Women's 100m: Carmelita Jeter returns to the track where, three weeks ago, she won the Pre Classic in 10.70 - tied for the seventh-fastest time ever, it is the fastest time so far in the world this year. With two World Outdoor bronze medals to her credit, Jeter dreams of challenging for gold on the world stage this year but will first have to make the American team. There to challenge her in Oregon will be Marshevet Myers who finished as the runner-up to Jeter at the Pre Classic in a personal best 10.86. Not to be overlooked is 2005 World champion and big-meet performer Lauryn Williams. The wild card in this race is 2010 USA Outdoor champion Allyson Felix. The three-time World Outdoor 200m champion has a bye into the World 200m race and has not yet decided what she will run at nationals.
Women's 100m hurdles: Heading into this season, Lolo Jones would have been the first choice to win nationals, but following some iffy performances this years' title looks to be a race between defending Olympic champion Dawn Harper and current world leader Kellie Wells. Harper has had a strong start to 2011, winning three of her four races so far while Wells let the world know she was a legit contender with her windy 12.35 in Gainesville earlier this season. Also watch for Pre Classic winner Danielle Carruthers and three-time World Outdoor team member Ginnie Crawford.
Women's high jump: Just twelve weeks after giving birth to her second child, Chaunte Lowe will be back out on the infield to compete for her fifth national outdoor title. At last year's national championships, Lowe broke her own American record in winning the high jump with a 2.05m/6-8.75 clearance before placing second in the long jump. This year Lowe just hopes to make her third world team. To do that, she will need to finish in the top three and jump the ‘A' standard 1.95m/6-4.75. No athlete in the field currently holds the ‘A' standard.
Women's 1500m: Christin Wurth Thomas leads the field in the women's 1500m as the only American to run sub 4:05 so far this year. She ran a 4:03.62 to finish sixth at the Golden Gala in Rome. 2009 World Outdoor bronze medalist Shannon Rowbury will be in the field, but so far this year Rowbury has only managed to run a 4:11.67. Morgan Uceny, who finished third at the Pre Classic, and last year's outdoor champion Anna Pierce will also be in the field.
Women's 5000m/10,000m: Kara Goucher, Shalane Flanagan, Amy Begley and Desiree Davila. These four women have declared in both the 5000 and 10,000m for this year's national championships but all four have a better track record over the longer distance. Goucher, who took fourth in this year's Boston Marathon, has already earned a spot on the World team in the marathon but has said that if she earns a spot on the track she would forgo the marathon. Flanagan is the Olympic bronze medalist and currently holds the American record over 10,000m while Begley is a two-time 10,000m national champion. Davila burst onto the international scene with her runner-up finish at the 2011 Boston Marathon.
