With a total net drop of approximately 980 feet, this marathon presents one of the steepest legal drops in the country, making it a standout choice for those looking to capitalize on gravity's aid.

BMQR course profile: Downhill.
To maximize your BQ chances at the Cascade Express Marathon, start conservatively in the early miles to avoid early burnout. The downhill profile is an asset, but it can lead to quad fatigue if you’re not cautious. Focus on a relaxed form and let gravity do the work when possible. Pay attention to your pacing device, as the urge to go out too fast can be strong with the steep descent. By the halfway mark, you should have a good sense of your remaining energy to adjust your pace accordingly. Manage your nutrition and hydration diligently at the aid stations, which are crucial due to the remote nature of the course.
