Thin Mint Sprint is Virtual ...

Throughout September!


TMS 2020 is virtual! Due to ongoing COVID-19 health and safety concerns, GSNI’s Board of Directors has decided to cancel the in-person Thin Mint Sprint event at Harlem High School. While this is disappointing, the good news is everyone can still participate in Thin Mint Sprint fun virtually! We’ve added an 8K Virtual Race (for those who want a challenge!). To participate virtually, simply choose your course and complete the race or walk anytime in September. A virtual leader board will track everyone’s time! Event T-shirts will be available when you register. You can even print out your own bib number! So gather your family or some friends and join us! Find details and register for each event at

Lace up those running shoes! Could you be faster than Fiona? GSNI’s CEO, Fiona Cummings, has a ton of energy, and she’s always up for a challenge!

Girl Scouts register for $15.
