Information:

I'm a 21-year-old male who is reasonably healthy, will be doing this in NYC. I did cross country in high school, and have an average steps/day of roughly 10k, maximum of 35k, and I've never tried to take as many as I can in a day.

Sometime in the next few weeks, on probably a Saturday, I'm going to try to take as many steps as I can in one day (12:00 AM to 12:00 AM, 24-hour period, measured by my Apple Watch). I've made some bets with people on how many I will take, so I have pretty good motivation - currently I will break even around 60k steps, and earn something like $0.03 per step after that.

This market settles to the number of steps I take on the day I try to do this. Settles N/A if I never make an attempt at it due to injury or something else (though I think this is unlikely). Feel free to ask any other clarifying questions.
