Formed in 2012, ESO Sports owns and delivers the UCI sanctioned Enduro World Series (EWS) - the premier enduro mtb and emtb race series in the world. 


In 2021, ESO acquired the Scottish Enduro Series (SES) to enhance grassroots development and  destination legacy. 

ESO is a part of WB Discovery, Discovery Sport and a partner of Discovery Sport Events and Play Sports Group.
