James Dasaolu, James Ellington and Chijindu Ujah run sub-10 seconds at the British Championships

James Dasaolu ran 9.93 seconds in winning the men's 100

James Dasaolu came out on top of three sprinters to break 10 seconds in the final of the 100m at the British Championships in Birmingham.

Dasaolu claimed gold, and a place in the team for the Olympic Games in Rio in August, by winning the title in 9.93 seconds, albeit his run coming with an illegal tailwind of three metres per second.

Joining Dasaolu on the plane to Brazil is James Ellington, who took the silver medal in 9.96 seconds, while Chijindu Ujah looks set to go as well after finishing third in 9.97.

European champion Dasaolu was returning to form after a year that saw him fail to make it out of the heats in the World Championships, lose his National Lottery funding and suffer disqualification for a false start at the World Indoors.

"Seven guys on the line had the Olympic qualifying standard, so I knew that if I didn't finish top two, top three, my dream of going to Rio in the 100m was in jeopardy," said Dasaolu, who recorded his personal best of 9.91 on the same track three years ago.

"I'm pretty sure I ran that sub-10 in the same lane, lane four, so going in I thought, 'Lane four again, it's meant to be'. Top three under 10 in the same race bodes well for the relay and for sprinting as a whole."

Asha Philip was all smiles after sealing her Olympic place with victory in the women's 100

There was something of a surprise in the women's 100 where favourite Desiree Henry was left sweating on a discretionary Olympic place after finishing third.

Henry's time of 11.26 seconds was only good enough to finish behind champion Asha Philip (11.17) and teenager Daryll Neita, who sealed qualification with a run of 11.24.

Her hopes will most likely rest on Dina Asher-Smith deciding to concentrate on the 200m in Rio.

In other events to conclude on Saturday, sisters Tiffany Porter and Cindy Ofili booked their Rio spots with a one-two finish in the 100m hurdles.

Also booking their Olympic spots were youngster Morgan Lake in the high jump, although she still hopes to qualify in the heptathlon, pole-vaulter Holly Bradshaw, Sophie Hitchon in the hammer and Andrew Butchart and Tom Farrell in the 5,000m.
