What you should know
- Multi-venue setup: swim at Oude Doelenkade, T1/T2 at Julianapark, finish at Stadsstrand — walk the routes day before.
- Bike and colored transition bags must be checked in the day prior at the designated racks in Julianapark.
- Wetsuit legality depends on Markermeer temp race morning; prepare a non-wetsuit option if water exceeds 24.5°C.
- Drafting is illegal: keep 12m gap, pass within 25 seconds, or serve a 5-minute penalty at the next tent.
- Dutch coastal wind can be strong on the flat, exposed bike course — pace conservatively into headwind sections.
