Race Day at Westfriesland: Timeline, Common Mistakes, and Backup Plans

Friday and Saturday: The Days Before

Bike check-in is scheduled for Friday or Saturday (check the exact times for this year's edition in the official athlete guide). Use these days for three concrete things.

First: scout the swim. The course in Hoorn harbor has lots of turns — about 8 in 2023 — and a final passage under a narrow bridge, reported as chaotic. Study the buoys from the quay, memorize landmarks on shore, figure out where the course exits the breakwaters into open water.

Second: if you can, drive or ride past the cobblestone section in the center of Medemblik and a stretch of the dike, to know what's coming. Third: check that bottles, bottle cages, and your repair kit are tightly secured before racking your bike. Cobbles don't forgive poorly fastened gear.

English signage in 2023 was sparse: print or save maps and schedules, don't rely on the signs.

Sunday Morning

In 2021 transition opened at 07:00: assume a similar time but verify it. If you're staying in Hoorn, walk there; if you're staying in Heerhugowaard, factor in the 20-minute drive plus parking plus the walk, and add half an hour of buffer.

In transition: pump your tires, mount your bottles, double-check all fastenings. Transition is on the soccer field at Hollandia Park, on grass: memorize your row with a fixed landmark, because after the swim your brain runs at half capacity.

It's a rolling start: seed yourself by your actual swim time, not your ego. With a course full of turns and that narrow bridge at the end, starting too far forward means getting swum over in the worst spots. Water temperature averages around 17 °C (17.8 °C in 2021, wetsuit legal): plan a short warm-up and get used to entering cool water in your wetsuit beforehand.

The Mental Sequence of the Race

Swim: single 1.9 km loop, inside the harbor and then out past the breakwaters, where you may find chop. Then 200 meters of running on carpet to transition. Bike: 90 flat km where the wind calls the shots — push into the headwind, recover with the tailwind, and reach the final dike (last ~20 km, exposed) with something in reserve. Run: flat half marathon on loops through the town center, first lap controlled.

The Common Mistakes

Four mistakes come up repeatedly in race reports. One: burning matches in the tailwind sections chasing average speed, then blowing up on the dike. Two: losing your line in the swim — with 8 turns, every missed buoy costs you. Three: counting on the run aid stations: in 2023 some ran out of isotonic drink and, at times, water. Start with your own gels and, if it's hot, a flask. Four: underestimating the Medemblik cobbles and losing a bottle halfway through the bike.

Wind Backup Plan

If it's windy in the morning (the historical average is ~17 km/h, but it can be much more), revise your targets: drop your watts on the headwind sections just enough to reach the run with legs left. On this course a windy day adds minutes for everyone: your relative ranking doesn't change, but your race does — if you manage it better than everyone else.

Heat Backup Plan

Typical weather is mild (14-21 °C), but there have been editions with unusual heat. If the forecast says above 25 °C: water over your body at every aid station, ice if available, more conservative run pace from the first lap. Decide your Plan B trigger threshold the night before, with a clear head.

One Last Thing

Cutoff times aren't published in the sources consulted: verify them in the athlete guide. And enjoy the finish: the laps through Hoorn's historic center, with the crowd right on top of you, are why this race is worth the trip.
