Beckie Holt likes nothing better than curling up on the sofa in front of the fire at home and reading a good book.
However, all that has changed.
For the next 125 days, the Horncastle based police officer will be running a minimum of two miles every day.
In total, she will be clocking up 250 miles - almost the equivalent of a return journey to London.
Beckie is taking part in a daunting challenge to raise funds in memory of PC Nicola Hughes, one of two police officers who were gunned down in Manchester in September 2012.
PC Hughes’ father, Bryn, will be running the North Pole Marathon next April - a 26-mile route across the frozen Arctic Ocean.
Beckie has stopped short of that particular challenge but is already tackling her own ‘marathon mission.’
She completed her first two miles last Sunday (December 1) and hopes to cross the finish line in early April.
Beckie said: “Everyone was upset by what happened to the two officers.
“It could have been any one of us.
“I wanted to do something to raise money and I thought this was a good idea.
“The only trouble is I’m not really a keen runner. I prefer being tucked up at home with a good book - especially at this time of year.
“However, I’ll be out in all weather - rain, sleet and snow.”
The 125-day challenge will raise money for three causes - COPS, which cares for members of police officers killed on duty, the Police Benevolent Fund and Victim Support.
Beckie has received plenty of encouragement from fellow officers at Horncastle - and her young daughter.
