IRONMAN Westfriesland
The Westfriesland 70.3 starts with 1,900 m in the old harbour at Hoorn, then heads out for 90 km on the flat polder roads north of Amsterdam before 21.1 km through the historic town centres.
Flat does not mean fast here. The Dutch landscape has nothing above head height to break the weather, and a steady wind on an exposed dyke road is the entire race. In a still year this course produces personal bests. In a windy one it produces a lot of unhappy power files and finishing times half an hour off target.
Plan a bike pacing strategy in two versions and pick one at the start line rather than committing to a number in advance.
The compensations are real: cobbled town centres on the run, windmills that are actually on the route rather than in the marketing, and an hour's train ride from Amsterdam Schiphol to the race town.
