Surface source (opens in a new tab) checked 15 September 2026. The official half-specific guide describes roads, the Limehouse road tunnel, a short cobbled area in Wapping and Tower Bridge. These are paved road-course features. The current 2027 event links this stable course guide; individual sections are not separately dated 2027. Cobbles remain road, not an invented trail percentage.
