People across Bucks are being invited to take part in a 'parkrun for the NHS' this morning to mark its 75th anniversary.
Staff and volunteers are encouraged to dress up for the 5-kilometre event - an opportunity for local communities to acknowledge its contribution.
A similar event held to mark the service's 70th birthday in 2018 saw a turn-out of 146 thousand runners.
