I'd say that was the craziest day's racing I've seen in a long time! It was good – all three championships were decided and everybody could take risks in what were pretty difficult weather conditions. That made for extremely entertaining races and just showed you can't predict anything in MotoGP.
I didn't expect Dani to be so fast after starting the race on slick tyres, and his decision to come in just before the start of the race to change bikes and have to start from pit lane was the right one. He flew through the field and won by a margin we haven't seen for a very long time in MotoGP.
Jorge Lorenzo took the same decision to start on slicks and it looked like it was paying off before his huge crash, and it was just good to see him walk away from that one.
Having Katsuyuki Nakasuga, a test rider standing in for the injured Ben Spies, on the podium was amazing and absolutely nobody could have predicted anything even close to what we saw here at Valencia!
It was also great to see Casey Stoner on the podium in his last race. He wasn't feeling great on the bike all weekend but he leaves on a high and the real fairytale for him was winning at Phillip Island before his retirement. It's very sad he's leaving the sport but there are many things happening for next season, and 2013 starts this week with the test.
In full rain before we have seen that the Ducati goes really well and has had some great results, and if the weather had stayed as grim as it was most of the weekend I'm sure we would have seen both Valentino Rossi and Nicky Hayden fighting up there for the podium positions. However a case of tyre choice and the full rain holding off meant it didn't happen – Nicky crashed and Valentino lacked pace and it was a disappointing end to the season, which has been a tough one for the team.
I think everyone's looking forward to tackling the new season with a fresh approach, it looks like there will be some big changes at Ducati. I interviewed Nicky earlier this week ahead of the planned test, to maintain the forward momentum.
I have to mention Marc Márquez's win in Moto2 as well. Of all the riders I've met on track Casey Stoner was the fastest and we're losing him, but now someone comes in to replace him in MotoGP who can probably fill his shoes in a big way and that is Márquez.
What a last Moto2 race he had, starting from last on the grid and winning, and I am seriously excited about seeing him in the big class. I think when they find the right way to manage his impulsiveness on track, thanks to his pure speed I'm confident he could be another Casey Stoner. What we saw here was just incredible and it all makes for an exciting 2013!
