The Week That Was is in fine form this week as we talk about Galen Rupp's half in Philly, Jordan Hasay's slowdown in Philly, sub-4 mania in Alaska, races with interesting prize money structures and of course the two super-fast half marathons in Europe.

Kamworor cemented his status as the biggest young talent in the sport with by coming from 12 seconds down on the final lap to overcome a heroic effort by Uganda's Joshua Cheptegei.

Geoffrey Kamworor is looking to become the 1st man since 2006 to successfully defend his world cross country crown. Can he do it? If he falters, who is likely to win? Can the Americans possibly pick up their first individual medal since Alberto Salazar's silver in 1982? They've certainly got a good chance, particularly if Olympic 5000 silver medallist Paul Chelimo, who is in Uganda ready to race the 10k (but currently only on the 4 x 2k relay), ends up running.

Thomas Curtin, Trevor Dunbar and Ford Palmer are also in the field. Women's race has Serena Burla and Natosha Rogers.

True will face Olympic silver medalist Dejen Gebremeskel, Stephen Sambu and Diego Estrada while Huddle is up against Kim Smith and Buze Diriba (14:50 PB). Also Saturday, Chris O'Hare, Trevor Dunbar, Dawit Seyaum (2nd at World Indoors) and Heather Kampf lead the way in the BAA Mile.

Heath is up against Craig Miller, Trevor Dunbar, Jeff See and Aaron Brun. Kampf faces Payton Jordan 1500 winner Rebecca Addison.

Track fans, this one is loaded with former NCAA stars. That's the good news. The bad news is you gotta choose, this or Mayweather - Pacquiao. More bad news, HSer Grant Fisher might go sub-4 but it won't count - unless Stanford changes from a 1,500 to a mile in the next 24 hours.

Stacked fields for every distance event. Also in the 10K field are Juan Luis Barrios, Futsum Zienasellassie, Fernando Cabada, Kemoy Campbell, Trevor Dunbar. More meet highlights include: Women's 10K: Shalane Flanagan, Dominque Scott, Kate Avery. Men's 1500: Lopez Lomong, German Fernandez, Stanley Kebenei, Andy Bayer (also listed in steeple). Women's 5000: Emma Bates, Juliet Bottorff, Tara Erdmann, Gabe Grunewald, Marielle Hall, Nelly Spence Gracey.

Sunday was the best and worst of times for many top runners. Reaction from the likes of Usain Bolt, Shalane Flanagan, Andrew Wheating, Kyle Merber, Trevor Dunbar, Riley Masters, LaShawn Merritt, Heather Kampf, Nick Symmonds, Tom Farrell, Brianna Rollins and more.

Lagat got the job done yet again as expected since Galen Rupp wasn't in the field. Or was he?

King Cheserek waited until the final 250, but boy was it special as he remained undefeated for his life at NCAA champs.
