Collado Somero cycling climb profile
Collado Somero is a short, concentrated Category 3 climb in Spain. On paper, it is 2.2 km long at an average gradient of 7.82%, rising from 1105 m to 1277 m for 172 m of net elevation gain. That profile tells you most of what matters: this is not a long endurance climb, but it is steep enough for the effort to bite almost immediately if you ride it like a rolling rise.
The key feature is the relationship between the average gradient and the maximum gradient. With the climb averaging 7.82% and topping out at 9.98%, the road does not need a standout wall to become selective. The average is already high enough that most of the climb should be treated as sustained climbing, while the steepest pitch is close enough to double digits to punish any early overreach.
How the gradient unfolds
With only the overall profile available, the safest reading is that Collado Somero is compact and fairly direct rather than a climb with a long, gentle lead-in and one isolated sting. Over 2.2 km, there is not much room for the gradient to hide. If the average is 7.82%, any easier section has to be paid back somewhere else, and the listed maximum of 9.98% means those payback moments are likely to feel sharp without becoming extreme.
That makes it a rhythm climb, but not a passive one. The effort is short enough that stronger riders may be tempted to force the pace from the base, yet the gradient is high enough that a small pacing error can put you into the red before the summit is close enough to justify it.
Pacing and gearing notes
Start controlled. The opening minutes should feel firm but sustainable, especially if Collado Somero comes inside a longer ride or after previous climbing. Use the early part to settle cadence and breathing rather than trying to bank time.
A compact climbing gear is the practical choice. The maximum gradient of 9.98% is not outrageous, but on a 2.2 km climb averaging 7.82%, overgearing turns the whole ascent into a low-cadence grind. If you have to stand, it should be a choice to smooth a steeper pitch, not a rescue move because the gear is too big.
For pacing, think in terms of controlled pressure until the final portion, then lift only once the summit effort is clearly manageable. Riders using power should anchor the climb around sustainable threshold-style output rather than chasing every change in pitch. If you need a reference point, use /glossary/ftp or estimate your number with /tools/ftp-estimator before trying to pace it by feel.
Collado Somero is short, but it is not casual. Its difficulty comes from density: 172 m of net gain packed into 2.2 km, with little margin for lazy gearing or an impatient start.
