Runners will face a starting temperature of 65°F rising to 80°F by the finish, with humidity at 78%, prompting a conservative start. A headwind in the early miles will challenge the pace, particularly from miles 1 and 16-27, while tailwinds from miles 3-5 and 10-13 may offer brief relief. With wind gusts reaching 37 mph, strategizing gear and hydration will be crucial for maintaining performance.
