A devoted daughter pedalled the length of the Leeds-Liverpool canal to raise £5,000 in memory of her father who died from motor neurone disease.
Corinth Blackwell cycled the equivalent of five marathons in 48 hours as she rode the 127-mile length of northern England's largest canal.
It is the second challenge Mrs Blackwell has completed since her father, Richard Dutton, 57, from Ellesmere Port, passed away from the disease in January 2013.
Motor neurone disease is a degenerative condition for which there is no cure and only limited treatment. It causes the death of neurones that send messages from our brains to our muscles; once the neurones die, the muscles waste away, and with them the ability to move, speak, swallow and breathe.
The 27-year-old geography teacher has now raised more than £5,000 for the Motor Neurone Disease Association, the only national charity providing help and support for those living with MND.
Mrs Blackwell was joined by her husband Richard, 28, and friend James Drury Payne, 31,who came together to tackle the mammoth waterway in a single weekend.
Setting off from Canning Dock in Liverpool on the evening of Friday, August 23 the trio cycled through all 91 locks finishing in Armley, Leeds on Sunday, August 25.
Mrs Blackwell said: "It was a really tough challenge. Not only is the canal a long way, but the terrain also makes it very difficult – one moment you're on the tow path and the next moment you're cycling on wet grass, which made it very slippy."
Mr Dutton, who worked as a metallurgist for more than 20 years at the Ford plant in Halewood, was diagnosed with MND in November 2010. As well as being a huge fan of Liverpool FC he was an enthusiastic poker player.
The first challenge Mrs Blackwell completed for MND was a 19 mile sprint triathlon, which raised more than £2,000.
The teacher at Archbishop Temple School in Preston said: ""It was a bit of a shock to us that he passed away so soon. I wish he was still here, but it's so horrible to watch someone you love living with MND.
"I had heard of MND before my Dad was diagnosed but I didn't have a clue what it was. Then when you read about it on the internet it scares the life out of you.
"When my dad was diagnosed he didn't want to talk about it too much. His attitude was that he wanted to live the life he's got to the full."
Corinth is considering cycling from London to Paris for her next challenge.
