You don't need a participation medal in taking care of yourself. Right now you aren't earning more money or being directly rewarded by being healthy but this is a personal investment in your own future, why should anyone else show any form of recognition to a very personal life choice?

I do the same, I'm healthy, I go to the gym, I bike to work, my reward is getting older fit while I see people on my age group having more and more issues.

Yup, you might be more productive than someone that is unhealthy and taking sick days, etc., at the same time you don't use your paid time off (or have days discounted from your salary, such as here in Sweden) for when you got sick.
