It was more like a scene out of a horror movie rather than one of the region's most picturesque settings.
But runners taking part in this event with a difference at Hockwold Hall, near Thetford, kept their cool in scary circumstances.
Zombie Evacuation Race was founded in the UK in 2012 and since then has since seen thousands of competitors take part with races all over the UK.
People can sign up as either an evacuee - a runner - or one of the chasing zombies, with both having navigate top secret obstacles along the 5km course.
Racers also encounter dark abandoned buildings, belching smoke and 'corpses' in a zombie hospital along the way, as well as 'minefields' to get through and zombies often camouflage themselves, hiding in bushes then leaping out unexpectedly to ambush racers.
Aaron Murrell, UK race director of the Zombie Evacuation Race series, said around 350 runners took part, with 60 people dressing up as zombies.
'Our race motto is 'Only the fittest will survive' and Zombie Evacuation Races are not for the faint-hearted,' he said.
'The thrill of dressing up as a zombie in full make-up, or else being chased by one, makes some people scream with excitement.
'It's the thrill of the event - when you go round you never know what's around the corner.
'We had some great feedback and saw a real mix of runners.'
The organisers of the Zombie Evacuation Race plan to bring it back to Hockwold Hall next year.
