There are many groups that use the park throughout the year for a myriad of different purposes.  These include Runners, Dog Lovers, Cyclists, Yoga Enthusiasts, and pretty much every conceivable activity that two or more New Yorkers can safely, and legally, participate in in the confines of Central Park. Many of these groups, or organizations, have websites that give important information about their activities and services.  Here is a list of those sites.  If for some reason I have left your group out please contact me at John at  Thanks!
