Tim Brennan has ran more than 90 miles across The Netherlands in 19 hours as part of his major performance art project to trace the edge of the Roman Empire across the globe. He completed a solo run along the edges of the Roman Empire in Continental Europe, which he began at 3am on Saturday (August 24) taking the road east from Katwijk- Aan-Zee, on the edge of the North Sea to Herwen-De-Bijland, near the German border and the Black Sea, known as the Lower Germanic Limes (frontier).
