Kieran is a world record-setting runner and one of the UK's most experienced running journalists.
A constant tester of the latest fitness technology, he's always hunting for innovations that can make him run faster, further and generally be in better shape.
Kieran is often found wearing four GPS running watches at once. And to date he's tracked more than 50 marathons, 13 ultras and countless half marathons - including the Marathon Des Sables.
In 2022, he became the first person to run the river Danube from sea to source, a measly 1,830 miles in 66 days. And still had time to test running gear.
Kieran regularly takes running tech to the extremes for Wareable and the likes of Runner's World, Mens Health and Wired.
