2026 Jovia Financial Credit Union Long Island Marathon Weekend. There are few events on this great island that are as iconic and long-standing as the Jovia Long Island Marathon, which has evolved from a small road race that attracted avid runners more than 52 years ago, to a 3 day-long festival for kids, families, and the entire community. The weekend includes a 1k KIDS Fun Run, 5k Night Light run/walk, 10k Run, Half & Full Marathons.
