Where can I access toilets?

In all start areas.

Remember to bring some toilet paper in your pocket.

If you have to use the forest during the race,  you must cover with soil when you are done. Do not use gardens!


80km: Toilet at second, third and fourth support  station. And 10km before finish.

50 km at first and second support station. And 10km before finish.

31 km at first support station. And 10km before finish.

21 km and Walk at 10km before finish.

10 km no toilets before finish.

Toaletter på Vippa i mål.


Support is only allowed at the drink/food stations, 

Many ask if it is allowed to change shoes during the race.

As long as you carry the shoes yourself in your bag, you can change whenever and wherever you want. You have to carry the shoes all the way.
If you want friends to hand ove shoesr, it is only allowed at the drink/food stations. It is only legal to have any form of support within the drink/food stations.

No drop bag.

Why do you ask for estimated time in the registration?

In order to make a flow analyse, for security reasons. We will get an idea when we can expect big groups at the finisher area, etc. 

Will there be photos from the race and of all the participants?

Yes, at six nice spots along the trail. Remember to have your bib in front,  otherwise it will not be possible for you to search for your photos.

The photos are taken by Sportograf, and they will be available after the race. 

In addition to those photos, we have our own video team, and they have a good plan for the day . Plus other hired photographers at start and finish who will catch the good vibe. :)

Lost & found

When we clear the finisher area from 8pm we put forgotten belongings inside Vippa. The big building with grafitti. 

You have to pick up yourself and you have to check yourself Vippa´s opening hours. 

When you pick up, refer to Ecotrail Oslo, and describe your belonings. 

Why can't I pick up bib at start area?

There are various and good reasons for that.

As for 2024 we have Print On Demand. Meaning that these 3 machines can only be served at one location. 
The only exception is for 80KM: Unclaimed bibs will be printed Friday night and transported to start area on race day. 

Bib distribution same week as race day:  Address is Anton Sport, Bogstadveien 2. 
See more info via menu on this web site, click "Bib distribution" 


What shoes do you recommend?

It depends on the distance you have signed up for.

And the weather conditions, and not to mention the ground conditons! 


If you're going to run 10km, you don't need mountain shoes. The 10K has gravel and asphalt. All of the Ecotrail Oslo distances ends on asphalt the last 5km. 

Otherwise, 80km, 50km, 31km and 21km have a mixture of dirt road, asphalt, trail and  technical. If it is dry, it is perfectly fine to run with a "road oriented" shoe.

If it is wet, a sole that provides grip is recommended. 

We have a shoe partner and they are called Hoka. So all text below goes under "advertisement".
But the two guys who work with the Hoka shoes in Norway are excellent runners themselves (and incidentally winners of our 50, 31 and 21 km)

They say that their recommendations below will actually apply to most distances. But if the conditions are dry, you can perhaps allow yourself to choose a bit more road-oriented, especially at 10km.


Tecton X 2 / Tecton X is their top recommendation. And then they add a couple of other options that might be relevant:

Tecton X 2 / Tecton X
Here you get a shoe packed with features that are perfect for the Ecotrail. A well-cushioned but responsive midsole will take good care of your legs whether you run long or a little shorter. The sole has 4 mm Vibram Megagrip studs that ensure good grip on the trails. In addition, this shoe has carbon plates, which will both protect and give you a very good response in the stride. The upper provides good foot support and there is plenty of room for the toes at the front of the last. This shoe was used by the winners of both the 50km and 31km last year, so no doubt this is a good choice for the Ecotrail. You can buy this shoe at Anton Sport during the start number distribution!

Mafate Speed 4
Well-cushioned trail shoe with a responsive midsole. With this shoe, you are guaranteed a very good grip during the race, and can be a sensible choice if the conditions are wet/slippery. A robust shoe that will take good care of your legs if you run one of the longer distances!

Speedgoat 5
Solid and well-cushioned all-terrain shoe with very good grip. The Speedgoat is a real workhorse in the terrain, and will be a good choice for you who put comfort and stability on the trail first and foremost. The shoe is so well cushioned that it will cope well with the transport stage for the last few kilometers on asphalt, even if it is a mountain shoe.

Torrent 3
Do you want a slightly lower shoe and more contact with the ground? Then Torrent 3 is a good choice! Here we have a light and flexible shoe with a responsive midsole and you get good contact with the ground on the trail. Perhaps particularly relevant for the slightly shorter distances.



Why can't I ask for a refund or transfer to next year or to another Ecotrail event?

The registration is binding.
However, you can give away/sell your registration to another person on your behalf. In order to do this, you have to change the email in your profile. The other person must then ask for a new password with that email and type correct info (name, adress etc). Payment´s organized beween the two of you. See more in FAQ overview.

It is not possible to transfer to next year or to a another Ecotrail event as these have seperated registration and economy.

Absolutely not.

Sorry, we do not have this service.  You should try poles at a retailer, get the correct height and make sure you buy a pair you feel comfortable walking with. 

Will you mark the trail with flagging tape?

Yes, yellow/red flagging tape all the way +  white paint on the ground at crossings. In addition to this there will be signs at critical points. (New of 2019)

We have tracked them with several devices. It will never be accurate, least not through the forests. The longer the distance, the more variations on participant´s devices...Normally 0,5 up to 3 km in difference for the 80km distance. 

Do I need a medical certificate for Ecotrail Oslo?

No, you don´t need one in Oslo. You participate at your own risk!
