About
On Saturday, 9 May 2026 at 12:00, the Dublin Mountain Backyard Ultra—better known as Barry & John’s Dublin Mountain Backyard Ultra—takes place in the Dublin Mountains around Ballinascorney/Glencullen, Co. Dublin, Ireland, organised by the Dublin Mountain Running Club. Run in classic backyard format, athletes have one hour to complete each 6.706 km trail loop on repeat until only one runner remains “last one standing,” making this the official Leinster Backyard Ultra qualifier for the All-Ireland BYU Championship.
