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.

AA Drink 1/4 Marathon Rotterdam (10,55 km)

During the AA Drink 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.

City Run Rotterdam (4,2 km) & NN Kids Runs (1 & 2,5 km)

Directly after the finish there will be AA Drink sports drink and water available.

Where is the finish located?

The finish is in front of the Stadhuis (town hall) on the Coolsingel. After passing the finish line, you will be asked to carry on running to ensure that the stream of runners can flow smoothly. So do follow the organiser’s instructions strictly at the finish.

Depending on the temperature, at the care area after finish you will receive a plastic sheet, your medal and further care. There are tents in which you can obtain water, AA Drink Iso-Lemon, bananas and tea. The cordoned area behind the finish is only accessible for participants and organizers, and not for spectators or supporters.

Are there shower facilities?

No. There are no shower facilities in the marathon weekend.

Can I personalize my medal?

Yes, you can personalize your medal immediately after you finish with your name and finish time. If you’d like this, tick the ‘engrave medal’ box on the registration form. On Saturday this costs € 5.00 for the City Run Rotterdam and the NN Kids Runs and costs € 7.00 on Sunday for the AA Drink 1/4 Marathon Rotterdam and NN Marathon Rotterdam.

If you didn’t indicate this in advance during registration, you can have your medal engraved afterwards, but it will then cost € 8.00 for the NN Marathon Rotterdam and AA Drink ¼ Marathon Rotterdam. The City Run Rotterdam and NN Kids Runs will then cost € 6.50.

Will I receive a medal?

After crossing the finish line, all participants will receive a medal as a souvenir of the event. You can also have your medal engraved with your name and finishing time.

Is there a time limit for the races?
  • NN Marathon Rotterdam: 5 hours and 30 minutes (21,1K within 2 hrs and 45 minutes, 28K within 3 hrs and 40 minutes)
  • AA Drink 1/4 Marathon Rotterdam: 1 hour and 20 minutes (6K within 50 minutes, 9K within 1 hour and 10 minutes)
  • City Run Rotterdam: 45 minutes

Participants finishing after the deadlines will no longer be included in the competition results and won't receive a medal.

Will my time be registered?

The MYLAPS BibTag system will be used to register your time in all divisions of the Marathon Rotterdam. Behind your running number (Bib) there is an electronic chip (Tag) and a plastic spacer. BibTag makes it very simple to register your times; the only thing you need to do is wear your race bib correctly.

Tips to guarantee good time-keeping

  • Make sure that your running number is displayed clearly on your chest. Do not cover it with a jacket or your hands when crossing the mats at the starting and finishing line. These mats pick up the signal from your BibTag. (Also be careful with operating your own stopwatch at the starting and finishing line).
  • Do not fold or crease your race bib. Certainly not where the Tag is located.
  • Use four pins at the corners of the bib, making sure that you do not pierce the Tag.
  • Do not remove the plastic spacer.
  • The BibTag uses different technology from the MYLAPS ChampionChip. This means that you cannot use your yellow or green MYLAPS ChampionChip during this event. However, you may leave your MYLAPS ChampionChip on your shoe, as this will not interfere with the BibTag system.
  • The Tags do not need to be collected after the race, so you can keep the bib (with Tag) as a souvenir or simply throw it away with normal waste (plastic).

What is the official time?
The gross time is the official time. This starts as soon as the starting shot has been fired and stops as soon as you cross the finish. The net time is the time that starts as soon as you cross the mat at the starting line and stops when you cross the finish. This net time is announced as an extra service.

And do not operate your own stopwatch, in the vicinity of your race bib.

What is medically advised?

Advice for the preparation and before the run:

1. If you have issues with your health, which results in high risk of heart / vascular disease, such as overweight, high blood pressure, high cholesterol, diabetes, earlier occurrences of heart /vascular disease, or it is prevalent in your family, or if you have injuries, we advise you to get yourself checked out by a sports medical specialist. In the Netherlands, that would be the Sport Medisch Adviesbureau (S.M.A.) or a sports policlinic. On the website you will find more information on check-ups, testing methods and a questionnaire (incl. A cardio vascular questionnaire) that you can fill in. After filling in the questionnaire you can determine whether it makes sense to have a cardio vascular check-up.

