Woody Felton, 52, was diagnosed with autism last year - something he said just ‘made sense’ to him.
Woody ran 428 miles from west to east to raise money for the National Autistic Society.
“It went really good - I was the first person to ever do it - it feels good to say that,” he said.
Woody joined the army after leaving school and said finding out he was autistic changed his perspective on life.
His son was also diagnosed in 2020 whilst his daughter is also going through the same processes.
He set out to raise £2,000 but has now raised more than double that - with a total currently standing over £4,300.
