Having been privileged to be sitting a few metres from the finishing line as Usain Bolt shattered his own 100 and 200m world records in Berlin - and having also witnessed his double in Beijing, I got to wondering where those performances ranked in my personal bag of live events.
So, here is my list of contenders, followed by my podium. I've included only events I have attended in a professional capacity as a sports reporter as memories of some others I've enjoyed as a "punter" might be clouded by beer.
In chronological order:
----
Jonathan Edwards soars in the triple jump, 1995 world championships, Gothenburg
OK, it was "only" the triple jump but the entire stadium was looking at Edwards when he set off down the runway for his opening jump. He seemed to defy gravity as he sailed 18.16 metres to become the first man to legally break the 18-metre mark. Twenty minutes later he went even further with 18.29 - a record that still stands.
----
England beat Netherlands 4-1 in Euro 96, Wembley
The moment when Terry Venables' side really looked as if they were going to deliver a big prize after "30 years of hurt." England's best display for decades tore the Dutch to shreds as the Alan Shearer/Teddy Sheringham strike force suggested that football really was coming home. It all went wrong in the semi-finals with a penalties defeat by Germany.
----
Michael Johnson completes 400 metres/200 metres double, 1996 Atlanta Olympics
The organisers re-arranged the programme so Johnson could have a crack at the unusual double and he did not disappoint, taking both titles with crushing displays. When he posed by the scoreboard showing a world record 19.32 seconds for the 200, clutching his golden spikes, it seemed his bizarre upright style might re-write the rules of running. Then came Bolt.

Zidane scores twice to lead France to victory in 1998 World Cup final
Zidane had bestrode France's bumpy journey to the final on home soil and though not renowned as a great header it was him who twice connected with corners to set up the emotional 3-0 win over Brazil. It earned his country the trophy for the first time and injected some much-needed fresh blood to a tournament so dominated by Brazil, Argentina, Germany and Italy.
----
Australia come back from the dead to win 1999 cricket World Cup semi-final on last ball
Australia were down and out midway through their semi-final against South Africa but through the bowling of Shane Warne and the sheer willpower of captain Steve Waugh, they got back into the game.
Even so, South Africa got to the last four balls needing one run to reach the final. That was when last pair Lance Klusener and Alan Donald had a collective panic attack and the Australians, calm, ordered and organised ran out Donald to secure a tie that sent them through on the basis of their Super Six record.
Wisden described it as the greatest-ever one-day international and Australia went on to beat Pakistan in the final.
----
Tiger Woods tames St Andrews in 2000 British Open
Woods went into the Open as a huge favourite but his display on the most famous course in golf stunned even his biggest fans.
During four days he guided his ball round the links course with such precision that had he walked it and placed the ball with his hand he would have been hard-pressed to improve his situation. He avoided every bunker on the course, on every round -- when the best of the rest were coming to grief on a regular basis -- and finished 19-under par to win by eight shots. Rarely since the days of Don Bradman could one sportsman be so far ahead of the rest of the pack.

Wilkinson wins rugby World Cup for England with extra-time drop goal, Sydney 2003
A superb England side should have had the game wrapped up in normal time and again in extra-time but Australia kept pegging them back with penalties.
In the last minute of extra-time they set up and perfectly executed a lineout followed by a break by Matt Dawson. Captain Martin Johnson, showing the clearest of thinking in the most pressurised moment of his career, took the ball closer to allow scrumhalf Matt Dawson to resume his position.
One pass to Wilkinson who, on his wrong foot, dropped the goal that won the trophy for England for the first time.
----
Czech Republic 3, Netherlands 2. Euro 2004 group game, Aveiro, Portugal
Probably not a match that most people would think of when asked for memorable clashes but this makes my list simply by being the best game of football I have ever seen.
The Czechs came from 2-0 down to win 3-2 with an 88th-minute winner from Vladimir Smicer and qualify for the quarter-finals.
The bare numbers, however, cannot begin to do justice to a match that both sides played with a total commitment to attack. They hammered the woodwork continually, forced both goalkeepers into endless saves, had no time for faking injuries or diving as they were all too busy trying to set up the next attack.
It is no exaggeration to say it could have been 8-8. A reminder why, when played like this, soccer is the sport that dominates the world.

Bolt dances across the line to win Olympic 100 metres in world record time, Beijing, 2008
It was supposed to be a three-way showdown between Bolt, Asafa Powell and Tyson Gay but it turned into an extraordinary one-man show.
Bolt flew down the track and, knowing the race was his 20 metres out, crossed the line thumping his chest in celebration. And yet he still broke the world record.
He followed up with victory in the 200, going all out for the line this time to break Michael Johnson's "untouchable" world mark in the process, then rounded it off with a third gold and third world record in the 4x100 relay. After years of destruction by dopers, athletics had the hero it so desperately needed.
----
South Africa secure series win over the Lions with last-minute 53-metre penalty, Pretoria 2009
It was not so much the iron nerve of 21-year-old Morne Steyn as he landed the penalty from within his own half to win the second test that made this special, but the entire match.
Trailing 1-0 in the series, the Lions delivered one of the most ferocious, aggressive displays seen in modern rugby to charge into what should have been an unassailable lead. World champions South Africa reeled, retreated, dug in and fought back.
For 80 minutes the two teams hammered at each other on and off the ball with staggering hits. Five Lions and three Springboks ended up in hospital.
The scores were level until local hero Steyn, on as a replacement, settled it.

Bolt does it again at world championships, Berlin 2009
Sprint world records are supposed to be nudged and nibbled but not once, but twice, Bolt took enormous 11 hundredths of a second chunks from his own marks with two astonishing runs on the iconic blue track of the Berlin Olympic Stadium.
It took me a long time to take in the "7" when Ben Johnson first posted 9.79 in the Seoul Olympics. Bolt's 9.69 from Beijing was still settling into memory banks a year on and suddenly the scoreboard was reading 9.58. It had to be impossible but I'd witnessed it with my own eyes, from about 10 yards to his right. I'm still not sure I believe it.
Four days later he did it again. 19.19 for the 200 metres. Running the bend, from a standing start, in 9.92 and the straight in 9.27.
For good measure he again topped it off with a relay gold, but had to settle for only the second-fastest time ever.
----
So, the podium. It's a tough one. For variety I'm not going to award Bolt two medals, he's got enough already.
Bronze: The 1999 cricket World Cup semi-final. It had everything -- a massive turnaround in fortunes, unbearable tension and victory for the team who kept their heads under crushing pressure -- thanks to the leadership of one of the all-time great captains from any sport - Steve Waugh.
Silver: Jonny's last-minute drop goal. Pure, unscriptable drama yet, as with the cricket, the extraordinary was built by doing the ordinary under pressure. Wilkinson takes the medal but, as he is always the first to acknowledge, the team's the thing.
Gold: It has to be Bolt. But though I never thought I'd live to see someone run the 100 metres in 9.6something, let alone 5something, it is his Beijing display that is my fondest memory.
It is the Olympics, the pinnacle of sport and the 100 metres is the pinnacle of the Olympics. You just don't win it laughing, dancing, celebrating, in a stunning world record.
But Bolt did, I know he did, I watched it and I'll never forget it until the day I die.
