Longtime Iditarod musher DeeDee Jonrowe, 63, took to social media Sunday to announce her final race in the Iditarod.

Jonrowe teased ahead of her big announcement Sunday morning writing, "Keep up with my Instagram and Twitter to find out the news!"

Four hours later, she posted 2018 will be her final race. In her update she thanked her fans:

"Thank you to everyone who have been there over the years!"

This will be Jonrowe's 36th Iditarod start. Though she has never won the race, she has 16 top 10 finishes, and is as big an Iditarod icon as any champion.

Despite some struggles in life -- being diagnosed with breast cancer in 2002, losing everything she owned in the Sockeye Fire and losing her mother to breast cancer five weeks after that -- Jonrowe has pulled through each of those challenges.

"I have had many successes and disappointments in the past 30+ years but one element has remained consistent. I have always tried to do my very best and I have always enjoyed the special bond and love that I have shared with my dogs," Jonrowe wrote on her website. "It has been my privilege to share this unique experience with the volunteers and race fans.”
