As you no doubt have seen, weather conditions may be a factor for the Saturday Long Run tomorrow.
Weather.com predicts snow, changing to a "wintry mix" overnight, with sub-freezing temps and freezing rain/ice from 3am on into the morning hours.
As of now, the SLR is still on as planned, however, if there is already an accumulation of ice on paved surfaces as of 7:00am tomorrow morning (and the ice/sleet continues) there will be an "unofficial" SLR at the usual time and place. I will not be there and may disavow any knowledge of your actions, so run at your own risk using caution at all times; post-run beverages also might not be present.
The planned SLR Itinerary is the DC Sightseer route, with options from 9 up to 18 miles. Cross your fingers that its only rain and we will be on as planned.
