One year on from the 2012 Olympic Games in London, the athletics' spotlight turns to Great Britain once more for Sainsbury's Anniversary Games.
The first day saw a number of big names compete inside Stratford's iconic Olympic Stadium. Despite a strong British contingent, Usain Bolt's return grabbed the biggest slew of headlines.
Just 12 months before, the Jamaican became the first man in history to defend his 100- and 200-meter crowns, ensuring his arrival would tempt many locales to the stadium once more.
With 14 track and field events taking place across Day 1, let's break down the key wins, events and memorable moments.
The King Returns
England's freak heatwave is on the cusp of ending with a number of storms lined up across the coming days, but London's only Bolt of lightning sped across the track on Friday. Bolt was in town once again, and as always, he didn't disappoint.
The iconic sprinter has done an awful lot of talking this week. Jamaican sport is currently struggling through doping allegations, forcing Bolt into confirming he is a clean champion, as reported by The Guardian. The six-time Olympic winner eased to 100-meter victory in front of the British crowd once again, producing a season best of 9.85 seconds.
Bolt finished ahead of USA's Michael Rodgers, who posted a time of 9.98. Jamaica's Nesta Carter took third place with 9.99, signalling just how easy Bolt's route to victory was.
The leggy runner didn't take part in the 200-meter race, but he saw fellow countrymen Warren Weir and Jason Young smash through the competition to finish first and second, respectively. USA's Wallace Spearmon followed the Jamaican duo in third.
Great Britain's Successful Homecoming
British sport is enjoying quite the summer of success. The British & Irish Lions overcame their Australian counterparts on Aussie territory, Andy Murray won his first Wimbledon title and the cricket team is currently up 2-0 in the Ashes.
Following on from the host's stunning performance at the 2012 Olympic Games, a number of British athletes performed well to secure victory in London.
While many of the starting lineups had a handful of top competitors missing, the British fans were nonetheless extremely pleased to witness their athletes performing well.
Emerging prospect Adam Gemili secured a well-deserved win with a time of 10.16 seconds in the boys' 100. While this race was made up entirely of British runners, the 19-year-old narrowly ousted Harry Aikines-Aryeetey, who also posted 10.16.
Gemili will be pleased to have won the meet, but as his career continues to progress at a rapid pace, he will be looking to improve on his season's best time.
Perri Shakes-Drayton followed Gemili's win with an excellent performance to finish second in the women's 400-meter hurdles. Her personal best of 53.67 seconds underlines a runner who continues to improve her power and strength against the best. Zuzan Hejnova claimed first place with a time of 53.07.
Great Britain's successful night was rounded off nicely with a win in the women's 4x100-meter relay. Although this featured All-Star and GBR Junior selections, the country's runners did a fine job of finishing in 42.69 seconds.
Certainly not the most competitive night, but an excellent opportunity for the home crowd to reminisce about last year's festival of sport.
Will British success continue into Day 2? The locals will continue to ooze confidence in their own backyard.
