Francis completed the Centurion 2018 Grand Slam, four 100 mile ultramarathons in five months in an aggregate time of under 100 hours. The Slam consists of Thames Path (Richmond to Oxford), South Downs Way, North Downs Way and Autumn 100 (two 25 mile spurs each of The Ridgeway and Thames Path.) In 2019, he takes on Hardmoors 110, a 112 mile race along the Cleveland Way, taking in the North York Moors and hopes to land a coveted entry to The Tooting Bec 24-Hour Self-Transcendence Race, whose goal is to run as many laps of the track as possible within the time.
