Col de Targouts cycling climb profile
The Col de Targouts is a long, energy-draining Category 1 climb rather than a short gradient test. At 17.8 km, with 944 m of net elevation gain and 1060 m of total ascent, it asks for patience before it asks for aggression. The average gradient of 5.29% looks manageable on paper, but the maximum gradient of 11.03% changes how the climb should be ridden.
That gap between the average and the steepest ramps is the key. A steady 5.29% ascent can be ridden near rhythm if the rider is fresh and geared correctly. But once the road pitches into double digits, the cost of small pacing errors rises quickly. The climb is long enough that burning matches early will not just hurt on the steepest sections - it will compromise the final third, where accumulated elevation gain becomes the real opponent.
How the gradient unfolds
The climb starts at 109 m and finishes at 1053 m, so the profile gains substantial height from a low starting point. The total ascent being higher than the net elevation gain suggests the road is not perfectly uniform. There is likely some terrain variation across the climb, meaning the rider should expect changes in pressure rather than a single metronomic slope.
This matters tactically. On a climb with an average gradient just over 5%, it is easy to treat the lower-gradient sections as recovery or as places to push. The smarter approach is to use them to stabilize effort. If the road briefly eases, keep the torque low, reset breathing, and prepare for the harder pitches. The 11.03% maximum gradient is steep enough that arriving under-fueled, over-geared, or already above sustainable effort will turn the climb into damage control.
Pacing strategy
The Col de Targouts rewards controlled riding. For riders using /glossary/ftp as a pacing anchor, the first priority is avoiding repeated surges above sustainable power before the steepest sections. The length makes this a climb where perceived effort lags behind reality early on. It can feel comfortable while the metabolic cost is already building.
A practical pacing model:
- Start conservatively and let the climb come to you.
- Keep pressure smooth through the mid-gradient sections around the climb's average.
- Save a gear and some cadence for the 11.03% ramps.
- Use any easing in the road to recover, not to chase speed.
- Lift the effort only once the summit is close enough that a fade is unlikely.
Gearing and ride feel
Because the average is moderate but the maximum gradient is severe, gearing should be chosen for the steepest moments, not the headline average. A rider who gears only for 5.29% risks being forced into low cadence grinding when the road kicks up. That can spike muscular fatigue and make the remaining distance feel much longer than the profile suggests.
The best setup is one that allows seated climbing through sustained gradients while still leaving a bailout gear for the sharpest pitches. Smooth cadence matters more than forcing a big gear. On this climb, the winning move is not brute force early. It is keeping enough control that the final kilometers are still a climb, not a survival exercise.
