When is the NN Marathon Rotterdam?
The organisation has scheduled the 40th NN Marathon Rotterdam, due to COVID-19. The NN Marathon Rotterdam is now scheduled to take place on 23th and 24th of October 2021.


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.


Do I get a medal?
All participants will receive a medal as a reminder of the event after passing the finish line. In addition, you can have this medal engraved with your name and finish time.

Medal engraving

Can I have my medal engraved? 
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.


Where can I find my results?
The results will be published on this page afterwards. You will also receive the link to the results page by e-mail after the event. Note: the gross time is the official time. Do you have a question or remark about your results? Send an e-mail to Mylaps Event Timing based on your start number and any times you have clocked yourself.

Time registration

Is there a time registration?
Only at all parts of the Marathon Eindhoven 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.

Time limits

What are the time limits?

  • 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.



Does the NN Marathon Rotterdam supports a charity?
Yes. This anniversary year the NN Marathon Rotterdam has chosen to support The Dutch Cancer Society (KWF Kankerbestrijding). The organisation asks all participants to contribute to revolutionary cancer research.

What volunteer tasks are there and how can I sign up?

Medical advice

What is medically advised?
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!
