Created in 2022 by the chief executive of Brentwood BC and Rochford DC, Jonathan Stephenson, the Public Sector Challenge rallies public sector individuals, teams, and organisations to raise money for Cancer Research UK by climbing three selected peaks in the UK, in 24 hours. 

In 2023, Jonathan teamed up with 150 sector employees and partners, alongside The MJ, Solace, the LGA and Socitm to climb the three highest peaks in Scotland, England and Wales within 24 hours and raised £60,000 for Cancer Research UK.
