Prepare for cool morning air by the beach, which warms up to around 22°C by midday. Use the aid stations along the exposed seaside boulevard to throw cold water over your head and maintain a stable core temperature.
Target 60-90g of carbohydrates per hour on the bike using a fluid-based fuel strategy to combat any dehydration caused by the coastal winds. Increase sodium intake if the day turns unexpectedly warm or humid.
Keep your effort strictly capped on the Kashubian climbs, avoiding any anaerobic spikes. Save your legs for the run, where you can settle into a steady, metronomic tempo along the flat seaside boulevard.
A mid-depth front wheel (45-50mm) paired with a deeper rear disc or 80mm wheel balances aerodynamics and handling in coastal gusts. Arrive at least two days early to practice sighting and check out transition on the seaside boulevard.
