    Race Strategy

    Focus on maintaining a steady effort through the rolling hills, conserving energy on the downslopes while managing your pace on the climbs. Aim to hit negative splits in the second half once you've settled into your rhythm, as the course's later miles may provide opportunities to pick up the pace.
