2:14:00 at Twin Cities (2014)
2:12:56 at USA Marathon Championships in LA on a warm day
2:13:00 at the Trials - basically right at his PR on another warm day
2:11:30 at the Olympic Marathon for 6th - 1:26 PR in sub-optimal conditions
Looks like him and Eyestone really know what they're doing. Of course, it probably helps that he wrote his Master's thesis on marathon pace strategy.
Not trying to detract from what Rupp just did at all - (awesome bronze medal run and 1:08 PR for him), but this guy has had an awesome and very consistent progression when he has the tendency to get overlooked. Ward is the man!
