Paso de Bariloche

Paso de Bariloche cycling climb profile

Paso de Bariloche is a category 1 climb in Argentina, and the numbers explain why it deserves respect. The climb runs for 8.2 km, rising from 813 m to 1418 m, with 605 m of net elevation gain and 621 m of total ascent. The average gradient is 7.36%, but the key detail is the maximum gradient of 18.5%.

That combination tells you this is not a climb to pace purely off the average. A steady 7.36% for 8.2 km is already a meaningful aerobic effort, but the presence of ramps up to 18.5% changes the ride completely. Those steeper sections will force torque, disrupt cadence, and punish anyone who is already riding at or above threshold.

How the gradient unfolds

The total ascent of 621 m compared with 605 m of net gain suggests the road is mostly committed uphill, with only limited relief across the ascent. There may be small variations in pitch, but the profile is not defined by long recovery sections. The climb is better approached as a sustained effort where the gradient can bite hard rather than a stair-step climb where each ramp is followed by meaningful rest.

The 18.5% maximum matters tactically. Even if that steepest pitch is brief, it raises the cost of over-pacing the lower slopes. A rider who starts too hard on a climb of this length will not just fade gradually - they will arrive at the steepest gradients without the torque reserve needed to keep the bike moving smoothly.

Pacing and gearing notes

Treat Paso de Bariloche as a controlled threshold climb with anaerobic spikes layered on top. The smartest ride is to settle early, keep breathing under control, and avoid chasing speed when the road feels merely hard rather than severe.

Practical approach:

• Start below your target climbing effort until the rhythm of the road is clear.
• Save a gear for the steepest ramps, because 18.5% is steep enough to make cadence management the limiting factor.
• Stay seated where possible to conserve energy, but be ready to stand briefly if the pitch forces it.
• Avoid using the average gradient as permission to overgear. The climb may average 7.36%, but it asks for a setup that can handle much more.

If pacing by power, this is a climb where knowing your /glossary/ftp helps, but the execution still has to respect the gradient changes. The goal is not to produce the highest early number. It is to arrive at the steepest sections with enough control to keep pressure on the pedals without tipping into a costly red-zone effort.

Bottom line

Paso de Bariloche is long enough to demand endurance, steep enough to demand low gearing, and consistent enough that mistakes compound. Ride the first part with restraint, protect cadence whenever the road kicks up, and let the climb come back to you rather than trying to force it from the bottom.
