British Athletics Championships: Break 10 seconds to win - Gemili

Adam Gemili says the British Championships in Birmingham will be a "great spectacle"

Britain's Adam Gemili believes his fellow sprinters will need to break the 10-second barrier to win the 100m at this weekend's British Championships.

The men's 100m final at the Championships - which double up as trials for the European Championships in August - takes place on Sunday.

And Gemili, who will only be running the 200m in Birmingham, predicts a "great spectacle".

"You're going to have to run really quick to make the team," he added.

Speaking to BBC Radio 5 live, the 20-year-old continued: "A lot of guys are going to be raring to go and it's going to be very competitive - a race not to miss."

Gemili has decided to focus solely on the 200m at the European Championships so misses the 100m this week, while James Dasaolu, who ran a phenomenal 9.91 seconds last year at the same venue, will also not run.

Dasaolu, who was scheduled to make his comeback at the championships this weekend, has been given special dispensation to miss the event after struggling with injury for most of the year.

The 26-year-old Londoner said the trials had come "a week too early" and will instead attempt to prove he is worthy of a place in the European Championships team at the Diamond League in Lausanne next Thursday and the Glasgow Grand Prix in a fortnight.

"The best opportunity I have to achieve the standard is at those two races," Dasaolu said, "and I am really grateful that the team supporting me are helping us make these decisions."

World 60m Indoor champion Richard Kilty, 24, and 20-year-old Chijindu Ujah, the fifth-fastest man in the world this year after clocking 9.96 seconds last month, will be among the favourites for the national title.

The pair will also have to contend with Dwain Chambers who, at 36, will attempt to win a fifth straight British 100m title.

Elsewhere, Olympic champion Greg Rutherford is not competing in the long jump, so rival Chris Tomlinson will attempt to take the British title.

Heptathlete Katarina Johnson-Thompson, 21, the world indoor long jump silver medallist, will compete in both the long jump and high jump and will go head-to-head with fellow heptathlete Morgan Lake.

The women's 800m will feature promising teenager Jessica Judd, who is the only competitor to run under two minutes this year, Lynsey Sharp and 2009 world bronze medallist Jenny Meadows.

In the women's 1500m Hannah England will attempt to stave off the challenge of Laura Weightman and Laura Muir - currently third and fourth respectively in the European standings - to clinch her fourth 1500m title.
