MRR is operated by Run 4 Wales (R4W), in partnership with ABF The Soldiers’ Charity.

R4W is a not for profit social enterprise and charitable trust set up to promote, manage and deliver major sporting events – whilst supporting and reinvesting in grassroot athletics.

ABF has been involved with R4W for a number of years – across 2018 and 2019 over 150 Soldiers’ Charity fundraisers took part in the Cardiff Half Marathon raising thousands of pounds for the cause, whilst a number of Welsh Guards took part remotely during a tour of Afghanistan – inspiring the MRR movement.
