What happens between an athlete's final NCAA race and their professional debut? From finding an agent to signing a contract, our three-part series tells you everything you need to know.

Hasn't been done at a non-Olympic Trials since 1933.

Rudisha looked great, leading all qualifiers with his 1:45.09 as Murphy ran 1:46.18 behind him but only made the semis on time. Amos faded badly and was only seventh in his heat in 1:50.46 while American Charles Jock (6th in heat 4) was also among the casualties.

The Olympics are the one opportunity track and field has every four years to expand its fan base. With that in mind, each day, we're going to present to you an "LRC Friends and Family Guide" to the action - a quick overview of what to expect that day in track and field. Hopefully, you can share the link or print it out and hand it to your friends and family that are either casual track and field fans or not track and field fans at all. If they know the storylines behind what they are watching, they will enjoy it a whole lot more and you won't have to drive yourself nuts by starting at square one with them.

No man has repeated in the 800 at the Olympics since New Zealand's Peter Snell in 1960 & 1964. Defending world champ Rudisha enters as the world leader and favorite, but he'll be challenged by Kenyan Trials champ Alfred Kipketer, 2015 Worlds runner-up Adam Kszczot, France's Pierre-Ambroise Bosse and many more.

Ayanleh Souleiman won the 1500 in 3:31.68 with Ryan Hill 7th (3:35.38), Albert Rop dominated the 5K in 13:09.98, and Kenya's Timothy Kitum won the 800 (1:45.43) as Charles Jock was 10th (1:48.23). *MB: Ryan Hill runs 3:35 in Hesuden

What if a bunch of crazy stuff didn't happen at the Trials...

There were three first-time Olympians in the men's 800 as former Akron star Clayton Murphy got the win over world indoor champ Boris Berian.

Charles Jock ran 1:14.92 in the 600m to beat out Cas Loxsom (1:14.96), Eliud Rutto and Harun Abda. Sarah Vaughn won the 1500 in 4:11.39 from Cory McGee.

True ran 13:06 to seal the deal for worlds with Jenkins right behind him in a huge PR. Abbey D’Agostino PRd at 5000 as did Johnson to punch her ticket to worlds in the 1500. Other big names in action included Dejen Gebremeskel, Chris Derrick, Emily Sisson, Mary Cain, PVer Sandi Morris andLolo Jones. Check out how they did.

A lot of Americans competing including Bernard Lagat, Will Leer, Ben Blankenship, Garrett Heath, Lopez Lomong, Andy Bayer in the 3000, Charles Jock, Chanelle Price, Molly Ludlow, Gabriele Grunewald in the 800s. Also Melissa Bishop, Jenny Meadows and Lynsey Sharp. Asafa Powell and Yohan Blake are both in the 100, albeit in different heats. *Live Results

We feel very confident in predicting one thing about the 800s. Ajee Wilson and Boris Berian are going to Worlds. After that, it's going to be a lot of fun seeing what happens.

The Oregon Track Club's Charles Jock (800), Ben Blankenship (1500), Hassan Mead (5k/10k) and their coach Mark Rowland are focused on USAs and waiting to see what happens with the NOP doping investigation.

Georgetown alum Rachel Schneider got a solid PR to win the 1500 in 4:08.46 while Cory McGee was 3rd. Trinidad & Tobago's Michel Cedenio ran 44.97 to win comfortably over LaShawn Merritt (45.42); Jeremy Wariner was 9th (46.22).
*OTB: Ponce 800m - Charles Jock with the win, Symmonds showing signs of life *Nick Symmonds is BACK

There was a big fall, but no one was going to stop Duane Solomon from repeating as champion.

A great final with Duane Solomon, Erick Sowinski, Elijah Greer, RobbyAndrews, Cas Loxsom and others is all set, but we're still wondering about a questionable DQ of Nick Hartle.

Post-race reaction from Chanelle Price, Ajee Wilson, Brenda Martinez, Phoebe Wright, Lea Wallace, Laura Roesler, Charles Jock, Cas Loxsom, Robby Andrews, Sam Ellison, and Duane Solomon.
