Saturday's going to be a long day of track and field at the 2016 Summer Olympics in Rio de Janeiro, with events running from the relatively early morning until nighttime.
The action starts at 8:30 a.m. ET, when a host of events will take place. The horn won't sound to start the last events until 7:50 p.m., and competition will be ongoing for much of the time in between.
Saturday's events include contests at various stages. The morning wave includes the final in men's discus throw, plus a handful of preliminary and qualifying rounds. The night will bring the final in the men's long jump and 10,000-meter run, plus the women's 100-meter run and 800-meter heptathlon.
So a bunch of medals are up for grabs, and the other events will get a lot of their heats done as they move toward medals over the next couple of days.
Here's complete viewing information for Saturday's track and field events. There's a lot going on, but you can stream all of it online. It'll be tense, and it'll be fun.
All times Eastern.
