Cool conditions, strategic pacing needed

Runners will face cool temperatures starting at 39°F and peaking at 42°F. Wind speeds will reach up to 14 mph from the WNW, creating a headwind from miles 4 to 8, which may slow progress. With humidity at 66%, maintaining hydration is crucial. Runners should adjust their pacing in the headwind sections and take advantage of the tailwinds from miles 2-3 and 9-11.

Race Info

The Naptown Half Marathon starts at Navy-Marine Corps Memorial Stadium on the edge of the US Naval Academy grounds in Annapolis, Maryland. The course runs through downtown Annapolis before joining the Baltimore-Annapolis Trail and returning to the stadium. A companion 10K and 5K run alongside it on race day. The event began in 2020 as a rebrand of the longer-running Zooma Annapolis and Wayfarer's Annapolis half marathons, which had used the same December date on the Annapolis running calendar since 2008.
