Built by a coach, for coaches.

Hi, I'm Chelsea!

I spent five years as the head girls cross country coach and assistant distance track coach at a large high school in Indiana. I loved coaching, but what I didn't love was the ever-increasing admin work: endless emails, stacks of forms, event planning, logistical coordination, and everything in between. I had a system, but it meant a lengthy weekly email with plenty of room for error and a million follow-ups every time it got buried in someone's inbox.

Before my third year, I made myself a deal: figure out a better way, or the admin work alone was going to be the death of my coaching career. I didn't know it at the time, but that deal was the beginning of My Assistant Coach.

It started as a live calendar I built in Google Sheets and linked everything into. I launched it that spring and never looked back. The hours spent writing lengthy emails and chasing follow-ups dropped to almost nothing. No more messages asking where the link was, whether the document was current, or what time the meet started. Everything was live, updated the moment I changed it, and accessible to everyone without a login. Word spread. Other coaches at my school started using it, and eventually I presented the concept at the IATCCC Annual Clinic to coaches from across Indiana. The response confirmed what I had suspected: this wasn't just my problem.

The original Google Sheets prototype that started it all.

The spreadsheet had its limits, though. I had to manually change every date each season, events couldn't be moved easily, and I had no way to filter by group or show different views to athletes versus parents. I knew exactly what it needed to become and that's where MAC began to take shape.

MAC is what I wished had existed when I started coaching. I hope it gives you back the hours, and keeps you in the sport for many years to come.

A huge shout out to my assistant coaches for being my biggest supporters over the years. Their commitment to the sport and to our athletes inspired me then and continues to inspire me now. And to my athletes — although I'm sidelined, I am your biggest fan. Always.
