Official event pageWhat this race demands
This 10-mile spring road race requires sustained aerobic pacing over a distance significantly longer than a standard 10K. Athletes must manage their output across the early-season endurance test.
Aerobic Endurance
Covering 16.1 kilometers requires a high level of aerobic conditioning, extending well beyond typical middle-distance training volumes.
Pacing Discipline
Sustaining a consistent effort across a 10-mile road course demands strict adherence to target splits to avoid early fatigue in the spring conditions.
