EC Help!

So I am currently a Sophmore in high school, and I need some advice regarding my ECs. In my Freshman year, I played football, was selected for a tech internship at my school and ran a company I founded in 8th grade. The company is Bulletproof Interactive and I design websites and create software and apps for people. Currently business has been great and I have kinda passed the tipping point to start making real money, and I even have an employee! I have created a revolutionary software that I know I can get many clients from. The problem I am having is sports, I have been planning to play track this year, but am afraid of wasting valuable time that could be put towards my company. I have been training and currently, am running long distance times that will take me to state. Do you guys think that it would be detrimental to my college application if I don’t do track and just focus on my company? This would literally be the only EC I would have for this year, but it takes about 15-25 hours a week of my time. My aspirations are to go to Stanford or MIT and don’t want to screw up because I just had one EC. Thanks!
