Overview

The Butterfly 5K is one of those races that hits you a little differently before you even get to the start line. It’s run in memory of Daniela Marie Conte, an 8-year-old who spent four years fighting a rare pediatric cancer called Rhabdomyosarcoma before passing away in March 2020. The Daniela Conte Foundation she left behind raises money for families of children with cancer and funds research to help kids fighting the disease. This race is the foundation’s flagship event, and the energy reflects that.

Heckscher State Park is a genuinely nice place to run. The USATF certified 5K loop uses the park’s walk/bike paths, so the surface is smooth and the surroundings are scenic. It’s mostly flat, which makes it approachable for runners and walkers of all paces. The field tends to be a warm, community crowd rather than a competitive one. Orangetheory Fitness of Long Island is the presenting sponsor, so expect a little extra energy in the staging area.

The event has grown to include a lot of extras: age group medals, cancer fighter and survivor recognition, face painting, games, and a post-race beer from Lunchbox Brewing Company for participants 21 and over. T-shirts and finisher medals are guaranteed for the first 500 registrants. Plan to arrive between 7:30 and 8:30 AM for packet pickup.
