Steeped in industrial heritage, the Northampton Arm of the Grand Union Canal was originally opened in 1815 to connect the main line to the River Nene. Running this stretch takes you past a series of historic locks—17 in total along the full arm—which served as vital arteries for trade during the 19th century. As you reach Gayton Marina, you are entering a significant junction where the Northampton branch meets the main Grand Union Canal route. Local runners often favor this path not just for the lack of traffic, but for the sense of history that lingers around the old brickwork and timber lock gates, offering a glimpse into Northampton’s past as a bustling transport hub long before the era of motorways.
