Three candidates so far are vying to replace Fort Worth Mayor Mike Moncrief, who announced last week that he would not seek re-election.
Monday was the first day candidates could file for City Council and mayoral races across North Texas. The last day to file is March 14.
Former Councilwoman Cathy Hirt turned in her paperwork Monday afternoon, saying she's ready to take on the issues before City Hall.
"It's not just that I'm up for the challenge, but I think the citizens of Fort Worth are up for the challenge," she said minutes after filing.
Hirt decided to run months ago and already has a website, Twitter account and Facebook page.
"Our campaign video is up; our headquarters are ready to go; we have a good 300 volunteers ready to go," Hirt said. "Yes, of course, I think I have an advantage."
"For me, it's never been about the politics, it's been about the service," Price said.
She said close friends encouraged her to run, and said she doesn't think her late entry will be a problem.
"I've been in campaigns for 10 -- this is my 11th year -- and you just get organized and get after it," Price said.
"Our city's past and future are both very important to me, and that is why I am running for mayor," Lane said in a statement.
All three candidates said that dealing with the budget will be the biggest issue.
Election Day is May 14.
