, from Year 10 and 11 all the way down to nursery, and starting from oldest to youngest, the age groups set off at different times throughout the day.

Starting at 9am in very wet conditions and continuing throughout the day, children of all ages dashed frantically through the streets of Bolton before crossing the finish line in Victoria Square, where they were rewarded with a medal.

"It's brilliant to see so many kids out doing exercise and having a great time while doing it."

The route was surrounded by people of all ages, from infant siblings to grandparents, who had come out to support the children taking part.

Lisa Miller, 33, who watched her daughter Sarah take part in the Year Three race, said: "It's great fun seeing all the kids running about and taking part in the event.
