Remittance Man defeating Katabatic & Waterloo Boy in the 1992 Champion Chase has always been my favourite national hunt race. It was billed as ''Man vs boy'' and in the end Katabatic split the two of them in a great finish.
Gloria Victis slamming the 2000 Racing Post Chase field was incredibly exciting. The way the horse attacked his fences and relentlessly galloped his rivals into the ground was a joy to watch.
Moscow Flyer vs Azertyuiop vs Well Chief in the Tingle Creek Chase. To have three such outstanding horses around at the same time was speical. Hearing the crowd roar when MF hit the front over the railway fences really got the pulse racing.
Desert Orchid drawing clear in the home straight to win his fourth King George was fantastic.
On the flat I'd pick out Arazi's astonashing BC Juvenile victory.

Also, Zafonic's amazing performance to win the 1993 2,000 Guineas, especially the moment in the race when Graham Goode says in commentary '' Zafonic on the left is absalutely pulling double!''. He like everyone else couldn't really believe what they were seeing at the time!
The 1989 Queen Elizabeth II Stakes is a forgotten gem. It was the undefeated Zilzal vs the undefeated Polish Precedent for the title of champion miler. When they turned into the home straight first and second it was set for great finish. In the end Zilzal put in a performance of extremely high class miler to draw away from his French rival.
More recently I'd have to go to the Breeders Cup again and pick out the 2000 & 2001 Breeders Cup Classics.

The outstanding Tom Durkin was sensational on commentary as usual in both races. He has been a big loss to the BC coverage over the past few years.
