Cold start, wind challenges ahead

Runners will face steady temperatures around 39°F throughout the race, with a wind from the WNW reaching up to 14 mph. The humidity at 66% may add a chill factor, especially in the early miles. Pacing adjustments will be essential, particularly through miles 4, 6-8, and 13 where headwinds will be prominent, requiring extra effort.

Race Info

The Naptown Half Marathon starts and finishes at Navy-Marine Corps Memorial Stadium in Annapolis, Maryland, beside the US Naval Academy. The USATF-certified half marathon course runs through downtown Annapolis and out onto the Baltimore-Annapolis Trail before returning to the stadium. A 10K and a 5K start from the same place on the same Saturday morning in mid-December, and the race is holiday themed, with Santa caps for runners and prizes for the most festive.
