Alto de Los Toyes

Alto de Los Toyes cycling climb profile

Alto de Los Toyes is a long, category 1 climb that asks for discipline more than aggression. At 27.2 km with an average gradient of 5.32%, it is not defined by savage ramps, but by the cumulative cost of staying on the pedals for a long time while gaining 1448 m from start to summit.

The key number is the relationship between the average gradient and the maximum gradient. A climb averaging 5.32% with a steepest section of 8.73% suggests a mostly controlled ascent rather than a wall-like effort. That does not make it easy. It means the danger is pacing it like a moderate climb early, then discovering too late that the length has quietly turned a manageable gradient into a sustained aerobic test.

How the gradient shapes the ride

Starting at 1574 m and finishing at 3022 m, Alto de Los Toyes rises high enough that the upper section should be treated with respect. Even without extreme gradients, the effort can feel progressively heavier as the climb goes on. The profile points toward a rhythm climb: settle in, protect your cadence, and avoid turning the first half into a disguised threshold test.

Because the maximum gradient is 8.73%, the steeper moments are likely to be short enough to ride seated if you have the right gearing. The mistake is not the ramp itself. It is responding to every steeper pitch with a surge, then paying for those repeated accelerations over the final kilometers.

Pacing notes

Ride Alto de Los Toyes as a long steady effort. The average gradient is forgiving enough to tempt a higher pace, but the 27.2 km length makes overpacing expensive.

A sensible approach:

• Start below your target climbing effort and let the climb come to you.
• Keep pressure smooth through the moderate sections instead of chasing speed.
• Treat any pitch near the 8.73% maximum as a place to preserve rhythm, not prove form.
• If using power, anchor the ride around sustainable aerobic output rather than repeated spikes above /glossary/ftp.

The practical goal is to arrive deep into the climb with options. If you still feel controlled after the main duration has accumulated, the upper slopes are where a stronger rider can press. If you force the pace early, the same gradients will feel much steeper near the summit.

Gearing and setup

A compact climbing setup is the smart choice. The climb is not brutally steep on paper, but 1464 m of total ascent over 27.2 km means cadence preservation matters. You want enough low gear to stay seated and smooth when the road touches its steepest gradients, especially late in the ascent.

For training, Alto de Los Toyes is best viewed as a long sustained climbing benchmark. It rewards riders who can hold an efficient aerobic rhythm, manage fueling, and resist unnecessary accelerations. The numbers make the tactical lesson clear: this is a climb to meter out, not a climb to attack from the bottom.
