World champion sprinter Carmelita Jeter remains on the fence about whether she will run both the 100 and 200 at the U.S. Olympic trials later this month in Eugene, Ore.

Jeter said Wednesday she will compete in the 100 and then see how her legs feel. She will basically have five days to rest before the start of the 200.

The 32-year-old Jeter is coming off a sensational 2011 season in which she won the 100 at worlds in South Korea and finished second in the 200.

Jeter isn’t the only sprinter deciding whether or not to double at trials. Allyson Felix is up in the air about pairing another competition with her signature event, the 200. She may run either the 100 or 400 at trials as well.
