What this race demands

This half marathon requires sustained running capacity over a 21.1 km distance on a relatively flat rural road course.

Aerobic endurance

Covering the 21.1 km half marathon distance demands a well-developed aerobic engine to sustain an efficient pace for over an hour and a half.

Pacing discipline

The flat rural road profile allows for a steady rhythm, requiring athletes to maintain strict pacing control from start to finish to avoid late-race fatigue.

For a half marathon lasting over an hour and a half, aim to consume 30 to 60 grams of carbohydrates per hour via gels or sports drinks to maintain energy output.
