It’s Memorial Day, the unofficial start of summer, and what better way to celebrate than in the sun, running around New York’s wonderfully weird Roosevelt Island? The Memorial Day Ice Cream Social 5K and 10K Races mark the beginning of NYCRuns’ 2015 season. Awards will be given to the top three male and female runners in each race, broken down into age groups ranging from 10 to 70 years old. In case you’re wondering about the second, more tantalizing part of this event’s name, then yes, an ice cream social awaits at the finish line. Whether that’s an amazing idea or a terrible, potentially vomit-soaked idea, we don’t know. But we can tell you that there’s probably no better motivation to finish than a big old sundae — and hell, you deserve it, put those calories right back in you, champ.
