Rene,
My issues are the first post. Could you imagine combining 1600 heats during track? How difficult would advancing become when there is twice as many bodies and twice as much talent? The Riverside course is wide at the very start and that's it... bad start and you are in the back. Sure there is tactics that can be used... but does anyone want to play games at prelims? Does anyone want to risk an injury on a crowded starting line and course? To tell you the truth, I'm just as worried for spectators running around the course as I am for the kids in the race...
