This record is for the greatest distance a person can 50-50 grind on a rail.
This is to be attempted by an individual.
This record is measured in kilometres to the nearest 0.001 km, with the equivalent imperial measurement also given in miles.
For the purposes of this record, a 50/50 grind is defined as sliding on the axles of the trucks of the skateboard. Note that ‘board slides’ (i.e. sliding on the underside of the deck) are a separate category of record.
