BOSTON -- Allen Johnson is trying to overcome a series of injuries to make one more Olympic team at age 37.
Twenty-five-year-old Lolo Jones is aiming for Beijing after rebounding from a disappointing 2004 Olympic trials.
Both will run the 60-meter hurdles over the weekend, races expected to be among the most hotly contested events in this weekend's U.S. Indoor Track and Field Championships.
It's the final stop in the 2008 Indoor Visa Championship Series, with national indoor titles and roster spots for the 2008 IAAF World Indoor Track and Field Championships at stake.
Many of the U.S. elite track and field athletes have chosen to forego the indoor championships in this Olympic year. But some hope to use the indoor championships as a springboard for the outdoor season and the Olympic trials this summer.
