More than £4,500 was raised for the Niamh’s Next Step appeal at two fundraising events.
The appeal was set up with the aim of raising £450,000 for five-year-old Niamh Curry from Wellingborough to go abroad for treatment for neuroblastoma.
Teachers, governors and parents from Niamh’s school, Little Harrowden Primary School, trekked around Grafham Water in Cambridgeshire in the middle of the night on Friday night to help raise money.
Niamh went into school on Friday, when the children also took part in a mufti day for the appeal, to wish everyone taking part in the midnight walk good luck.
The event had raised more than £2,800 before participants even set off on the walk.
It took them just over three hours to complete and donations have now reached £4,240.
The school’s business manager Kate Pettifer said everyone who had taken part in the walk had got into the spirit of the occasion.
She said: “It was absolutely brilliant, we had 115 people walking and we all did it in just under three hours.
“There was a lovely feel to the evening, I think everyone really enjoyed themselves.
“We started walking just before midnight and the last people arrived back at 3.05am.
“We had teaching staff plus the chair of governors and other governors, parents, grandparents and some volunteers from the St John Ambulance.
“Everyone raced round, I think everyone surprised themselves by how quickly they finished it.
“It was a really super evening and we are really happy to raise lots and lots of money for Niamh.”
Avant Garde in High Street, Wellingborough, also did its part for the appeal by holding a dress down day on Friday. The salon’s event has raised about £500 so far.
