Moll's Gap

Moll's Gap cycling climb profile

Moll's Gap is a category 4 climb in IE that rewards rhythm more than raw climbing power. On paper, it is 6.6 km long, rises from 64 m to 262 m, and gains 198 m net elevation. The average gradient is 3%, with a listed maximum of 4.24%, which tells you almost everything important about how to ride it: this is a shallow, sustained ascent where speed control, position, and pacing discipline matter more than surviving steep ramps.

How the gradient rides

The climb starts at 64 m and finishes at 262 m, so the work is spread across the full 6.6 km rather than concentrated in one decisive wall. With an average gradient of 3% and a maximum of 4.24%, the gradient ceiling is low enough that most riders will not need to shift into true climbing survival mode.

That does not make it free. A shallow climb can be deceptively costly because it tempts riders to press too hard early. At this gradient, momentum stays high, and the effort can feel closer to a hard false-flat drag than a classic mountain climb. The danger is riding it like flat terrain until the accumulated load catches up halfway through.

The listed total ascent is 185 m, while the net elevation gain is 198 m. The practical takeaway is the same either way: the profile is defined by a modest vertical gain over a moderate distance, not by repeated steep changes. Expect a climb where holding steady pressure is more valuable than surging.

Pacing strategy

The best approach is to settle quickly into an effort just below the level you would use for a short, steep climb. Because the maximum gradient is only 4.24%, there is little reason to spike power unless the road or group dynamic forces it. If riding with power, anchor the effort around sustainable climbing intensity rather than chasing speed moment to moment. For guidance on setting that ceiling, use your /glossary/ftp as the reference point.

A useful pacing rule here is simple: if the first part feels easy, let it. On a 6.6 km climb at 3%, the cost of going slightly too hard is not dramatic in the moment, but it compounds. Keep the pressure smooth through the middle of the climb, then lift the effort only once the summit at 262 m is clearly coming into range.

Gearing and technique

Moll's Gap does not demand ultra-low gearing from the profile alone. The shallow average and limited maximum gradient mean most riders should be able to stay seated, keep cadence stable, and avoid grinding. The priority is having a gear that lets you apply continuous pressure without dropping into a low-cadence torque effort.

Because the gradient is moderate, aerodynamics and rolling speed still matter. Staying compact, avoiding unnecessary accelerations, and keeping the bike moving smoothly will often be faster than riding it like a steep climb out of the saddle. Treat Moll's Gap as a controlled endurance test: steady gear, steady breathing, steady power, and no early heroics.
