The 10-mile event, billed as the UK’s biggest night race, was being held at Innerleithen in Tweeddale.
A spokesman for organisers Rat Race Adventure Sports, said: ‘We are extremely saddened to confirm that a participant in our Mighty Deerstalker event passed away yesterday.
‘The participant became unwell at 5.56 pm, approximately one mile into the event, close to our event control station and at the location of one of our safety marshals.
‘A member of our medical team was on the scene within three minutes as we implemented our response protocols.
‘They were assisted by an off-duty paramedic until the arrival of the Scottish Ambulance Service.
‘Tragically, we have since learned that the individual passed away en route to hospital.
Deerstalker is billed by organisers as ‘as tough as it gets’ with competitors running through mud, swamps and across hills

‘Rat Race Adventure Sports will give full assistance to the appropriate authorities.
‘Our heartfelt thoughts and condolences are with the family and friends of the deceased.’
The event, now in its 11th year, sees hundreds of participants tackle off-road terrain while wearing head torches.
On its website, the organisers state: ‘The Mighty Deerstalker is as tough as it gets; hills, mud, swamp, darkness, rivers, obstacles and always devilishly vague on the true distance, this event never disappoints but it often hurts.’
