Jeff & Tiffany Porter: Top 10 Instagram Photos

Jeff and Tiffany Porter are both running hurdles at the Rio Olympics, but are representing two different countries despite both being born in the U.S. Jeff is running for the U.S., while Tiffany runs for Team Great Britain. Tiffany's younger sister, Cindy Olifi, is also running for Team Great Britain.

On Tuesday, Jeff will run in the semifinals and possibly the final of the men's 110-meter hurdles. He had the eighth-best time after the heats with a 13.50. Tiffany made the semifinals in the women's 100m hurdles, which are on Wednesday. She had the 14th-best time in the heats with 12.87. Her sister did much better, running 12.75.

The 30-year-old Jeff and 28-year-old Tiffany also ran in the London Olympics, but both failed to reach the finals in their events. This will probably be their last shot at Olympic medals.
