A Torquay man is cycling from Torquay to London in memory of his mum who died of a heart attack.
Derryn Hill, 28, has done no training before the mammoth ride and set off with only a sleeping bag, £16, and four bottles of water.
He had no prepared route and is using maps on his phone to find his way, sleeping outdoors on grass verges along the way.
Within three days, he had reached Newbury.
Torbay Weekly caught up with him as he was having a rest by the side of a canal.
He said: “I have never done anything like this before. It’s a personal achievement for me and I’m doing it in memory of my mum.
“My legs and bum are killing me but what doesn’t kill me, makes me stronger.
“Everyone thought I wouldn’t make it but I am proving them wrong.”
Christina Hill died of a heart attack four years ago.
Derryn has set up a Just Giving page to raise money for the British Heart Foundation.
For the last three years he was homeless in London after his mum died.
But he has now moved back to Torquay and has found a room in a house share and hopes to find a job on his return.
His bike has already made the journey from London to Torquay, ridden by his friend Nick Hammond.
Derryn then bought the bike off him to do the route back to the capital.
He said: “The bike is in good shape but it’s hard going.
“Before I left, I filled four big bottles of water but people have been giving me more.
“It’s been alright so far but it is very hot and muggy.”
He caught up with a friend in Basingstoke who let him have a shower and something to eat.
He’s not decided yet how to get home, whether back on the bike again, or, more likely, by coach.
A power pack is used to recharge his phone battery but the maps he is using are very draining.
