I read this thread and these debates aren't really anything new -- I'm a former runner and former racewalker who had success at both disciplines.
I understand that it looks awkward/ridiculous and doesn't enjoy a great tradition or history in the US. BUT on a global scale it is a pretty popular event -->
It has been in every Olympic Games in one form another -- except 1896
Spain's first Olympic Gold in Track and Field was in the Men's 20K in 1992 and the event remains quite popular there.
Ecuador's ONLY Olympic medal of any color (and first South American man to win a gold) was in the 20K also.
Mexican 'Walk Week' races have had 50,000+ spectators.
Robert Korzeniowski (sp?) of Poland won the 20K and 50K at the same olympics and the 50K in three games in a row. No one dares say he is anything less than a great ambassador for the sport of Athletics.
So.. the event is really not going anywhere just because it isn't 'liked' by American trackers. With that said ... I think Curt Clausen's Bronze in the 50K at the 1999 Worlds was the first medal by an American man in a distance event at World/Olympic competition in a long time ... certainly a notable thing.
On a personal note -- I struggled as a runner (mostly because I was a headcase)... I became a well regarded race walker (I grew up overseas and learned the event at a young age) and actually ended up running some great times off my racewalk training. I know this may sound SHOCKING to people on this list, but there are cases of runners using racewalking to suplement their training -- it can help develop some neglected muscle groups and is fantastic for injury recovery (less shock on impact).
I invite everybody to embrace the event -- remember the sport is Track & Field and racewalking is just another event ... the javelin is not a terribly natural thing and the US doesn't enjoy great success in it -- but that doesn't mean it is not worthy of respect...
Thanks for your time...
