P.E.I. curler Kim Dolan, who just completed her 12th trip to the Scotties Tournament of Hearts championship, is retiring from competitive curling.

Dolan has been a powerhouse in women's curling for nearly three decades, and she says it is time for a rest. She announced her retirement in a video posted on the Canadian Curling Association website.

She said it was good to finish with a win over New Brunswick in her final match on Thursday in Red Deer, Alberta.

"It's a great way to go out. It would have been nice to have a few more through the week," said Dolan.

"Great games, and you know my team played well and all that, so it's a great way to finish."

Dolan's competitive career includes nine PEI provincial championships. She first appeared at the Tournament of Hearts in 1983 and has been there 12 times as a player, coach and alternate.

This year was special for Dolan in two ways. She won the provincial championship as a skip for the first time in 13 years, and played alongside her daughter Sinead.
