Cool start, gradual warm-up

Runners will face a temperature rise from 53°F at the start to 63°F by the finish, with humidity averaging 68%. Light winds from the SSW will be a non-factor, though there will be segments of headwinds between miles 11-22. Runners should start conservatively as the humidity may impact performance, particularly on the rolling course where pacing adjustments will be crucial.
