The event will take place in South Wales to mark the 40th anniversary of the Great Daffodil Appeal and will run from 7pm on April 22 until 11am on April 24 at the charity’s Wellbeing and Support Hub.
The hub is located at the Marie Curie Hospice, Cardiff and the Vale, in Penarth.
Participants will cycle in 30-minute slots throughout the 40-hour challenge.
Hannah Warner-Holt, community fundraiser at Marie Curie, said: “We’re excited to bring all our teams together – from nursing to fundraising and everything in between – for this event to mark the 40th anniversary of the Great Daffodil Appeal.
“We’ll have people riding through the night, with the goal of keeping the wheels turning for 40 hours.
“It isn’t a race or spin class – people can go as fast or as slow as they like.
“Thank you to SNAP Fitness for supplying us with the bikes to enable us to do this challenge while raising some vital funds and having some fun at the same time!”
