Cold start — layer up, moderate wind

Runners will start in chilly 39°F conditions — dress in layers for the corral and plan to shed early. Moderate winds around 14mph may affect pacing on open sections of the course. Moderate humidity at 66% is worth noting for effort level, especially in later miles.

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.
