“Times have changed tremendously in the Bronx, the Bronx is now… you know before, you got to the Bronx and if people were running, obviously they were running not for a good reason, now you look anywhere around the Bronx, and people are running everywhere, right? People are so comfortable in their own skin to get up and go outside and run in the Bronx now, right? You know, Boogie Down Bronx Runners, it’s identity created something that kinda like, pushed the needle a little bit, you know? on the positive side of changing the stereotypes of what people expect out of the Bronx.”
In this episode of Beyond Running, host Mau Diaz sits down with Lenin Grullon, co-founder of Boogie Down Bronx Runners, to talk about almost ten years of building one of NYC’s most respected community running crews.
They talk about what it actually took to build a running club from scratch, how Lenin’s “community first” philosophy shaped every decision along the way, and the challenges of staying true to that mission as the club grew from a handful of runners into a full-blown family. Lenin opens up about the early mornings, the doubts, and the moments that made it clear this was bigger than just running.
The conversation also crosses borders. Mau and Lenin dig into the story of when Lenin brought Boogie Down Bronx Runners to Oaxaca to experience Aire Libre in person, and what it meant for two running communities from completely different worlds to connect through the same love of the sport. It’s a reminder that running has a way of building bridges, no matter where you’re from.
Lenin “Lenny” Grullon is a Bronx-based educator, community leader, running coach, and advocate who uses movement to advance health, inclusion, and community empowerment. He is co-founder of Boogie Down Bronx Runners, a grassroots organization established in 2017 to foster wellness, connection, and Bronx pride through running.
Lenny serves as a Physical Education teacher at DREAM Charter School, where he focuses on physical wellness, youth development, mentorship, and building confidence in young people. He has also served as a Nike NYC Running Coach, bringing community-centered leadership to running experiences across New York City.
His commitment to inclusive athletics extends to Fast Feet NYC, where he serves as a Board Member and has worked as a Lead Coach in its Adaptive Running Program, supporting young athletes with disabilities. Across education, athletics, and community service, Lenny is dedicated to strengthening communities and creating meaningful opportunities for people of all abilities and backgrounds.
