Big Brothers Big Sisters of Northwestern Michigan


Listen to Chris and Tony talk about Tri4Kids on the Michigan Runner Girl podcast!

My name is Chris Girrbach and I’m a local business owner in Traverse City. I have embarked on a 15-20 year journey to help raise awareness and funding for Big Brothers Big Sisters (Bigs). I am going to participate in 50 triathlons or duathlons in 50 states and my plan is to complete 3-4 per year. My first official triathlon was in 2020 and I have conquered 6 more since with my next 2 Triathlons coming up in May of 2024!

I’ve learned a lot about Bigs over the past several years, and the many challenges and heartaches the children in this program face.  I wanted to do my part to help Bigs the best way I know how.  Some kids get the short end of the stick, and Bigs makes a world of difference to those kids, so it’s the least I can do.

I hope you will support me be pledging a dollar amount for each Triathlon I complete. Click here for more details.

I was inspired by Tony Anderson, who ran 51 marathons in 50 states to support Bigs.  Tony completed his last marathon in May, 2020.  

I realize this is a 15-20 year commitment and I’m up for the challenge…LEARN MORE ABOUT CHRIS
