Steady climb, cool finish ahead

Runners will face a temperature rise from 52°F at the start to 71°F by the finish, with average humidity at 63%. A light crosswind will challenge the early miles, shifting to headwind from mile 11 to 14 and again from 16 to 25, so pacing adjustments will be essential. With a significant descent from mile 15 to 26, runners should capitalize on this stretch while managing their effort in the headwind segments.
