It's Ironman time again; this Sunday, thousands of competitors will run, bike and swim through areas of downtown, Riverview and the North Shore.
The competition includes a 2.4-mile swim, a 116-mile bike ride and a 26.3-mile run, for a total of 144.6 miles.
In past years, the event has drawn huge crowds of spectators. The event also means road closures, and some people are organizing alternative or coinciding events.
Here's what you need to know about Sunday.
North Shore cheering party
Here's a list of places to watch the different portions of the race, but a couple of businesses have also teamed up for a cheering party near the event's route.
Brewhaus and Devils Backbone Brewing Co. are hosting a party from 11 a.m. to 8 p.m. in front of the North Shore restaurant, which is located at 224 Frazier Ave.
Virginia-based Devils Backbone Brewing Co. expanded into Chattanooga in 2015 and can be found around town, Kelsey Randall said.
"Who we are as a brand is about craft beer and adventure," she said. "We're about getting outdoors and being active—biking, hiking, all of that is in the brewery's DNA. When thinking about something to do down here, the Ironman really fit with who we are as a brand."
Public activities start Thursday evening with the Ironkids race at 6 on Riverfront Parkway.
The Ironman Expo area will be open on the Chattanooga Green from 9 a.m. to 5 p.m. Thursday through Saturday.
Leaders with the brewery and restaurant also reached out to another local business, Fast Break Athletics, to partner for a drawing at the event. Fast Break will donate some gear and gift cards, Randall said.
The drawing proceeds will benefit Friends of Outdoor Chattanooga and likely help fund their climbing camp scholarships for low-income children, she also said.
