Hi, Michele. Yes, you can participate in another HealthyWager (our individual weight loss challenge completely customized to you with a huge cash prize up to $10,00!), after you complete your first! In fact, many participants like to break up their weight loss goal into a few HealthyWager challenges and have found it effective and motivating for both weight loss and maintaining it. Do know that if you win a HealthyWager and start a new one, your starting weight will be your winning weight from your last HealthyWager win.
