Technical issues forced PantherFest to cancel their first wave of Slide the City Saturday morning.
The event was scheduled to kick off at 10 a.m. with participants riding a 2,000 foot slip-n-slide down North Main Street.
Organizers spent the morning working on the slide while attendees waited it out. As a result, ten people had to be treated for heat-related illnesses.
Fort Worth Police and Fire Department's also responded to help cool crowds, including a downpour from a fire truck.
MedStar deployed their AMBUS to help treat the patients. No major issues were reported but officials continued to remind all attendees to stay hydrated and take shade if needed.
After a six hour delay and a few hiccups, the slide was up and running for participants to enjoy and attempt to break a World Record for the longest distance traveled on a slip and slide in one hour (from 5:30-6:30 p.m.).
A Guinness Book of World Records spokesman at the event proclaimed that Slide the City obliterated the world record in the first hour in just one lane. More than five times the previous record of 2,540,061 ft.
