An initiative to encourage youngsters to become fit and active was launched in Morpeth.
Northumberland Athletics Network, along with Active Northumberland and Blyth Valley Arts and Leisure, hosted the first Go Run for Fun.
The national campaign is set to go nationwide with the aim to inspire children aged five and over to be active, promote health awareness and help maintain children’s enthusiasm for sport following the London 2012 Olympics.
Emphasis will also be placed on supporting existing and new children’s running events.
A 1.5km fun run course was laid out at Chantry Middle School, in Morpeth, for the first event, with more than 100 children taking part.
Each youngster received a free pink T-shirt and race number, with international athlete John Mayock starting the event at 6.30pm.
Northumberland Athletics Network (NAN) officer Hemant Desai was praised for setting up the event, with organisers looking forward to returning to Morpeth for future events following the success of the pilot launch.
A spokesman said: “NAN should be very proud of being the first in the UK to host the GRFF event.”
