Course intelligence

Athens is not “just a marathon”.

The course itself is a training input: where it climbs, where it releases, and where fatigue meets terrain.

Training implication

Course demand becomes a reason — not a decoration.

The app can increase rolling-terrain exposure because Athens requires it. But it still refuses fixed hill prescriptions until the athlete provides terrain-specific evidence.

Confidence

Coarse engineering profile

The current A01 analysis is based on sampled elevation anchors. It is good enough for engineering behavior, not for public verified metrics or real-athlete prescription.
