Volunteer. And party.
Run (or walk) around Prospect Park.
The Prospect Part Walk-a-thon is still on for Saturday, November 3, and all proceeds will go to repair the damage the park sustained after Hurricane Sandy (like this splintered tree).

Runners looking for a physical challenge can also lug food and water to and from shelters or participate in a number of other relief efforts going on across the city.
