London Marathon
London Marathon is a flat marathon in London, UK, held each April. A fast, largely flat point-to-point from Greenwich to The Mall, with crowds nearly the whole way. Typically cool and changeable — roughly 8-14C, with rain always possible in April. Flat courses like London's reward metronomic pacing — the danger is going out faster than goal pace because it feels cheap early.
