Puerto Viejo

Overview

Puerto Viejo is a category 2 ascent that stretches 11.8 km from a base at 417 m to a summit of 1062 m. That works out to 645 m of net elevation gain over the climb, with the surveyed total ascent coming in at 630 m once you account for the small levelling sections along the way. The average gradient of 5.46% places it firmly in territory that rewards rhythm over raw power: long enough to demand patience, but never so brutally steep that it forces you into survival mode. With a maximum gradient of 7.52%, the hardest ramp here stays within a range most trained riders can turn over without walking.

How the Gradient Unfolds

The defining trait of Puerto Viejo is its consistency. Spread 645 m of climbing across 11.8 km and you get a gradient that hovers close to the 5.46% average for much of the distance. There are no wild swings into double digits — the steepest pitch tops out at 7.52%, only about two points above the average. That means the climb reads as a sustained effort rather than a series of punchy shocks. Expect the middle third to feel like the true engine room, where the road settles into its work and the elevation ticks steadily upward toward 1062 m. Because the peak gradient sits so close to the mean, you can largely trust the average when you plan your effort.

Pacing Notes

On a climb this uniform, pacing is everything. Aim to ride just under your FTP for the full 11.8 km, since the near-constant 5.46% gradient gives you nowhere to hide and nowhere to recover if you go out too hard. The 7.52% max means you can afford small surges over the steeper sections, but keep them brief and settle back to a controlled tempo. If you are unsure of your threshold, run the numbers through the FTP estimator before your attempt so you can set a realistic wattage target for the 645 m of gain. Negative-splitting — starting conservatively and lifting the pace as the summit at 1062 m nears — works well on a gradient this even.

Gearing

For a category 2 climb averaging 5.46% and peaking at 7.52%, a compact setup gives you the flexibility to sit and spin. A 34×32 will handle the sustained sections comfortably for most fit riders, letting you hold cadence across the full 11.8 km without grinding. If you favour a lighter touch, carry heavy legs, or simply want insurance for the steeper 7.52% ramp, a 34×34 drops your minimum gear further and keeps your knees happy over the 645 m of climbing. Either choice suits the terrain; the deciding factor is your own strength and how fresh you arrive at the base.

Summary

Puerto Viejo is an honest, evenly graded category 2 climb — 11.8 km of steady work that rewards disciplined pacing and a compact gearing choice. With its predictable slope and moderate maximum, it is an ideal ascent for practising sustained tempo efforts.
