The meet begins on Wednesday and continues through Saturday afternoon. Most of the running event finals will take place over the final two days while field finals will occur each afternoon. The decathlon and heptathlon competitions will be held on Wednesday and Thursday.
Wallace, who enters the championship meet ranked fifth nationally, will race in the first of three semifinal heats of the 800 on Wednesday at 4:30 p.m. She has the second-fastest seed mark in her race, trailing only Natoya Goule of LSU who went 2:04.05 in the East Regional. Goule owns the nation's fastest time in 2:00.76. The top two from each heat plus the next two fastest times will advance to Friday's final at 5:20 p.m.
Marshall will take the track shortly after Wallace's race on Friday, opening the 100 semifinals at 5:30 and also looking to be either a top-two finisher in her heat or one of the next two fastest overall. She'll race in lane 2 of the third semifinal race. Marshall went 11.70 seconds at the regional meet but her school record (11.34) from the Big West Championships ranks her 16th nationally.
Marshall will have competitors from SMU, UCLA, Illinois, LSU, Florida, UCF and Florida A&M in her heat. The 100 final will take place at 5 p.m.
Fry, in her first season running the steeplechase, will compete in her semifinal on Thursday at 5:40 p.m. She'll race in the first of two prelims, each comprised of 12 runners. Fry's seed time of 9:58.97 is third-fastest in her race and just one of six faster than 10 minutes in the two races combined. The top five finishers in each heat plus the the next two best times will qualify for Saturday's final at 2:57 p.m.
"Reaching this final round of competition actually lifts some of the pressure, palpably present in Austin, to qualify to the championships," Wartenburg said. "At this stage, competing shoulder to shoulder among the 24 best athletes in one's event creates a unique and special opportunity.
"For the three women competing in Eugene this week, the meet is a chance to see how they measure up on a national scale, and on an individual level there will be important learning moments that they will be able to apply as their careers unfold," he added.
UC Davis did not qualify women for the national finals until discus thrower Ashley Hearn and 10,000-meter specialist Sarah Sumpter qualified for last year's meet in Des Moines, Iowa. Hearn finished third, earning All-America first-team honors, while Sumpter received second-team recognition after finishing 15th.
"Eugene stands as one of the best places in our country to compete in the sport of track & field due the competitive environment, unparalleled facilities and knowledgable fan base," said Wartenburg. "Hayward Field is a place where magical moments can happen, and I can't think of a better scenario for Lauren, Ashley and Katie to cap their 2013 collegiate seasons."
