This is the heartwarming moment a schoolboy with Down's Syndrome came first in a sports day race - after a group of his classmates teamed up to let him win.

Pupils at Baydon St. Nicholas Primary joined arms and ran one step behind 11-year-old Ollie Chambers until he crossed the finish line.

A clip filmed by Ollie's proud mother, Helen, shows her son glancing at his Year Six friends in disbelief as he sprints as quickly as he can.

Spurred on by cheers from the crowd, he races to the end of the track and is congratulated by his classmates at the school near near Marlborough in Wiltshire.

This is the heartwarming moment Ollie Chambers, who has Down's Syndrome, won a Sports Day running race after his schoolmates joined arms to support him to the line

Ollie's mother Helen said the surprise act by his friends left her and husband Richard, a 37-year-old builder, in tears.

Mother-of-four Helen, 44, of Lambourn Woodlands, Berkshire, said: 'I didn't know anything about it on the day and most of the teachers didn't either.

'It was the Year Sixes that came up with the idea. They planned it themselves and asked their teacher at the start if they could do it.

'Ollie takes part in all the races every year and every year he comes last. It was the final race in year six. Every year they have that race and usually it is very competitive.

'For them to give up the chance to win and let Oliver win was such amazing thing for them to do.

'His face was great when he crossed the line - he was really chuffed and he got a first place sticker which he was very proud of.

'He had no clue at all. He was pretty overwhelmed by it and I was taken aback. I couldn't believe it.

'The tears came and we were just clapping and cheering - it was very emotional. After the race the headmaster came up to me and he was very emotional too.'

Ollie's parents were completely unaware of the children's plans and couldn't believe it when the race began

His mother, whose other children are nine, six, and three, added: 'When I took him to school the next day they treated him like a hero.

'It just shows you in this day and age how things have changed and how children will accept other children with special needs.

'For them to give up that race just means so much. I take my hat off to the boys for doing it.'

Kirsty Liddiard, a teaching assistant at Baydon St. Nicholas who works with Ollie one to one, said there wasn't a dry eye on the field.

She said: 'I knew about it in advance - they let me know about it two months before the sports day.

'It was the whole group of year sixes who decided that as it was Ollie's last sports day it would be good to him to win something.

'They asked me and I said, 'It is your choice.' But they wanted to do something for him - something he would remember.

'There wasn't a dry eye on the school paddock field and there were a lot of surprised faces. We were all so proud.'

It comes after Year Six boys from Wrawby St Mary's C of E Primary School near Scunthorpe in Lincolnshire and pupils at St Oswalds Catholic Primary School, in Ashton-in-Makerfield, Wigan did similar things for schoolmates with Down's and cerebral palsy at their schools.
