Passo Garlenda

Passo Garlenda cycling climb profile

Passo Garlenda is an HC climb that asks for patience more than aggression. The headline number is 28.7 km at 6.22%, but the more important detail is how cleanly the elevation gain is delivered. It starts at 348 m and reaches 2,135 m, with 1,787 m of net elevation gain and 1,795 m of total ascent. That tiny gap between net gain and total ascent tells you the climb is not giving much back. There is very little meaningful descending hidden inside the profile.

That makes Passo Garlenda feel less like a climb you can game through repeated recoveries, and more like a long, sustained load. The average gradient is manageable on paper, but over this distance it becomes a durability test. A rider who treats the first half like a tempo climb can easily find the final portion turning into a slow grind.

How the gradient unfolds

With only the headline profile available, the safest reading is that Passo Garlenda trends upward almost continuously from bottom to summit. The average gradient of 6.22% points to a mostly rideable climbing rhythm, while the 10.63% maximum gradient matters because it changes the pacing problem. You are not just riding a steady 6% road for 28.7 km. You need enough margin to absorb steeper ramps without repeatedly crossing too deep into the red.

The total ascent figure is the key tactical clue. Since total ascent is only slightly higher than net elevation gain, any flatter or easier moments should be treated as chances to reset pressure on the pedals, not as full recoveries. On a climb this long, even small surges compound. The cost is not always immediate, but it tends to show up near the summit when cadence drops and every percentage point of gradient feels heavier.

Pacing and gearing notes

Ride Passo Garlenda by effort, not by the average gradient. The 6.22% average can tempt a strong rider into settling near /glossary/ftp too early, but the climb is long enough that threshold-style pacing needs to be used carefully. A better approach is to hold a controlled endurance-to-tempo effort early, keep breathing stable, and save harder work for the upper part when the summit is actually within reach.

Gear for the maximum gradient, not the average. The steepest pitch reaches 10.63%, and after a long accumulation of climbing, that will feel very different from the same ramp on fresh legs. A compact climbing setup or a cassette with a generous low gear is not defensive here - it is the tool that lets you keep cadence under control when fatigue starts to narrow your options.

Practical pacing cues:

• Start easier than the profile suggests. The climb gains 1,787 m net, so early overpacing is expensive.
• Use any easing in gradient to lower torque and refocus, not to accelerate automatically.
• Stay seated when possible on the steeper ramps to avoid burning matches too early.
• If riding with power, cap surges and keep the effort below a level you cannot repeat late in the climb. Use /tools/ftp-estimator if you need a working benchmark.

Passo Garlenda is not defined by one brutal statistic. It is the combination of length, near-continuous elevation gain, and enough steepness to punish poor pacing that makes it a serious HC ascent.
