Levi Lukacs, a Hungarian-born professional triathlete now living in St. Louis, is going the distance for Pedal the Cause. 

On July 15, the 28-year-old will attempt to set a Guinness World Record for the longest single-day triathlon by swimming 7 miles, biking 186 miles, and running 47 miles. In total, Lukacs plans to cover 240 miles in 24 hours; the current record is 226 miles. 

Lukacs is attempting the record to raise awareness and funds for Pedal the Cause, a nonprofit cycling and community event that uses 100 percent of public donations to support cancer research at Siteman Cancer Center and Siteman Kids at St. Louis Children’s Hospital.

“Cancer has personally affected my life because, when I was younger, my mom fought through breast cancer. Luckily she won, but that’s not always the case for many people,” Lukacs wrote on his Pedal the Cause profile page. “I chose to fundraise for Pedal the Cause with my challenge, so we can be one step [closer] towards finding a cure for cancer.”

The public is invited to join Lukacs as he starts the run portion of his world record attempt. The run is anticipated to begin around 5:30 p.m. on July 15, leaving from the Swim Bike Run store at 14830 Clayton Road in Chesterfield, Missouri. Learn more at facebook.com/events/885651486028903.
