21k Run Stirling: Journey Along the Historic Antonine Wall

Route Overview & Local Insights

Stage 3 of the legendary John Muir Way offers runners a remarkably fast and rhythmic 21.0km point-to-point journey through the Stirling countryside. Boasting a predominantly flat profile with 90% paved surfaces, this route is a dream for those looking to maintain a steady tempo. You’ll spend the bulk of your miles gliding along the well-maintained Strathblane Railway Path and the tranquil banks of the Forth and Clyde Canal. While the straightaways through the Dumgoyne and Strathblane valleys provide a meditative running experience, stay alert as you approach the finish; the final climb over Castle Hill introduces a refreshing change of pace and some punchier elevation to test your legs at the 112m ascent mark.

Running this stretch is like traversing a timeline of Scottish history. As you skirt the vibrant Dullatur Marsh—a haven for local birdlife—you are actually following in the footsteps of Roman legionnaires and industrial pioneers. The route culminates at the Antonine Wall, a UNESCO World Heritage site and the northernmost frontier of the Roman Empire. Passing the ancient earthworks near Croy provides a powerful sense of place that few trail runs can match. This stage perfectly captures the spirit of John Muir himself: a seamless blend of natural observation and the quiet persistence of moving through a historic landscape.
