Orkney-based ultra marathon runner, William Sichel (63) shows no sign of slowing down as he has launched an unprecedented goal of setting a total of 750 ultra running records, in the coming years, in a project he is calling “Journey to 750”.

This follows on from Project 60@60 (60 records) which he completed in November 2012 and Project165 (165 records) which he achieved in November 2015.
