As temperatures reach the nineties, EMSA paramedics remind athletes and spectators to stay hydrated during this weekend's Tulsa Tough bike races.
On Wednesday, they responded to at least five heat-related calls, and they expect more this weekend.
Many local cyclists, like Nancy Karrer, say they've been hydrating all week and training all year for this event.
“In the morning, I get up and drink water very proactively, so I don't come into the race already dehydrated," says Karrer.
She and a group of cyclists met at City Cycles on Thursday to go on a 20-mile ride in the sun to get ready to race in the heat.
“The heat is going to make Tulsa Tough extra tough this year," says Karrer.
EMSA paramedics say they treat people for heat-related illnesses every year at Tulsa Tough.
That's something that Karrer has experienced in the past.
“I've been on a ride and started to get the chills on a 95 degree day, and said oops I did not prepare right," says Karrer.
Organizers of the event are expecting thousands of spectators and athletes to come out Friday through Sunday.
There will be water stations throughout the course, and EMSA paramedics will also be assisting people during the races.
