Greatest Sporting Achievement of the Decade...

[Jeremy]

Probably Usain Bolt for smashing the 100m & 200m records, by huge margins. Twice.

Or maybe Manny Pacquiao for dominating boxing from Bantamweight all the way up to Welterweight.

[Atila Reincarnate]

The 49 game unbeaten run by the Arsenal which included going a season unbeaten. This was not about one or two games, but managing to keep up a run whilst still playing football the way it should be played.

[Keef]

Jeremy just picked the 2 I had in mind.

Bolt's 200m win broke a long standing record by another great, and unlike the 100m, you could see he was trying, and wanted it.

Also a shout out for Paula Radcliffe, who has had disappointments, but she won her debut marathon, then went on to break the world record, before breaking her own record, which still stands.

[Jah Lush]

I'd got for Ryan Giggs. Just count his medals. More than anyone else and still playing and winning things for Man Utd at 37.

[Narnia]

I'll second that. He never turned into the George Best I'd hoped he would but then that was almost impossible. However for longevity and his behaviour along with his ability he would be hard to beat.
