It's to demonstrate the effects and dangers of sleeping rough.
A huge, mass sleep-out is being held at The Piece Hall in Halifax on Wednesday night.
Nicky Chance-Thompson, the chief executive of The Piece Hall Trust, is among those joining charity Happy Days at the Grade I listed building. Happy Days have cycled 350 miles this week in a bid to raise ten thousand pounds for the homeless.
Commenting on the ride, Dave Fawcett, CEO of Happy Days commented "We set up Happy Days in 2014, and since then have gone on to help a huge amount of people find a home, and even get back in to the workforce."
"Everybody taking part in this ride has a huge love and passion to change lives and improve local communities. Whether it's raising money, volunteering or just changing attitudes towards homelessness, I hope we inspire as many people as possible over the coming days. Anybody can be a victim of bad circumstances, but it can be so simple and easy to make a difference in someone's life who needs it the most."
On the final night, January 31st, the Happy Days team have extended an open invitation for those wishing to raise money themselves. The iconic Piece Hall in Halifax will hold a mass sleep out to demonstrate the effects and dangers of sleeping rough.
Chief executive Nicky Chance-Thompson added: "I'm delighted that The Piece Hall is hosting the Happy Days group on the final night of their ride from London to Leeds. Homelessness is not only a huge national issue but a local one too, and The Piece Hall Trust is very pleased to help raise awareness of this issue, and to support such a great local homelessness and addiction charity."
