Tyson Gay eased through his first 100-meter qualifying heat in the U.S. Olympic trials Saturday, winning in 10 seconds flat.

Gay, mending from a hip injury that kept him out of action for most of the past year, matched the time he ran in his return in New York earlier this month. That race was into a headwind. This time, on a rainy day in Eugene, he had a slight tailwind.

Justin Gatlin, the 2004 Olympic champion, won his heat in 9.90 seconds, keeping alive his bid to return to the Olympics after missing 2008 because of a doping ban.

Again in sharp contrast to Chambers, young Gemili behaved with elegance and class. Finishing second in 10.29, with his own A standard already secure, he thanked the crowd for their support and virtually squashed the notion that he might consider himself unready for Olympic competition.

Of course, he would discuss things with his coach, but said: ‘Everyone wants to go to the Olympics.’

For his part, Chambers will attempt to land the qualifying time in the remaining days before the Games. ‘I have a chance to get it at the Europeans in Helsinki next week, so that is the next step’, he said. ‘The pressure of trials is the hardest part and I’m glad it’s over.’

Perhaps the most positive outcome of the trials was the evidence that Jessica Ennis is at the top of her game. She has had to live with her billing as the poster girl of the London Games and all the signs suggest she is carrying the burden with easeful grace.

On Saturday, Ennis was an enduring revelation. She soared over the high jump with 1.89m and a curiously dramatic absence of effort.

Then, still more impressively, she snapped across the high hurdles in head-to-head combat with British team captain Tiffany Porter. Ennis was impeccable, Porter clipped a hurdle with a trailing leg and Ennis’s time of 12.92 spoke encouraging volumes for her hopes of the Olympic heptathlon title.

Dwain Chambers exploded with emotion as he crossed the finish line to win the British 100 metres title and keep his Olympic dream alive. Leaping around the track in unbridled celebration, the 34-year-old who has been struggling for form all season let out a primeval roar to show just how much the victory meant.

Having struggled in the heats and the semi-finals, Chambers ran a season's best time of 10.25sec – still slower than the Olympic 'A' qualifying standard of 10.18 he needs to secure automatic qualification for the Games but enough to show the selectors that Britain's only current sprinter to have run under 10 seconds cannot yet be written off.

"That's the most scared I've been in a long time," Chambers said, his shoulders still peppered with tiny lumps of asphalt from rolling around on the track. "I didn't even think I was going to finish in the top three. That's how bad it got.

"When you don't run well your mind starts to play games and that's what was happening. In my mind I said, 'If you don't run well it's over for you'. I just had to think about the times when I wasn't having a good time, I had to draw on that."

It’s a lot to tackle for a runner who’s still fighting a baffling illness.

Then again, Richards-Ross prefers a swift pace, whether it’s on the track or in life.

“That’s how my brain operates. I need a million things going on at one time so I can do one thing well,” said the 27-year-old Richards-Ross, who will run in the first round of the 400 on Friday night.

After two injury-plagued and inconsistent seasons, Richards-Ross is rounding back into her top form again, the one that led to a 2009 world title in the 400. That crown meant a lot to her, simply because it showed Richards-Ross she could indeed win on the biggest of stages.

Before that race, she had a resume filled with narrow misses at major meets.

At the top of the list was her performance at the 2008 Beijing Games. She was the favorite entering the 400, but faltered down the stretch and faded to third place.

Heartbroken, she dissolved into tears immediately after the race.

She hasn’t watched many replays of that race, just enough to remember the sting of the moment.

“I can remember the feeling of crossing the finish line and being so disappointed,” Richards-Ross said. “I learned a lot from that — about being patient, not just in race, but throughout the season. I’m definitely using that to prepare myself for this year. I know I have a better performance in me than in 2008.”

So far, she’s off to a flying start. Richards-Ross has the top time this season in the 400 when she finished in 49.39 seconds at the Prefontaine Classic on the famed Hayward Field track earlier this month.
