Gwen Jorgensen sprays champagne to celebrate her victory at the World Triathlon Grand Final London at Hyde Park as part of the ITU World Championships Series on May 31, 2014 in London.

 

Gwen Jorgensen is an Olympic gold medalist, and now she’s a mom, too.

Jorgensen, who became Team USA’s first Olympic triathlon champion last year in Rio, announced the birth of her son on Twitter on Wednesday with the message, “Such a rewarding day! I'm a bit too tired to post photos so you will have to wait to see all the cuteness. Our hearts are full of joy.”

Stanley Allen Lemieux was born to Jorgensen and husband Pat Lemieux on Wednesday weighing 7 pounds, 10 ounces and measuring 21 1/4 inches. Mom and baby are doing well, according to Jorgensen’s Twitter.

On Monday, Lemieux posted a picture of Jorgensen eating spicy food saying they were trying to send the baby into “launch mode,” which Jorgensen retweeted saying, “11 days past ‘due date,’ baby really likes my belly."

Jorgensen, a former runner and swimmer at Wisconsin, has taken the triathlon world by storm in recent years. Since making her Olympic debut in London in 2012, where she finished 38th while sustaining a flat tire on the bike, Jorgensen has used her blistering running speed to dominate the World Triathlon Series, including winning the Grand Final in 2014 and 2015.

In Rio, Jorgensen won the women’s triathlon nearly a year ago to the day, with a time of 1:56:16.

Jorgensen, 31, and Lemieux announced they were expecting their first child in January.

Although she took this competition season off, Jorgensen continued to work out and told NBC in an interview at 28 weeks pregnant that she had three weeks where she was running 100 miles per week. She plans to return to competition in 2018 and go for a second consecutive Olympic triathlon title in 2020.
