Cycling the Trough of Bowland: climb profile and Lancashire route guide

The Trough of Bowland is one of Lancashire’s best-known cycling climbs, but the name can be slightly misleading. It is part of a much bigger stretch of road through the Forest of Bowland National Landscape, with the recognised eastern climb from the Dunsop Bridge side covering about 2.1km at an average of 6% and reaching roughly 16% near the top.

Its reputation owes as much to the setting as the numbers. The roads around Dunsop Bridge, Marshaw and Jubilee Tower are quiet, exposed and repeatedly rolling, making the Trough a natural centrepiece for a longer ride rather than a climb you travel to just for two kilometres.

What the eastern climb is like

The recognised climb approaches from the Dunsop Bridge side. The first kilometre is deceptive, with gentle gradients and small rises that make the 6% average look easier than the climb eventually feels.

The road then tightens as it enters the actual trough. Eight per cent becomes normal, with the hardest ramps reaching the mid-teens. The final 400 metres are the section that turns it from a scenic lane into a proper climb.

The pay-off is the view opening behind you as the road nears the summit. It is one of those climbs where looking back on the steep section is almost as good as the descent on the other side.

The western approach from Marshaw

Coming from the west gives a very different ride. The longer approach from Marshaw spends much more time beside the stream and gains height gradually before the final ramps towards the pass.

It is less dramatic on paper but works brilliantly in a loop because the road feels continuously remote without becoming relentlessly steep. The descent towards Dunsop Bridge is fast and open in places, then more technical as the bends tighten.

Why the Forest of Bowland is so good for cycling

The Trough sits inside the Forest of Bowland National Landscape, an area of Lancashire and North Yorkshire that is often quieter than the nearby Lake District. The road network is limited, but that works in a cyclist’s favour: there are long stretches where traffic is light and almost every route contains repeated climbing.

The National Landscape currently publishes a dozen cycling routes covering road, gravel and mountain-bike options, including loops from Lancaster, Scorton, Waddington and Slaidburn. That makes the Trough useful as one part of a wider weekend rather than a standalone tick-list climb.

Dunsop Bridge, Jubilee Tower and nearby climbs

Dunsop Bridge is the obvious café stop and route junction on the eastern side. Heading west brings Jubilee Tower into play, another climb included in Simon Warren’s 100 Greatest Cycling Climbs. Combining the two gives a much harder day than either profile suggests on its own because the roads between them rarely stay flat for long.

The wider Bowland lanes have also featured in local racing, including the Lancaster Grand Prix. ProCyclingUK’s 2019 Lancaster Grand Prix gallery shows some of the same roads in race conditions.

Best time to ride the Trough of Bowland

Late spring to early autumn gives the best chance of dry roads and long daylight, but Bowland weather can turn quickly. Exposed sections catch wind and the shaded lanes can stay wet after rain.

Winter riding is possible, but ice and standing water make the descents much less forgiving. Check the forecast for the higher ground rather than assuming conditions in Lancaster or Clitheroe will match the pass.

What bike and gearing do you need?

A normal road bike is ideal for the main Trough road. A compact or semi-compact setup with a 30-tooth or larger sprocket gives enough range for the steeper finish without compromising the faster roads around it.

If the day includes the National Landscape’s gravel routes or Gisburn Forest, a gravel or mountain bike becomes the better tool. The important point is deciding the whole route first rather than choosing a bike purely for the Trough itself.

A useful book for planning more UK climbs

The Trough and nearby Jubilee Tower are both well established on British climbing lists. Simon Warren’s 100 Greatest Cycling Climbs is available on Amazon UK if you want to build a wider trip around similar roads.

Is the Trough of Bowland worth riding?

Definitely. The climb itself is not among Britain’s longest or steepest, but the surrounding roads turn it into a much better cycling destination than the headline 2.1km suggests.

Ride it as part of a Bowland loop, include Jubilee Tower if the legs are good and leave enough time for the quieter lanes around Dunsop Bridge. The strength of the Trough is not one savage gradient. It is the quality of the whole riding area around it.
