KINGSTON, Jamaica—Demisha Roswell has been promising and she finally delivered, capturing her first Jamaican 100m hurdles title in convincing fashion, turning back Megan Simmonds and company at the National Junior and Senior Championship on Sunday.

Roswell has been knocking at the door over the years, and this year, it came as no surprise to see the fantastic form she displayed in early 2026.

Roswell won in a personal best 12.40 seconds ahead of Megan Simmonds in 12.47 and Kerrica Hill in 12.67. Janela Spencer of Ohio State University was fourth in 12.74.

Despite finishing fourth in 2022 and being a reserve for the World Championship team, Roswell has been relatively unknown to the Jamaican public.

“I’ve been prepared. I knew from the season started I’ve been running consistently. So, I knew I was going to run fast,” said Roswell.

In February 2026, Roswell won the women’s 60m hurdles at the Charlie Thomas Invitational in Texas ahead of Jaiya Covington, running 8.09 seconds in the final, having broken the meet record in the preliminary round with a run of 8.02 seconds.

Then on June 6th, she won in 12.53 seconds ahead of fellow Jamaican Ackera Nugent and Rayniah Jones for the 100m hurdles at the 2026 USATF Lone Star Grand Prix in College Station, Texas.

Her latest performance, her personal best of 12.40 seconds, has now moved her to joint-fifth fastest on the Jamaican all-time list alongside Janeek Brown.

“I’ve seen it coming since LA (Los Angeles), but I still ran 12.7. But I knew, I was like ‘I’m going to run 12.4’. I felt it, I knew it. But it just went and today is the day that I run it,” Roswell explained.

Now Jamaica’s champion, Roswell said she will be looking forward to representing her country at the Commonwealth Games in August.
