Steady conditions, wind challenge ahead

Runners will face a consistent temperature of 60°F throughout the race, with average humidity at 76%. Wind from the NW will create headwinds during several segments, particularly in Miles 2, 6, 15, 19, and 22, requiring strategic pacing adjustments. Hydration should be prioritized given the humidity, and runners may want to employ a conservative start to manage energy against the wind.
