Many people are hoping for a cool down by the weekend, especially those competing in the Ironman 70.3 this Sunday.
The Ironman 70.3 is set to kick off this Sunday in Chattanooga with nearly 3,000 athletes participating in the competition.
Officials say visitors will see several road closures as crews work to set up the race. Crews started setting up on Monday.
"This is what we call the build out time to prepare for Sunday's activities," said Tim Morgan, President of Chattanooga Sports Committee. " Our community has really become kind of a well oiled machine when it comes to hosting Ironman events."
The race will start at Ross's landing with 1.2 mile swim in the Tennessee River, followed by a 56 mile bike ride through downtown Chattanooga and parts of North Georgia.
Officials say the last leg includes a 13.1 mile run on the Riverwalk and North Shore, where spectators will have the best views.
