Day One: Some of Britain's top track and field athletes go up against many of the world's biggest names, including Deedee Trotter of the US in the women's 400m, ahead of the 2009 World Championships
Trotter and a competitive international field are beaten by Britain's Nicola Saunders, gunning for women's 400m gold in Berlin this August
The big draw tonight is Usain Bolt, the fastest man in the world, up against Asafa Powell, world number three, and both ease comfortably through their early heats in the men's 100m
The home crowd have more success to cheer as Britain's Jemma Simpson, Jenny Meadows and Marilyn Okoro take first, second and third place, respectively, in the women's 800m
The women's high jump competition is only ever about one woman: Blanka Vlasic of Croatia, current world number one and holder of the second-highest jump of all time, who clears the bar at 2.02m
Similarly, South London is treated to a sprint hurdles masterclass from Cuba's Dayron Robles, the world record holder and Olympic champion, though Barbados' Ryan Braithwaite pushes him right to the line in the final
Popular long-distance and cross-country runner Mo Farah of Newham and Essex Beagles - via Mogadishu and Hounslow - romps home in the men's 5000m
The last race of the night sees the flamboyant Bolt cruise to 100m victory in 9.91 seconds, way ahead of his compatriot Powell in sixth, and Britain's Simeon Williamson in fourth
Day Two: There's not a spare seat in Crystal Palace as the clouds gather but the weather stays warm with many home athletes competing for places in next month's World Championships
Tyson Gay, the closest sprint rival to Bolt and Powell, absolutely storms to victory in his men's 200m race in 20 seconds dead, well ahead of a field including Team GB's Marlon Devonish
Danny Crates, the British T46 (arm amputee) 800m world record holder and Paralympic champion, retires today; the 36-year-old finishing third but cheered home by the crowd and rival Marcin Awizen
Goldie Sayers needs little more than a competent performance with the javelin to make selection for Berlin but comes second with a 59.82m throw to Germany's 37-year-old Steffi Nerius (64.64m)
Olympic silver medallist Germaine Mason of Team GB clears 2.31m in the high jump, and nearly manages 2.33m, a good enough height to qualify for Berlin
The best British result of the afternoon is a lifetime best of 45.04 seconds for Michael Bingham (left) that beats both his compatriots and event-favourite Angelo Taylor in the men's 400m
Tirunesh Dibaba of Ethiopia is the easy winner of the women's 5,000m but the current women's outdoor world record holder and Olympic champion at the distance is still unsure whether she will appear in Berlin
Bolt makes his second appearance of the weekend anchoring the 4x100m relay for Racers Track Club in a time of 37.46 seconds, the fourth-fastest time in history
