Vasaloppet, Vansbrosimningen, Vätternrundan and Lidingöloppet. It will be a total of 438 kilometers in 24 hours.

To SVT's and Jonatan's knowledge, no one has previously met the challenge, at least not without flying a helicopter between the routes. Jonas Colting from Borås tried in 2004 but finished in 25 hours and 17 minutes. Several other people have completed the distances and steps, but not in the traditional places of the races.

Jonatan will complete all races on the original tracks, except for a certain correction of the Vasaloppet track, which he rides on roller skis on the asphalt road next to the tracks.

To help him, he has his partner and father, who follows by car. They must make sure that he gets something to eat and that the equipment lasts. And, of course, be drivers between races.

Jonatan Hugemark is investing in a professional career in triathlon and what he is most worried about is not that the body will fail - but that the equipment breaks down.

See how he plans the four races in the clip above.
