Races 10K · Haarlem, Netherlands
Grachtenloop Haarlem
Grachtenloop Haarlem is a flat 10K in Haarlem, Netherlands, held each June. Two laps of a 5 km loop through the centre of Haarlem, a lowland city. The organiser's page shows a map but gives no street list, so the flat rating rests on the city-street route. Evening starts in June are usually mild, around 14 to 22°C, with a chance of showers. On a course as flat as Grachtenloop Haarlem, even splits are everything; the classic mistake is banking time in the first third.
