All about sports nutrition

Fuel your Long Course Weekend journey

Long Course Weekend Belgium demands a lot from your body. Swimming, cycling, and running. Spread over multiple days. Whether you choose one discipline or combine them, one thing is certain: sports nutrition can make or break your weekend.
Good sports nutrition isn’t about tricks or hype. It’s about giving your body what it needs, at the right time. Energy to keep going. Support to stay sharp. And recovery so you can show up strong again the next day.en.

That’s why we work together with up4™ as our official sports nutrition partner.

Why sports nutrition matters so much

During the Long Course Weekend Belgium, your body is used very differently than in a regular training session.
Longer efforts. Multiple days in a row. Different disciplines. That calls for smart choices.

During the swim
You often start fresh, but your body immediately switches to energy consumption. Proper preparation ensures you don’t exit the water already depleted.

On the bike
This is where the difference is made. Long periods in the same position, continuous energy use. Without enough fuel, your pace, focus, and enjoyment quickly fade.

After the run or at the end of your day
Recovery determines how you feel the next day. Recovering well means less muscle soreness, more energy, and renewed confidence at the start line.
Sports nutrition doesn’t just help you go faster, it helps you perform more consistently throughout the entire weekend.

Energy, recovery, and support

Sports nutrition can sound complicated, but in reality it comes down to three basic needs:

Energy
During prolonged exercise, your body mainly runs on carbohydrates. Without replenishment, your stores run out, and you feel it immediately. up4™ helps keep your energy levels stable, without a heavy stomach or energy crashes.

Recovery
Recovery isn’t a luxury; it’s an essential part of performance. Taking the right nutrients after exercise helps your muscles recover faster and prepares you for action the next day.

Support
Think of support for your muscles, tendons, joints, and overall resistance. Especially during a multi-day sports event, this foundation is crucial.

up4™ deliberately structures its products around these three moments, so you always know what you need before, during, or after your sporting effort.
