I predicted before the season Bol will run sub-51 for the 400 hurdles outdoors. She is going to have a jump similar to Dos Santos as she refines her technique. Her 400 abilities right now are obviously through the roof, and it’s just a matter of time before she destroys her hurdles PB. This is of course if she doesn’t focus more on the 400 which without Shaunae Miller-Uibo is pretty easy pickings (yes there’s Paulinho)
