You step out of Baker Street tube into a London that still leaks gaslight in its shadows: cobbled side lanes, clipped hedges, and the low hum of a city that never quite sleeps. The game pings your phone and Holmes' voice — or his challengers — begins to narrate your first clue. The route pushes you through Marylebone's narrow streets and into the wide, tree-lined crescents of Regent’s Park, a 5 km loop that moves at the pace of your curiosity.
