Cool conditions, adjust for wind

Runners will face temperatures starting at 42°F and rising to 45°F by the finish. With a steady NW wind at 13 mph and gusts up to 31 mph, pacing strategies should account for the headwind effect. Given the cool temperatures, runners may benefit from a throwaway layer before the race, though hydration remains key.

About the Colonial Half Marathon

The Colonial Half Marathon is run each February in Williamsburg, Virginia. It starts near Nassau and Francis Streets, passes the Governor's mansion and the Capitol in Colonial Williamsburg, then runs out and back on Carters Grove Country Road and finishes by climbing Fortitude Hill. A ruck division runs the same course, and a 5K is held the same morning. The half has a 3.5 hour time limit.
