I’m training to run the London Marathon while carrying a fridge to raise cash for Armed Forces charity

ROYAL Marine Sam Hammond tries to keep his cool as he prepares for running the London Marathon — while carrying a fridge.

The 30-year-old fundraiser, who has dubbed the appliance Fridget Jones, hopes to break the 5hrs 49mins 37sec world record.

He has already set a global best for lugging the 26kg fridge through a half marathon, finishing in Brighton in February in 2hrs and 4mins.

Sam, based at the Culdrose Navy air base in Cornwall, will be running on Sunday with partner Samantha, 28, to raise cash for Armed Forces charity SSAFA.

He said: “Initially I did a race to raise money for Llanberis Mountain Rescue in Snowdonia.

"So I’m used to carrying the fridge for miles at a time.

"It’s the time pressure that’s really going to make this a challenge.

"I hope to come in under the 5½-hour mark.”

He added: ";I am definitely nervous about the physical exhaustion element of the challenge."

"I'm certain that I'll finish the race but I don't know how my body will react in the last six miles or so.

"The furthest I've run before is 20 miles."
