Three key battles in Berlin
Many people ask if there is an Olympic hangover for an athlete the season after a Games. Not for me there wasn't.
A new season meant a new mission and this season that means the World Championships in Berlin.
There are those who left Beijing last year with gold and want to add another too show the world they are deserving of being the reigning Olympic champion.
And there are those who, in their minds, under-performed or had injuries in Olympic year, so want to make up for that.
One thing that stands out for me this year is potential head-to-head battles between athletes who got it right in Beijing and those who didn't.
Here are just three. Who do you think will win?
MEN'S 100M: USAIN BOLT v TYSON GAY
Since putting in performances hotter than the Olympic flame in Beijing, Bolt has become a superstar, not just because of his fast feet but for his exuberance.
But the triple Olympic champion and world record-holder currently lies second in the world rankings behind American Gay, who went into the Olympics carrying a hamstring injury and failed to qualify for the final.
They are different characters, with different techniques but they have the same mission: to be number one on the only stage that matters this season. Bolt wants the world to see that he can beat anyone and Gay wants to show the world that Bolt can be beaten.
Many believe that, if Gay he not been injured, he could have challenged Bolt in Beijing. I don't. Many think Gay could challenge Bolt in Berlin, I don't.
The reason why? I don't believe with the injury set-backs Gay has had, he has raced enough and is fit enough to go through the rounds and still challenge a man who can win whichever way he runs a race.
After his 200m victory at the London Grand Prix, Gay was very tired, walking the slowest lap of honour of the two-day meet.
I interviewed him there and felt that maybe time is not on his side leading into a major championships.
MEN'S TRIPLE JUMP: NELSON EVORA v PHILLIPS IDOWU
When I say Phillips Idowu didn't get it right, let me explain. Phillips himself says he didn't get it right.
"It hurts" and "I fell short" are just two of the phrases Phillips will say when you ask him about missing the "Big G" by just 5cm to Portugal's Nelson Evora.
Evora, the reigning world champion, leads this year's world rankings but is just 6cm ahead of the man who took silver in Beijing.
Knowing how long it took him to finally box his Beijing disappointment and bury it in the garden, I hope Phillips he hops, steps and jumps his way to the top of the podium.
WOMEN'S 400M: CHRISTINE OHURUOGU v SANYA RICHARDS
There are two big questions here. Is Christine Ohuruogo fit enough to defend her title and will America's Sanya Richards finally judge her race properly when it matters?
Christine has raced this year with the weight of the world title and the Olympic gold medal round her neck. It's a nice weight, but a weight nevertheless. Her plans have been knocked off track though because of a virus and hamstring injury.
Sanya may have the current world-leading time, as she did going into Beijing, but we all know Christine has a superb habit of getting it right when it matters, whatever circumstances she is coming into the Championships from.
