NOTE! Due to covid participants will be sent off one by one in the water, and your time will start when you pass the timing mat by the water. It is still advised to show up according to your start wave to prevent queues.
The start waves are mixed organized mainly by the competitors’ self-reported expected finish time. The start waves consist of 100-150 people each, with 15 minute intervals. Your start time will be listed on the start list and indicated on your BIB number and start envelope. Your swim cap color also indicates which starting group you belong in. It is your responsibility to start in the correct group. Change of groups can be requested at the latest one week before the race. Oslo Triathlon regrets if we cannot comply with your request.
Program for the day will be announced later on our web page.
Start wave assignments are published in the start list, itself published approximately 2 weeks before the competition day:
The transition area is for participants only and a valid race BIB is required to enter. At check-in, the bicycle brakes are checked and we control that the helmet is CE marked and sits correctly on the head, i.e., that the straps are sufficiently tightened. We really appreciate that all participants check this before check in to avoid unnecessary queuing.
Participants are assigned a spot in the transition area that are marked with your starting number. This space is at your disposal, however bags, backpacks etc. must be labeled with the luggage tag and stored in the designated area along the lower fence. Participants are encouraged to organise their equipment to assure a fast and smooth transition. The transition area will open be open from 07:00 AM and close 20 mins before start to ensure all participants can make it to the swim start in time. To reach the starting line, participants must cross a timing mat/point to register your timing chip. This registration is important to ensure that your time is correctly measured.
PLEASE NOTE! If you fail to check in your equipment in the transition area before the closing time race organisers reserve their right to revoke you access to start. To ensure everything runs smoothly for all participants, it is important to allow ample time to check in.
Prerace briefing is mandatory for all participants and will be held in the swim start area 15 minutes before each wave. Immediately after the prerace briefing there will be opportunity for a very brief warm-up in the water.

The cycle route leaves the transition zone, takes Sognsveien to the roundabout and onto Carl Kjelsen’s vei, then left up Maridalsveien. The route continues to Skar in Maridalen, where it turns and returns to Brekke. At Brekke, it turns again and starts the second round up to Skar, turn, and continue back along Maridalsveien, Carl Kjelsens vei and Sognsveien to the transition zone. You can freely choose your bike type. Helmet is mandatory. Drafting is not allowed: You must be at least 10 meters behind the bike in front or must pass other participants within a maximum of 20 seconds. Violation of the rules may result in disqualification.
