Registration ends this week for the 2019 Fitness Challenge community weight loss competition is open.

The five-player teams that lose the greatest percentage of their starting weights over eight weeks earn the largest shares of prize money to donate to area nonprofit service organizations of their choice. New this year for the 18th annual Fitness Challenge is two divisions — Dynamo if three or more members finished in a top five team in the last five years; Go-Getters if not.

Entry fee is $250 per team, with a $50 nonrefundable deposit due by the Friday registration deadline. The initial weigh-in is Jan. 17 and weigh-ins continues weekly through March 14.

For more information, see the registration form, which will appear daily in the Tribune Chronicle through Friday, or call Tribune Chronicle Community Events Coordinator Sue Shafer at 330-841-1696.
