A sponsored walk aiming to raise £100,000 for The Big Issue has been called off because of the extreme weather.
The walk, planned for Friday night in London, was the biggest fund raising event for the Big Issue Foundation.
The charity is now calling on supporters to sign-up to a virtual fundraising event, The Big Step Challenge, to support Big Issue vendors to take positive steps away from the streets.
People can take part anywhere in the country by using a phone or computer to reach a 10,000 step target on a day between March 12-25.
Stephen Robertson, chief executive of The Big Issue Foundation, said: "It is with deep regret that we took the decision to cancel The Big Night Walk due to severe weather conditions.
"Our work continues regardless and I am hopeful that participants will continue to fundraise, despite the cancellation, in the knowledge that every penny raised is vital in our support work and the journey of change we try so hard to create for Big Issue vendors."
