Marine Corps Marathon
Marine Corps Marathon is a rolling marathon in Arlington, USA, held each October. The People's Marathon: early climbs in the first 10K, then a flatter monument tour of Washington DC before the final rise to the Iwo Jima Memorial. Late October is typically cool, 5-15C. With Marine Corps Marathon's constant undulation, pace by effort rather than the watch: even effort beats even splits here.
