Prepare for crisp morning temperatures around 8-11°C, warming up to 22°C by the afternoon. Dress in layers for the morning transition and use standard cooling strategies if the afternoon sun breaks through.
Target 60-90 grams of carbohydrates per hour on the bike. Even in cooler spring conditions, aim for 500-750 ml of fluid per hour to offset sweat loss from the rolling terrain.
Start the cool river swim controlled to manage your breathing. On the bike, ride defensively through the rolling sections to save energy for a fast, flat riverfront run.
A full wetsuit and neoprene cap are highly recommended for the cool river swim. Opt for a versatile mid-depth wheelset to balance aerodynamics with potential crosswinds on the bike.
