I have to admit I was doubtful when he originally announed his goal to break 1:05 early this year.
Then I saw this speed tuneup at altitude
* 3 x 1600m at 4:45, 4:42, 4:45
* 3 x 1000m at 2:59, 3:01, 3:02, 3:01
* 4 x 400m at 70-71
Combined with the fact that he's an aerobic monster, I think he can break 1:05.
Discus.
