A unique running event around six lakes in Uppsala, offering 42 km marathon, 21 km half marathon, 10.3 km, and 5.5 km options. The race takes place on trails and small forest roads, with a swim in the lakes as a popular finish.
Water, energy drink, bananas, sweets, and a post-race swim in the lakes. A light café and food options are available at the start/finish (Fjällnora).
Pacers are listed on the respective distance pages. Marathon starts first at 10:00, followed by half marathon at 10:30, 10 km at 11:00, and 5 km at 11:30. Pacers help keep runners on track and maintain target times per start wave.

The best alternative is to visit Resecentrum (Uppsala central station) on Thursday or Friday before the race between 11:00-19:00. We have a stand just outside. Link to Google maps. Please observe that this is on the west side of the tracks. (The bus on race day leaves on the east side) Another option is to simply show up in Fjällnora at least 40 minutes before and we will give you your race number.
Yes, when registering you can choose one bus to Fjällnora. That helps us planning, but it is no big deal if you change. On the way back we have free transfer buses every half hour or so, no reservation needed. Please tell the crew if you have a tight schedule and need to be prioritized if the buses get full.
We have plenty of aid stations, every 3 km or so. They are manned and have water, sports drink, banans, sweets etc. Even the 5 km-course has an aid station. Exception: The marathon course has three unmanned aid stations with just water. This is a cup free race. This means that you bring a cup or bottle and fill it at the stations. If you don’t have any yourself you will get a Hydrapouch for free. You just come to the aid station, fill with water or sports drink and continue.
Roughly every third kilometer. At the 5 km course that means just one aid station, on the marathon there will be 13. Here is a map of all aid stations (2024).
You will find water, sports drink, fruit, sweets. The brand of the sports drink is Umara with lemon taste. On the longer distances there are gels and energy bars from Umara, Coca-cola, and coffee at the end of the race.
Everybody who wants receive a smart multi-use silicon cup, please re-use if you have one already. You just refill it in the aid station and drink. You can drink as you run, but please note – it is not a bottle.
Your ordinary running shoes will be fine. If you prefer trail shoes that will work too, but don’t expect to run faster – it’s only on the 5 km race that you can expect to run faster with trail shoes. On the marathon, half marathon and 10 km race the majority of the course is on gravel or flat paths – just a few kilometers are on more technical trails.
We have not placed toilets along the route, but there are some possibilities.: – Borgis/Borgardalsbadet (Marathon 4.5 km), simple toilet near the beach – Funbo kyrka: (Marathon 24 km), WC near the church – Norredatorp (Marathon 37 km or half marathon 15.5 km): We may have access to a WC near the buildings, if not there is a simple toilet at Eda lägergård, 500 m further along the route. You can always ask volunteers on aid stations.
The earlier you register the better price you get. Registration online closes about two weeks before race day, earlier if any distance gets full. It may be possible to register on race day for another additional fee. But there is no guarantee that there are tickets left. We generally have plenty of space, but 10 days before the race we print the race numbers (bibs). This may limit the number of participants. So, please register early – that will help us to arrange the race in the best way.
Yes. About every second participant comes from abroad. Around 15 minutes before each start there will be a short pre-race information in English. Almost everybody in the staff speaks English.
We provide a free direct bus from Uppsala. Or you can go with your own car, it is around 15 km east of Uppsala (Address: (Fjällnora, Uppsala”). Or bike, walk, run or come by boat from Marielund. Please note that the regular bus from Uppsala, 809, stops about 3 km from Fjällnora. It is actually possible to take the steam train Lennakatten combined with their bus to Fjällnora, but it arrive too late for most participants.
It’s a mix. There are no mountains, but small hills. The shortest course (5.5 km) is mainly forest, the others are dominated by gravel with some asphalt and track.
All finishers get a wooden medal “6 Sjöar” produced in Sweden. We are environmental concerned, so there is more focus on running than merchandise. You will find personal diplomas as PDF on your result page to be printed. T-shirts are sold as an add-on on registration, but may also be possible to buy after the race – but please note that there are a limited number.
Timekeeping is carried out by Neptron. On your bib number there is a tiny disposable chip. Time is automatically registered as you cross the finish line and immediately available on the results page.
No, as a race on mixed surfaces we cannot get an official measurement of the distance. The 10.5 race can turn out to be 10.3 or 10.8 depending on which the device you use to measure. However, we make the marathon slightly longer than the official 42 195 km –just to be sure. Your device will probably say something like 42.5 to 43 km when finishing.
Yes, just send a message to info@6sjoar.se. If you change late (the last day) your result may not show in the lists. If you choose a loger distance you will pay the additional cost.
A few dogs are allowed. Please contact info@6sjoar.se if you plan to bringing a dog or if you are disturbed by dogs. We will keep a dialogue to avoid problems.
The non-governmental organisation 6 sjöar takes care of the race. The only aim is to organize the event. So, revenues will be used to improve the race. Volunteers do most of the work, even the race organisers are volunteers.
Yes! 5.5 and 10.5 km is possible to walk all the way. The longer distances are possible to walk at least half the distance.
No hurry. Around 16:00 the last aid stations will close. But we will keep som service open until last person finishes. The previous years the last runner came in around 17:00 (7 hours for the marathon). If you plan to run slower than 6 hours for the marathon, please tell us beforehand. But we will stay until the last runner arrives.
You are welcome, but please note: No prize money and no special medals!
The routes are well marked with ribbons and signs, so don’t worry. On the two shorter ones you will encircle just one lake. For the marathon and half marathon, you may like to have a look on the map – we will provide you with one. Bring a mobile phone just in case.
Fjällnora is a popular beach in summer. We recommend a swim instead of a shower (please tell us if you need a hot shower, it is possible but is provided as an extra service). There are changing rooms by the beach.
It is open daily 10:00-16:00. We have asked Fjällnora to have it open 09:00-17:00 on race day.
Yes, you can store your luggage in the start area. There is a tent with staff, and they will write your race number on a piece of sticky tape and put on your luggage.
It is possible to arrange, please contact info@6sjoar.se. Depending on the child’s age and need we may charge you.
