Running safely and responsibly
Not replacing fluids lost through sweating during endurance sports can lead to loss of performance. Not drinking sufficiently can ultimately lead to medical problems. Many athletes appear not to know that not only not drinking enough but also drinking too much endangers their health. Keeping the correct level of fluids and salts in the body is very important. When you run your body loses fluids and salts via your sweat through the skin and via your breath. These processes ensure you remain cool and that your body temperature is kept stable. Not replacing the correct amount of fluids on time can lead to dehydration (drinking too little) and hyponatremia (drinking too much and having too little sodium). This can affect your performance, your psyche and your physical state. The correct level of fluids and sodium in the body is an individual matter and is dependent on the environmental conditions (the weather), they type and intensity of the activity (speed) and personal factors such as level of training, body weight and clothing you wear. Athletes have a personal responsibility in this. Drinking the correct amount is a combination of knowing your body's needs and the way you drink while running.

1/4 Marathon Rotterdam (10,55 km)
During the ¼ Marathon Rotterdam there will be a drinks station at 5 K with sports drinks (AA Drink) and water. Directly after the finish there will be AA Drink sports drink, water and fruit available.

Is there a time registration?
Only at all parts of the NN Marathon Rotterdam on Sunday the MYLAPS BibTag will be used to register time. On the back of your starting number (Bib) is an electronic chip (Tag) and a plastic spacer. BibTag makes it very easy to register your times, the only thing you have to do is wear the start number correctly.

Information to ensure proper time registration:

• Wear the start number visibly on the chest. 
• Do not cover the start number with a jacket or with your hands while passing the mats on the start and finish line. These mats will catch the signal from your BibTag (also be careful when pressing your own stopwatch on the start and finish line).
• Do not fold or crumple the start number. Certainly not where the Tag is.
• Use four pins at the corners of the starting number, don't pierce the Tag.
• Do not remove the plastic spacer.
• The BibTag is based on a different technology than the MYLAPS ChampionChip. Therefore, you cannot use your yellow or green MYLAPS ChampionChip during this event. However, you can leave your MYLAPS ChampionChip attached to your shoe, it will not interfere with the BibTag system.

What is the official time?
Gross time is official time. It starts the moment the starting shot is given and stops the moment you pass the finish line. Net time is the time that starts when you pass the mat on the starting line and stops when you cross the finish line. The net time is given as an extra service.