2. Clothing and weather:

  • Above 15 degrees and especially 20 degrees you must wear light ventilating clothing. Otherwise the body can't dispel the heat causing it to build up. (do not wear cotton; it retains moisture)
  • A thermal vest is best on the skin in cold weather (5 degrees and for slow runners 10 degrees). Wear a thin ventilated layer (no nylon) on top. A hat is recommended in wind and low wind chill factor.
  • Tie your laces well (dubble loop) and make sure they don't become loose during the race.

Note: The slower you run the more clothing you will need (except at around 20 degrees).  The body cools down quickly when walking.  The wind chill factor is determined by the wind and humidity.  For example: When the temperature is +10°C with average wind (wind-force 5) it will feel like +4.  However, if it is 5°C with average wind, it will feel like -4°C. In Rotterdam the afternoon temperature often falls by 5 or 6°C, which means among the slower runners we often see cold runners.

3. Make a training plan. This will of course depend on the event you are taking part in.

4. Run only on well-worn shoes (never new!) and socks and keep an eye on the road surface during your training. Change from left to right while running and go off road whenever possible. Please don't wear brand new shoes and socks for the race.

5. If you have or have had high temperature (>38 degrees Celsius) prior to the event (approximately two weeks), do not run.

Advice for directly before and after the run

1. How much you drink is dependent on the weather and how much you transpire (this is very personal). Drink up to 45 minutes before the start. The stop drinking and go to the toilet. Take a bottle (ca. 300 ml) with you to the starting pen and drink all of it 5-10 minutes before the start. This way you'll avoid having to go to the toilet during the race. Feeling thirsty is never a good measure. If you are not used to drinking, only drink water (100-200 ml) every 15 minutes. Drinks containing carbohydrates are also suitable. Make sure you consume about 70 grams of carbohydrates during the entire race. Bottles with measured amounts of sports drinks (that you carry with you in your belt) can help. If the weather is cool or if you are not a fast runner, consume energy drinks rather than solid food or fruit. The latter stays too long in the stomach. Remember: the difference in your weight before and after the race of 1 kg or more is the amount of liquid you have drunk too little. Try this out when you are training.
Click here for more information about drinking, individual liquid requirements and the drinking system during the ABN AMRO Marathon Rotterdam.

2. Listen to your body! If you don't feel well, stop running. The first signs of dehydration are: goose pimples on your chest and upper arms, shivers, pressure in the head, dizziness, later muscle cramp, vomiting and dry skin. These symptoms can quickly lead to disorientation and confusion. If you have experienced dehydration and/or high temperature then there is a high probability that you will experience it again, especially in warm weather. Do not run; there is no shame in dropping out!

3. If you have calf cramps run slowly or walk, do light stretches; don't stop but drink extra! Look out for dehydration.

4. Start slowly. Check your pace, every kilometre too fast at the beginning of the race can mean the loss of minutes per kilometre at the end of the race. Run at your own pace; avoid increasing your tempo or sprinting in the final kilometres.

5. STOP if you experience chest pain, abnormal shortness of breath or dizziness.

6. Keep an eye on the road surface and other situations around you.

7. Apply Vaseline to your nipples, thighs and other areas likely to chafe.

8. You are expected to carry medical information relating to illnesses (e.g. diabetes, medicines) with you -preferably written on the reverse of your bib number. Write also the telephone number of a person who can be contacted during the race. Also write your name, address and telephone number on the reverse of your bib number.

Advice for after the run

1.Drink a lot and warm down or cool down (depending on what you call it). Drink first and then eat a light meal (bread banana etc.)

2. Also in the days that follow walk regularly and drink more also consume more carbohydrates. Give yourself enough time to recover!

3. If the weather is cold, change your clothing immediately after the race and drink thee or broth. Do not drink any alcohol or coffee.

4. Directly after the finish it is sensible to drink lots and to consume enough carbohydrates. This will help you replenish the liquids and energy lost during the race. Recommended are sports drinks with carbohydrates, lots of water (>1/2 litre) and ripe bananas.

Urgent questions just before the race

If despite preparing well and reading the medical information you still have urgent questions, on the day before a running event, relating to training, injuries, nutrition etc. Please contact your local doctor.

We wish you all the best with your preparation!
