VR game to help people exercise

So one of the big barriers to an overweight or inactive person going out and doing a bunch of exercise is that they suck at it and would be in the public eye. So imagine there’s a VR game where in the headset you are at the starting line of a race in a packed stadium. You can hear a crowd, they’re cheering your name, and no matter if you walk or run, you win this race. And they get addicted to the support and screaming fans and they keep coming back for more. The one place they can be a sporting hero.
