I love the 300m! 33.05 is smokin'!
Looks like he ran the 300 last indoor season (2012) in 34.08 before his 46.37 outdoors.
He's also run 500m indoors this year in 63.39 vs. 64.20 last year.
He's also run 400m indoors this year in 48.08 vs. 49.20 last year.
So, 1.03" improvemnt in 300m, 1.12" improvement in 400i, 0.81" improvment in 500m.
I'm thinking 45-low this year outdoors. Probably not 44.xx, but could be close!
