Tizi n'Test

Tizi n'Test cycling climb profile

Tizi n'Test is a Category 1 climb built around duration more than constant brutality. The headline is 40.5 km at 3.72%, rising from 589 m to 2096 m, with 1507 m of net elevation gain and 1545 m of total ascent. That tells you the key story before you even see the road: this is a long, mostly upward pass where the average gradient can make the effort look easier than it will feel after sustained time under load.

The small gap between net elevation gain and total ascent means the climb is not a sawtooth route full of repeated descents. It gains height efficiently. For pacing, that matters because there are likely fewer meaningful recovery sections than the low average gradient might suggest. The gradient may ease, but the ride still trends upward for a very long time.

How the gradient unfolds

With an average gradient of 3.72% and a maximum gradient of 10.79%, Tizi n'Test should be read as a climb of contrast. The majority of the ascent is moderate enough to ride seated and controlled, but the maximum gradient shows that the road has teeth. Those steeper ramps are the danger points, not because they define the whole climb, but because they can push you above sustainable power if you treat the early kilometers too casually.

There is not enough segment-level data here to place the steepest gradients at a specific point on the climb, so the smart assumption is simple: the 10.79% sections can arrive when fatigue is already building. On a 40.5 km climb, that changes the pacing equation. The objective is not to feel good at the start. It is to keep enough margin that the steep pitches do not force repeated spikes above /glossary/ftp.

Pacing and gearing notes

The best approach is a conservative aerobic start. A climb averaging 3.72% invites riders to over-gear early, especially if the road feels fast or broken by gentler sections. Resist that. The total ascent of 1545 m means the cost accumulates steadily, and any early surge has a long runway to come back at you.

Use gearing that lets you stay seated and keep cadence stable on moderate gradients, while still leaving a bailout option for the 10.79% maximum. If your lowest gear is only comfortable on shallow grades, the steep ramps will force high torque work, which is exactly what turns a long climb from controlled endurance into muscular fatigue.

A practical pacing model:

• Start below threshold and settle into a rhythm you could hold for a long climb.
• Let speed fluctuate with gradient rather than chasing it.
• Shift early before steeper ramps so cadence does not collapse.
• Save harder efforts for the upper part of the climb, once the full 40.5 km distance is nearly accounted for.

Tizi n'Test is not defined by one savage average gradient. It is defined by the combination of length, elevation gain, and intermittent steepness. Ride it with patience, and the numbers make sense. Ride it like a short climb, and the pass will expose that mistake well before the summit.
