according to Sports Illustrated, , Delilah Muhammad had a pretty imperfect race when she set the world record at the USA Championships. They give some insight to her training as well. Muhammad regularly runs mile time trials the day after workouts. She runs "anywhere from 5:07 to 5:17." that's a lot faster than I would expect.
What I think is even more interesting, is her 800m times. Sports Illustrated said, "for 800-meter work, she could comfortably run 2:06 and she believed in a race, she’d dip under two minutes." what do you guys think about that? I don't think she could run under 2 minutes. I think that in a race, she could run 2:02-2:03. If she decided to train for the 800, then I could see sub 2 in 2-3 years.
