Michal Kapral

[1] In September 2005, he joggled his first marathon as a charity stunt for Toronto's SickKids Hospital, initially planning to do it just the one time.

[6] He wound up setting the marathon joggling record with a time of 3:07:41, thirteen minutes faster than the previous mark, leading him to pursue the sport further.

[12] In 2014, Kapral set the world record for fastest joggling half-marathon at the Toronto Waterfront Marathon, with a time of 1:20:40, dropping just one ball.

[6][13] At the 2015 New York City Marathon, organizers prevented Kapral from joggling by deeming beanbags a prohibited item for security reasons.

[16] In October 2016, Kapral ran the Chicago Marathon while juggling, managing to do so without dropping any balls, and finishing with a time of 2 hours and 55 minutes.
