Everyone! All you need is to be born in 1999 or before... (18 years old in 2017). Parental consent required for minors.

Warning! When picking up race bibs, licenced runners must present their sports licence (FFA or FFTRI) showing that a medical certificate has been issued. Runners without a licence must present a medical certificate stating that they have no contra-indication to taking part in running competitions.

All registrations are done on the A.S.O. Challenges. Unlike many other registration sites, this one is straightforward. It takes no more than five minutes and you will immediately have confirmation of your registration. After creating your account (or after identifying yourself with your A.S.O. Challenges profile), all you need to do is fill in the form and pay (securely and online obviously).

If you want to join the elite or preferential starting area, register in the yellow starting area and send us evidence of your performance by email to We will then change your group!

Your registration includes:

  • Access to the Semi-Marathon Village, packed full of enthusiasm and surprises (oh yes!)
  • Free training organised by ability (great fun)
  • Registration for the race (more fun)
  • A (collector's item) T-shirt and running bag
  • Your exact time (which you can boast about - or not - after the race)
  • Your medal (because you have earned it, no matter what)
  • The status of the finisher (and that's priceless!)

The Challenge Entreprises is where employees in the same company get together to represent their company at the Fitbit Semi de Paris. Challenge Entreprises is also the opportunity for the intern to tell the Human Resources Director that they really want a permanent contract, for Fred (the accountant) to explain to Jean (his team member) that he is doing a great job, and for Alexandra to run alongside Tom, for whom she has a bit of a soft spot. In short, it is an excellent team-building tool!

Do you think your company could be interested? The presentation leaflet will be available at the end of the summer holidays.

Nothing could be easier: go and see your team leader and ask nicely for your advantage code. Then, all you need to do is register on the A.S.O. Challenges website. Then start training to make sure you clock up a good time for your company!

In order to pick up your race bib, you need to go to the Semi-Marathon Village at the Parc Floral de Paris, Bois de Vincennes

Route de la Pyramide - 75012 PARIS
Métro : Château de Vincennes (Ligne 1)
Bus : 112

Things to take with you:

  • Your invitation (available on A.S.O. Challenges a few days before the race)
  • Your valid medical certificate (once again, we recommend you use our model
  • A piece of ID (too bad if your photo isn't the most flattering!)

The bib must be pinned to your chest throughout the race (using the pins provided, don't worry, you don't need to go to a haberdashery shop!). It mustn't be covered or modified. Anyone not wearing the bib will be disqualified from the race. Yes, it's tough but that's how it is.

Watch out: No bibs will be given out on the Sunday morning, the day of the race!

You're asking all the right questions!

Where? Au Village du Semi situé au Parc Floral de Paris
Are there metros? Yes! Line 1 (Château de Vincennes) or even the bus (line 112)
When? Friday 3rd March from 10am to 7.30pm or Saturday 4th March from 9am to 7.30pm

Watch out: No bibs will be given out on the Sunday morning, the day of the race!

Oh yes! Without a valid medical certificate mentioning “no counter indication to taking part in athletics competitions” or “no counter indication to taking part in running competitions”, you won't be able to run! Check out our medical certificate page to be sure that yours has been provided correctly. Even better, to avoid errors, we recommend that you use our model certificate which is available here.

That's easy, we'll send a carrier pigeon to pick it up! Only joking, no certificates will be sent out by pigeon or by post. You must provide your medical certificate when you pick up your race bib at the Village on 4th or 5th March (no bibs will be given out on race day). Watch out! If you don't have a certificate or it doesn't comply with the rules, you won't get your race bib! So, pay close attention to the criteria.

Of course you do! Just like you, we don't want to get into trouble with your parents. So hand in your parental consent form at the Village in order to pick up your race bib. You can download it here.

The official start time is 9am but it's better if everyone doesn't set off at the same time on the race route. For the comfort of all involved, each starting area has its own start time.

We advise you to get to your starting area at least 30 minutes before your start time.

Right next to the Esplanade du Château de Vincennes.

  • Where? At the Village in the Parc Floral de Paris in the Bois de Vincennes - Route de la Pyramide - 75012 Paris
  • How do I get there? By metro, line 1 - Château de Vincennes or on the 112 bus
  • When? On Friday 3rd March from 10am to 7.30pm and on Saturday 4th March from 9am to 7.30pm

Watch out: No bibs will be given out on the Sunday morning, the day of the race! 

When you pick up your race bib, we will also give you a timing chip which takes the form of a strip stuck behind each bib. Long live technology! This chip will be automatically started when you cross the start line and will check your regularity throughout the route at various points (every 5km in fact). For example, a participant who doesn't take the right route can't be ranked at the end

For your chip to be detected by the timing mats throughout the route, make sure that you:

  • Don't fold your bib
  • Don't crease your bib
  • Don't unstick the strips
  • Don't let children draw on them either
  • And if you are wearing a top over your bib, remember to unzip it when you run over the mats.

We will make sure that you get all the sustenance you need to get across the finish line! Refreshments will be organised every 5km. You can grab some water, dried fruit, fresh fruit and sugar.

No, there are no changing rooms. You might need to walk across Paris in your fluorescent outfit, but for once, this is acceptable. But there will be left luggage facilities at the Esplanade du Château de Vincennes. You can leave your (closed) bag there and pick it up after the race upon presentation of your bib.

You can leave your bag for free at the left luggage facilities at the Esplanade du Château de Vincennes, so you can run with a clear head and empty pockets. You pick it up after the race upon presentation of your bib.

You will find toilets at the Esplanade du Château de Vincennes, near the left luggage facilities and alongside the starting areas. If you need to go during the race, well, you'll just have to run faster!

Of course! In each starting area, pacemakers will be there to help you meet your goals. Just like cabaret dancers, they are easy to spot: they will be wearing streamers in the colours of your starting area!

Your results will be available on the A.S.O. Challenges website from the afternoon of Sunday 5th March. You can download a certificate on the same site and find photos and videos of the race. All you'll need to do is share them on your social networks to show what you were doing while everyone else was lazing in bed!

Of course! We don't want to put you under any pressure (promise!), but it has to be said that we want you to run a good time (a little bit of pressure never did any harm)!


  • Individual ranking including all runners.


  • A ranking per team based on the number of kilometres run.
  • Ranking based on average performance of the whole team's time.

The finisher's medal will be given to you at the finish line, at the Esplanade du Château de Vincennes. Almost as soon as you arrive, you can show off your winnings!

If you're not scared to see what you look like during the race, you can find all your photos on the website

Yes! Runners can enjoy post-race treatments from osteopaths at the finish area, at the Esplanade du Château de Vincennes. They will certainly have earned them!

Check out the list of participants.

Don't panic! Hundreds of cheerful, helpful volunteers will be available throughout the event. We will make sure they are everywhere! In particular, you can find them when you pick up your race bib, at the refreshment stations, throughout the race and at the finish line. They are there for you, so even if you are totally concentrated on your time and your stride, be nice back to them, give them a smile and thank them for their encouragement with a nod.

With pleasure! We'd be mad to refuse enthusiastic helpers - maybe you can encourage others to help too? Bring your good humour and generous nature and join our hundreds of volunteers to help make this event run smoothly. For more info, go to our special volunteers page.
