Ihwa-ryeong

Ihwa-ryeong cycling climb profile

Ihwa-ryeong is a compact but meaningful category 2 climb: 4.6 km long, rising from 237 m to 546 m for a net elevation gain of 309 m. The headline number is the average gradient of 6.65%, but the more useful detail is the max gradient of 6.99%.

That tells you a lot about how this climb rides. Ihwa-ryeong is not defined by sharp ramps or gradient traps. It is defined by consistency. With the maximum gradient sitting only slightly above the average, the effort is likely to feel like one sustained block rather than a climb that repeatedly forces you out of rhythm.

How the gradient unfolds

The available profile points to a climb with a very narrow gradient range from bottom to summit. In practical terms, that means the first mistake is usually not choosing the wrong line or missing a steep pitch. It is starting too hard because the road never gives you enough of a gradient change to naturally reset the effort.

At 4.6 km, the climb is long enough that an over-eager opening can still cost time near the top, but short enough that a controlled, high-quality effort can be held if pacing is disciplined. The 6.65% average is steep enough to make aerodynamics less important than power-to-weight and cadence control, but not so steep that you should be grinding by default.

The net gain of 309 m reinforces that this is a real sustained ascent. It is not a roller disguised as a climb. Once the road tilts up, the main task is to hold a repeatable pressure on the pedals and avoid unnecessary accelerations.

Pacing and gearing notes

Treat Ihwa-ryeong as a steady threshold-style climb rather than a punchy hill. If riding it hard, settle into the effort early, check that breathing and cadence are under control, then build only if the legs are still responding in the final portion. Using FTP as a reference, this is the type of climb where going a little too deep at the bottom is rarely paid back later.

Gearing should let you stay seated and smooth at around a 6.65% grade without forcing a grind. Because the maximum gradient is listed at 6.99%, there is no clear statistical signal that you need a bailout gear for a single wall-like section. The better choice is a range that preserves cadence while keeping the effort even.

For training, Ihwa-ryeong is well suited to sustained climbing intervals, pacing practice, and testing how cleanly you can ride a constant gradient. For racing or a hard segment attempt, the best approach is simple: no early surge, no mid-climb panic, and no waiting too long to lift the pace once the summit is within reach.
