One landmark.
Old Billingsgate has hosted FLATOUT London before. In February it does it again, over two race days.
A Grade II listed market hall on Lower Thames Street, with the river on one side and the City on the other. Inside, the course runs the length of the hall: run sections, workout zones and the climb to the finish.
Iron, glass and river light. A start line in the middle of London.
Friday or Saturday, you pick your day at checkout. Every format races on both days, so bring your partner, your team or your junior.
