>>gh will know or maybe J Squire, El Supremo
I'm amazed that someone thinks I know this. I wouldn't even know where to look it up. I doesn't surprise me, though. In general, runners who are great in U-18 competition rarely continue to improve. Ryun and Ovett are two exceptions to the rule. I remember reading that while Ryun ran something like 4:06 when he was 16, Keino ran about 5:40 at the same age (albeit under vastly different conditions). Don't hold me to specific numbers, though -- I'm going purely by memory!
