After completing her first marathon, Kate Gosselin deserved a special -- and non-healthy! -- treat.

The 36-year-old mother of eight and former reality star participated in the Zappos.com Rock 'n' Roll Las Vegas Marathon Sunday, which she completed in 4 hours, 59 minutes and 21 seconds.

"For me, Finishing was definitely winning!" the former TLC reality star tweeted Monday. "I could barely walk from finish line. I had to be helped! I never could have done it without my running buddies Paula and Ellen!"

Following the marathon, Gosselin ate "2.5 huge pieces of pizza and some penne pasta and a Coke -- not diet, mind you!"

Gosselin trained for the 26.2 mile run by jogging near her $1.1 million Wernersville, Pennsylvania home.

"Who ever would have thought that I'd be running a marathon?" Gosselin wrote on her official blog Saturday. "Certainly not me, but it's amazing where life leads you if you're willing to live passionately! If I can do this, anyone can!"
