Comfortable temps, warming through the race

Mild 55°F temps at gun time mean comfortable early miles without overheating risk. Temperatures rising to 67°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing.

Race Info

The Half Marathon is eight laps of the paved 1.64-mile loop at Pace Bend Park in Spicewood, Texas, on the shore of Lake Travis. Every lap passes the start and finish area, so runners can keep their own drinks and fuel at one spot all day. The surface is fully paved with moderate climbs and gentle descents, and the field runs the same course as the marathon on the Sunday of race weekend.
