Cool temps, strong winds ahead

Runners will face temperatures starting at 56°F and peaking at 59°F, with high humidity at 83%. Wind will be a significant factor, particularly with strong gusts up to 39 mph, creating challenging crosswinds in several miles. Pacing adjustments are crucial, especially during Miles 8-10 where headwinds will slow progress; runners should consider conservative starts to maintain energy through the tougher segments.
