Tori Bowie just ran a 10.80 PB in Doha. Impressive.
Before you start wondering how fast she'll run by the end of the season realize the fastest 100m time for the men in the world last year was Justin Gatlin's 9.74 set in Doha as well.
Clearly the track if fast, but I'm making the assumption that the heat also helps with fast times.
It was 90 degrees when the meet started.
Most of the top meets are not run in that warm of weather. Anyone with more sprinting knowledge than me want to chime in on how much a difference warm weather makes?
