Back during August, There was a group that did feeder rides for Summer Streets in Manhattan from the Unisphere in Flushing Meadows Park. They went past Citifield to the Flushing Bay Promenade, crossed over the Grand Central Parkway via the helix overpass to 31st Drive / 108th Street to the 34th Avenue bike Lane to get to the Queensborough Bridge.

It's a nice longer-distance ride for those who want to extend a ride past the promenade.
