Swimmers Thom de Boer and Valerie van Roon (both left in the photo) have assured themselves of participating in the Olympic Games in the 50 meter freestyle on Thursday.

They met the limit at the Rotterdam Qualification Meet (RQM) and belong to the two fastest times.

De Boer had already tightened the Dutch record to 21.74 seconds in the morning.

With his time in the final (21.75), the 28-year-old North Hollander remained well below the Olympic limit of 21.91 in the evening.

Nyls Korstanje swam to second place, but remained above the limit with 21.98.

As a result, De Boer and Jesse Puts, who finished twelfth at the World Cup in 21.91 last year, are qualified for the Tokyo Games.

In the women, Ranomi Kromowidjojo was the fastest in the 50 meters free in 24.38.

She was well below the Olympic limit of 24.77 at the World Cup last year with 24.35.

In Rotterdam, Van Roon remained below that target time with 24.63.

The 22-year-old Van Roon was faster than the absent Femke Heemskerk, who went below the limit in 24.71 last year, but is now in quarantine because of a positive corona test from her husband.

Van Roon can now, together with Kromowidjojo, come out on the 50 free in Tokyo.

In Rotterdam, the Dutch top swimmers will hunt for limits for next year's Olympic Games in Tokyo until Sunday.

You can also earn tickets in Rotterdam for the European Long Track Championships, which will be held in Budapest in May 2021.
