Guinness World Records confirmed that Max Willcocks is now the new fastest male over 100m. His time of 14.09 seconds was significantly faster than the previous record of 17.65 set in 2015 by German Andre Ortolf.
Emma Kirk-Odunubi ran a time of 16.86 seconds to set the first official time for the fastest female over 100m.
The attempt took place at Barn Elms track in south-west London and both athletes wore Atomic Backland ski boots - light, flexible ski touring boots.
Max was delighted: "I'd skied in the Backland before so I knew the boot, but the only times I had ever run in them before was while running away from lifties when we were night touring!"
Emma was preparing for a marathon at the time: "At the time I was doing some speed endurance and strength training ahead of the Amsterdam Marathon, but I didn't do any specific training for the 100m attempt."
Max doesn't plan to run it again any time soon: "It's seriously hard on the hip flexors. The next time I'm in ski boots, I'll be ski touring!"
