Smugglers' Pass

Smugglers' Pass cycling climb profile

Smugglers' Pass is not long, but the numbers make it clear that this is a climb defined by torque, not patience. At 2.8 km with an average gradient of 12.5%, it compresses a serious amount of work into a short window. Starting at 71 m and topping out at 422 m, it gains 351 m from bottom to summit, which is why it carries a Category 1 rating despite the modest distance.

The practical takeaway is simple: this climb asks for climbing legs immediately. A 12.5% average over 2.8 km means the road cannot afford many easy sections. Even if the gradient fluctuates, the baseline effort is already severe, and the listed maximum of 25.04% tells you there are pitches where momentum and gearing matter as much as aerobic power.

How the gradient feels

With only the headline profile available, the safest way to read Smugglers' Pass is as a steep climb with no reliable recovery built into the pacing model. The average gradient is high enough that any short easing will likely be paid back by steeper ramps elsewhere. That is the central tactical problem: the climb is short enough to tempt an over-aggressive start, but steep enough to punish anyone who rides above threshold too early.

The 25.04% maximum gradient changes the character of the effort. On ramps that steep, cadence can collapse quickly if you are over-geared, and once cadence drops, the climb becomes a repeated low-speed strength effort rather than a controlled aerobic climb. That is where riders lose time and control - not because the climb is endless, but because the steepest sections force surges that are hard to recover from on a road already averaging 12.5%.

Pacing and gearing notes

Treat the opening as a control section, not a launchpad. The full climb is only 2.8 km, but the average gradient means it will likely ride longer than the distance suggests. A good target is to settle into a hard but sustainable effort early, keeping enough in reserve for the steepest ramps.

Gearing should be chosen for the maximum gradient, not the average. A setup that feels comfortable on 12.5% may still leave you grinding when the road kicks toward 25.04%. If cadence matters to your climbing style, err on the side of a lower gear and protect rhythm rather than trying to muscle through the steepest pitches.

For riders pacing by power, this is a climb where FTP discipline matters, but so does restraint. The gradient will probably force short spikes. The goal is not to avoid them completely, but to prevent those spikes from becoming the default effort. Ride the lower slopes with control, absorb the steepest ramps without panic, and save the final commitment for when the summit is genuinely close.
