One year after claiming her first Olympic medal, former Colorado All-American Jenny Simpson once again has put herself in position to compete for a prestigious title.

On Saturday Simpson advanced through the semifinals of the 1,500-meter run at the IAAF World Championships in London, securing a place in the championship heat Monday afternoon.

Simpson, a bronze medalist in the same event at the Rio Olympic Games last summer, took more than three seconds off her preliminary heat time, finishing in 4 minutes, 5.4 seconds. The top five finishers in each heat, in addition to the top two at-large times, advanced to the finals. Simpson finished fourth in her heat.

While all three runners from the U.S. team advanced out of preliminaries, Simpson will be the only American in the final. Sara Vaughn, also a CU alum, saw her stirring summer come to an end with a 10th-place finish in the second heat. Vaughn finished in 4:06.83 after posting a personal-best 4:04.56 in the preliminaries. The final American runner, Kate Grace, finished 11th in the first heat (4:16.70).

Simpson will vie for the title Monday afternoon at 2:50 p.m. MDT.
