The NCAA indoor track championships get underway at 5:30 tonight, and there's plenty of action from the get go. To get you ready for Friday night's action, all of which is being streamed on ESPN3, we're previewing the three biggest races of the night. Let's get started.

Women's 1 mile

Ok, so this one is just the prelims, but it's right at the beginning of the meet and is guaranteed to be exciting. Oklahoma State Kaela Edwards looks to win her first NCAA championship after being the runner up in the indoor 800 last year, and she has a seed time of 4:32. Also in the mix is Andrea Keklak of Georgetown. The graduate transfer has been tearing up the track for the Hoyas, and she gets the chance to possibly go head to head with Edwards twice in this distance. There are two prelim races on Friday, and both should be fast and exciting.

Women's 3k

Seidel vs Ostrander for a national championship. Again. This is the matchup that everyone has been waiting for, and it's exciting to have that be on the first day. Seidel threw it down at the Meyo Invite on her home track, where she broke Molly Huddle's Notre Dame record in the 3k. Ostrander hasn't been slacking either this season, and this race is shaping up to be a classic.

Men's DMR

This event is just loaded and the action goes down at 9:45. Oklahoma State, Oregon, Stanford, Villanova, and Virginia. All of these teams have a legitimate shot at winning the event, and it's hard to pick any of them as a true favorite. To make it more interesting, most of these teams are in the running for the national championship, so a precious 10 points from the DMR would go a long way for these teams. Get ready for one of the wildest races.

While those three races are probably the most exciting on Friday night, there's still plenty of action in between them. The sprint events will be having their prelims and will not doubt bring some fire to the track. What races are you most looking forward to? Let us know in the comments below.
