Chubb won the Class AAAA shot put Thursday afternoon on his final throw of 55 feet.
"It shows I'm truly balanced," said Chubb, who graduates from Cedartown High School on June 1 and will report to Athens the next day. "I can do it all. I'm an athlete. I can run and I can throw. …I'm truly blessed. I worked very hard to get this."
The 5-foot-11, 226-pound Chubb will show off his motor Friday after qualifying in the 100 and 200-meter dashes and the 4x100 meter relay.
"I'm planning to medal, place in everything I do--top three in everything hopefully," he said.
He ran a 10.69 in the sectionals in the 100 and is second-seeded.
Chubb is part of a 1-2 tailback punch the Bulldogs signed along with Florida five-star Sony Michel.
Chubb rushed for 2,690 yards and 41 touchdowns as a senior last fall and set a GACA state power clean record with a lift of 395 pounds this winter.
"I didn't really felt like I won anything because I do that stuff every day," Chubb said. "It's better competition out here."
After Chubb's final throw put him ahead and he ended up winning, Cedartown track coach Mike Worthington joked with him: "What are you trying to do give me a heart attack?"
Worthington is pointing Chubb towards shot put and 100-meter titles.
He wants Chubb to match former Cincinnati Bengal running back Larry Kinnebrew from East Rome who won state titles in the 100-yard dash and shot put in the late 1970s.
After his shot put win, Chubb said: "I really don't know the feeling. I've never had this feeling before. I never won anything, but it feels good to be a champion finally. I look forward to more championships."
Chubb qualified in the long jump last year, but figured he had a better chance to win at shot put.
Reese Hoffa, the former Georgia thrower who won the 2012 Olympic bronze medal winner in the shot put and who still trains in Athens, was watching the AAA competition because his wife is the throws coach at Oconee County.
"It doesn't surprise me," Hoffa said of Chubb's prowess in the shot put and sprints. "Being just a great athlete, you're going to be able to do things incredible and I guess throwing the shot put and sprinting is no different."
Chubb woudn't mind putting on a few more pounds before August practices.
"As long as I keep my speed," he said.
Even in a crowded backfield, Chubb will enter his freshman season trying to earn his spot.
"I'm self-driven," he said. "I'm motivated. I'm ready."
