There will be a run in Central Park tonight in honor of Doug Stern. Details:

To enter, all you need to do is buy a jingle bell from Mike Keohane for $10 (all of which goes to Memorial Sloan Kettering Cancer Center) and then show up, in costume or not, between 6pm and 7pm — right before the regular workout — on the reservoir and run in memory of Doug. This is a fun run — it will be untimed, uninsured, unmanaged, un-porta-sanned, un-everything. The way it s supposed to be.
