Coaches: Could Sydney M.L. run 1:49.99/800 with specific training for 12-18 months?

Kelly Holmes was ripped, not bulky! Had the stature/physique suited to 800m/1500m.

I feel like a good comparison is Anna Hall - strongest at long sprints/hurdles, and runs the 200, 100H, and 800 in the pent. Sydney has faster PRs at 100H, 200, 400, and 400H and Anna just ran a 2:01 - surely Sydney could run that or faster right now with very little specific work, and could likely run 1:58 or faster if that was her main event.

She is a 400mH multi-time world record holder, Olympic and World Champion over 4x400m, 400mH, and 400m. She has a champion's mentality. She doesn't like to run the DL circuit. That is about it that is wrong there. She could train to win gold at 200m or 800m. It's just a question of priorities. 400m hurdlers who finish strong can run a good 800m. Her coach did get Mu to run sub-1:55. Sydney would break the world record in the 800m if she trained just for that, which she will never do. But look at Symmonds. He was a bulky runner and had barely any more sprint speed than Syd, yet ran 1:42.95, while Juantorena was, unlike Symmonds, a bulky 400m runner who won Olympic gold at 800m, and hence, is a good parallel.

Wariner was already cooked and nowhere near his peak abilities by the time he tried an 800m. He had the build and the fast 400m finish you'd look for in a possible 400/800 runner. But you have to have the desire as well.

There’s never been a sprinter/runner with 200-800m range. The fast-twitch muscles needed to run 21.5 for 200m are not built for endurance. Do believe Michael Johnson could have won a gold medal at 800m?
