Maguryeong

Maguryeong cycling climb profile

Maguryeong is a compact but legitimate category 2 climbing effort: 8 km from bottom to summit, rising from 169 m to 651 m for 482 m of net elevation gain. The average gradient is 5.99 percent, which puts it in that awkward middle ground where it is too sustained to treat like a roller, but not steep enough to force a survival pace from the first pedal stroke.

That is the key to riding it well. The average tells you this is primarily an aerobic climb, but the 11.52 percent maximum gradient changes the cost of poor pacing. If you ride the opening like a short hill, the steeper pitches will arrive with too much lactate already in the legs, and the climb will feel much longer than its 8 km length suggests.

How the gradient rides

The available profile data does not give a corner-by-corner gradient breakdown, so the cleanest reading is to treat Maguryeong as a steady 8 km ascent with intermittent steeper pressure. The climb gains its height efficiently: 482 m of net elevation from start to summit, with a listed total ascent of 456 m. Either way, the profile is defined by sustained upward work rather than repeated descents and resets.

At 5.99 percent average, most of the climb should sit in a rhythm-climbing zone for a trained rider. The problem is not the average. The problem is the gap between the average and the 11.52 percent maximum. That spread means the hardest sections are nearly double the climb's average pitch, so cadence and gear choice matter. A rider who is comfortable at threshold on a steady 6 percent grade can still get dragged over target when the road kicks up.

Pacing strategy

Ride the first part below your intended climbing ceiling, especially if using /glossary/ftp as your anchor. Maguryeong rewards patience because its 8 km length gives plenty of time for early overpacing to compound. The correct effort should feel controlled at the bottom, purposeful through the middle, and only fully committed near the summit.

A practical approach:

• Start seated and smooth rather than chasing speed on the lower slopes.
• Keep a gear in reserve for the 11.52 percent maximum ramps.
• Use the average gradient as the pacing reference, but respect the max gradient as the limiter.
• If riding by power, avoid repeated surges above your target unless the steep pitch forces it.

Gearing notes

Maguryeong is not a pure wall, but it is steep enough in places that over-gearing will be expensive. The ideal setup is one that lets you hold cadence on a sustained 5.99 percent climb while still having bailout range for the steepest ramps. If your easiest gear only feels comfortable on moderate gradients, the 11.52 percent sections will likely force a low-cadence grind.

For training, this is a useful climb because it blends steady aerobic load with short strength demands. For performance, the decisive skill is restraint: ride the average, prepare for the ramps, and save the real effort for the upper part of the climb.
