Jari will on 10th of June begin the world’s longest unsupported swim from Stockholm, Sweden 500 km to Helsinki, Finland. A 37 day long extreme adventure where he will be averaging 13,7 km day.
In order to complete his really impressive challenge he will need to bring two 55 Liter bags with a total weight of 46 kg. Packed with tent, watermaker, dry food to cover all meals, swim gear and other essential gear.
The bags will then be placed on top of a Ruckraft in order to glide as smooth as possible behind Jari while swimming where each raft is attached with a bungy cord with safe distance behind him in heavy seas.
The bag float fully packed with Jari on top by itself and could be attached to each other as a raft in case of an emergency.
Jari is currenlty living down in Allicante, Spain where he’s training daily be filling up big jugs of water to get proper weight in the bags.
This is not the first adventure for Jari as he last summer swam 328km along the east coast of Sweden, Oaxen to Öregrund. A 32 day long adventure where Jari had to take one day off due to back problems.
