I'd have thought that the biggest issue in that situation is the initial sorting/culling of the files - you're not going to need, use (sell?) all 3,000.
How many images in that scenario will you eventually end up using? Less than 100? Less than 50?
"Using"= making available to the athletes for personal purchase, so all 3000--which is the culled list out of likely 5000+ shots.
Brain, yup, single sport event with a couple hundred athletes have a whole lot more "breathing" time, but 2 hours to get CD to organize--YIKES!? I try to get a top hundred shots posted by end of the day, but takes the rest of the week to get thru them all. What race are you shooting?
