It started as Sinfield’s December ultra-runs usually do, in gusts and slicing rain, from the Suffolk market town of Bury St Edmunds to Ipswich Town’s Portman Road 42km (26 miles) away. From there over seven days it shifted over the Irish sea, then to Swansea, up to Sheffield, across to Workington and Whitehaven, over the Scottish border to Carnoustie and Dundee, then back south towards Headingley, where Sinfield played rugby league with the late Rob Burrow, who died last year with MND.
