Laros's 800-1500 conversion goes from 52.3/lap-55.9 (6.9%ish slowing from 8-15) ... Myers is 53.7-56.88 (5.9%ish slowing from 8-1500). Usually the endurance gets BETTER as they get older, and top speed is a more minuscule change. IF Laros gets down to 1:43flat (51.5) with that same percentage change in pace, it'd put him at 55.05/lap for 1500 (3:26.4ish). I believe he could do that. If Myers gets to 52.3 and kept the same percentage change from 800-1500, it's 55.4ish/lap (3:27.8ish). Granted, all of this assumes that their best performances were run in similar circumstances, primed for each, and gave 100%.
What's their mileage?...
My thought when I see stat lines, I'd put my money on Myers finding a home in the 5k/10k. 7:41 as an 18 year old off 3:33? these 3:58-4:00 18 year olds on this side of the pond are dropping 8:30-35 (59-64) (~8.5% change in pace) he's turning his (rounded) 57.0 to 61.5ish?! (about 7.9%) If you took that same rate and applied it to a "run of the mill" 4:20 miler, that 65 yields a 70 for 9:20. That's a common occurrence, but they are usually transitioned to the 5k in college, no?. That's the same as seeing a 4:40 girl run 10:00-10:05. Pre was 4:06/8:41 (61low-64.8ish
HOWEVER, I'm not belittling the ability to do that. He just eclipsed the lifetime bests of Ben Blankenship (3:34/7:44),Engles (3:33/7:44), we see 7.9% conversion (1500-3k) turns a 3:27mid (the aforementioned 55.4) to 7:28. That's almost exactly Nuguse's Olympic campaign. Let's say he came to the US this past year for school; I think you'd see him pull a Murphy/Langon/Martin XC/3k/5k at Boston. I bet he'd have been 10-15 in CC and pulled 7:35-40 or 13:10-15. Laros, on the other hand, would've likely challenged Blanks and the UNC guys at Boston and finished similarly to Myers in XC. Both are coming along, Laros is worlds ahead of him now; but I just feel their paths won't cross much after their mid-twenties.
