The pole vault competition in the square in Lausanne on Wednesday ended in the dark, as it dragged on.

But Armand Duplantis managed to jump 6.07, the second best jump of all time and of course both personal best and Swedish record.

Less than 48 hours later, he should be ready again, in Brussels.

He himself is not worried:

- I may try to recover until then.

I think something can happen there too, even if you can never really know.

I get to do what I have to do, says Duplantis.

Klüft: "There is nothing to save"

SVT broadcasts the prestigious Diamond League gala in Belgium and SVT expert Carolina Klüft believes in Duplantis:

- The starting field is smaller and I think he will be alone at the higher altitudes.

That means less hope and can be nice if he is a little tired, she says.

- Right now there are many competitions in a short time but Duplantis likes to compete and there is nothing to save on.

Do not believe in the new form of competition

However, Carolina Klüft is personally hesitant about the entertainment value in the organizers' investment in two longer special races.

Both men and women should try to run as far as possible in 60 minutes.

That means more than two miles on the running tracks.

- I do not mind new concepts to create interest, but personally I do not think it will be so exciting to run so far on the track.

It's not like a marathon or cross-country race.

I'm skeptical of the entertainment value, but we can only hope that it will be worth seeing.

Swedish participants in the one-hour races are Sarah Lahti, David Nilsson and Emil Millan de la Oliva.

In the ladies' height, Erika Kinsey and Sofie Skoog are registered.

SVT Broadcasts from Brussels starting at 20.00, on SVT1, Friday night.
