The Great Harwood 10k was cancelled this weekend after temperatures plummeted below freezing and the borough was coated in several inches of snow.
The annual charity race, in aid of East Lancashire Hospice, had to be rescheduled as organisers feared for the safety of runners, with up to four inches of snow having fallen in some parts of Hyndburn.
The weather may have been a nightmare for many, but children turned out en masse to build snowmen and sledge.
Huncoat weatherman Roy Cheetham said: "There was an intense snow shower in the early hours of Saturday morning which continued on and off until the evening.
"The snowfall is very varied across the region because of the height difference between the low lying areas and the hills.
"In Hyndburn it has generally been around two inches on the ground, but on the hills you could get around four inches."
Lancashire County Council, which is responsible for gritting highways, said that gritting had been carried out as planned.
County Councillor John Fillis, cabinet member for highways and transport, said: "We've made detailed preparations for wintry weather which focus on keeping traffic moving by concentrating gritting on the main routes. We're as ready as we can be for any prolonged severe weather.
"I'd ask everyone to be very careful as moving traffic is needed to mix the grit with the snow and ice before it takes full effect, and roads may still be icy even after they've been gritted depending on the conditions."
Temperatures fell to minus two in parts of the borough, with thermometers plunging as low as -12.5C in some parts of the country.
Forecasters warn the cold temperatures, below the seasonal average, could continue until later in the week, with snow likely in the East Lancashire region tomorrow and Wednesday.
The Met Office has issued an amber warning - the second highest - for icy conditions across most of England until midday on Thursday.
An alert on its website said: "Large areas of England will experience colder than average conditions in the coming week, with widespread overnight frosts. Some wintry precipitation is expected for most areas too, mostly in the form of scattered showers, leading to lying snow and icy stretches."
The date for the Great Harwood 10k has been revised to Sunday, January 25.
The venue for the start at Gaskell Motor Bodies remains unchanged but registration will open at 9.30am and the run will start at 11am.
Louise Gaskell, one of the run's organisers, said: "We were really disappointed the run could not go ahead. Everyone had put so much work into it, but safety is the most important thing.
"We managed to contact the majority of the runners in time, with only 20 out of 330 still turning up."
