A teacher is aiming to complete his seventh marathon in as many days later today.

Lee Perry from St John’s School in Bury Lane, Epping, embarked on the remarkable feat at the start of the week to honour his father who died from a heart attack while out running 20 years ago.

The 26-year-old maths teacher is also hoping to raise awareness and around £2,000 for the British Heart Foundation.

He said: “I’ve never done something this extreme but I wanted it to be a challenge both physically and mentally.

“I’ve found myself shouting at myself while running to get me through the run at some points.”

The former Davenant High School pupil from Ware has had to get up at 4.30am in order to get to work on time and has lost a stone and a half since starting.

He runs a half marathon on the way to school and another on his return home.

He said: “I’m relying on adrenaline and the prospect of a Domino’s pizza and a few beers tonight to get me through my final run.

“The support from the head and the rest of the staff has been fantastic too.”

Headteacher at the school, George Yerosimou, said: “We are all in disbelief.

“Just one is a feat in itself and requires dedication.

“I was humbled by his determination to do this.”

Mr Perry’s sister Gemma, who also works at the school, completed a half marathon of her own on Sunday.
