Barnas Maraton

Kids Marathon

Bring your kids for a fun and active day at Kontraskjæret!

It is not only adults that get to challenge themselves during BMW Oslo Maraton. On Kontraskjæret next to Rådhusplassen we arrange activities and races for the kids, together with SK Vidar and Læringsverkstedet Idrettsbarnehagen.


A 100 metre Mini Marathon runningtrack will be available for children aged 0 – 4.

For children aged 5 – 12 there will be a Kids Marathon which is split up into 500 metre runningtrack for those aged 5 -9, and a 1000 metre runningtrack for those aged 10 – 12.

In addition to the runs there are other activitiers where kids can play and have fun. Here are some of the activities we had in 2019:

Kids Marathon: 150 NOK

A bib number and t-shirt are included in the price, and they receive a medalje when they cross the finish line of the race.

Maximum age for participants is 12 years old.


Franzefoss monsters will also make an appearance, teaching kids about the environment and recycling!



With the exception of the Mini Marathon, parents are not allowed to run with their children. In the Family group at 12.45 parents HAVE to run together with their children. Designated officials will both run with the children and be plassed around the runningtrack. The entire runningtrack will be fenced in for safety.

Due to safety concerns it will only be possible to pick up children at the entrance/exit to the runningtrack. Children will be let out one at a time. Children who cannot find their parent by the exit will be taken care off by an official from Læringsverkstedet Idrettsbarnehagen.


When picking up the bib number you will recieve two bracelets. One for your child and one for you. Your name and contact details must be written down on these. Ved henting av startnummer vil dere få to armbånd med navnelapp, en til barnet og en til foresatte. Her skal navn på foresatte og kontaktinformasjon skrives på. Parents/guardians must show their bracelet when picking up their child at the finish area.

Bib number pick up

In the week before the event you will receive a start card to your registered email address. To pick up your bib number you must bring your start card  together with a valid form of ID.

If you are picking up a start number on behalf of someone else, you will have to show their start card and a valid copy of their ID.


On Thursday and Friday you can pick up your Kids Marathon bib number at the “Barnas Maraton” stand in Expo at Rådhusplassen.

On Saturday bib numbers can be be picked up at Kontraskjæret. There will be a tent marked “bib number pick up”.
