Caitlyn Bobb booked her place at the World Athletics Under-20 Championships after meeting the qualifying standards in the 400 metres.

Competing in the Maryland State High School Championships, Bobb enjoyed an impressive outing two weekends ago, claiming a rare sprint treble — in the 100, 200 and 400.

It was her winning time of 53.72sec in the latter — easily inside the qualifying standard of 54.85 — which proved enough to see her seal her spot at the Under-20 Worlds in Nairobi, Kenya, from August 17 to 22.

Bobb was also agonisingly close to qualifying in the 200, with her time of 24.37, falling just two hundredths of a second of the 24.35 standard.

The daughter of 1992 Olympian Dawnette Douglas, herself a sprinter, also competed at the East Coast Track and Field Championships in New Jersey where she claimed an impressive second-place finish in the 400. She clocked 54.30, narrowly behind the winning time 54.20.

Bobb is scheduled to compete on home soil for the first time as part of the national championships on July 10.

There was also a strong performance from compatriot Nathan Armstrong, who qualified for the Nike High School Nationals with victory in the 800 at the East Coast Championships on Thursday.

Armstrong’s winning time of 1min 54.38sec was not only good enough for qualification but also proved a school record. He is also due to be competing in the national championships, where he will take on Carifta Games gold medal-winner Nirobi Mills-Smith and Sancho Smith.

The latter pair faced off on island in a Bermuda National Athletics Association meet last weekend with Mills-Smith narrowly prevailing, crossing the line in a winning time of 1:57.71 just ahead of Smith in 1:57.73.

Both will be aiming to improve on those times as they aim to hit the qualification time of 1:50.80 and join Bobb on the flight to Kenya ahead of the August 2 deadline.
