Michael and Kegan sit down with Nate Pack to discuss this year's annual Space Race, which occurs on New Years Eve. Previous editions include a 24-hour Assault Bike challenge in teams of three (580 miles was the final 'winning' score), 12-hour Dante's Triathlon (ski, row, bike 50-40-30-20-10 calories repeated in teams fo 3 or 4 depending on total weight of the team), and a 6-hour 40/400 AMRAP (40 calories plus 400m run) done solo. Continuing to cut total time by 50% would obviously lead to a 3-hour event and no one saw the point in that — the goal must be challenging and difficult enough to cause change or adaptation if that is what one seeks. And the power of having a date or deadline for performance, and people to do it with should not be underestimated.Once the structure of this year's event was determined they delve into the psychological (and physical) limitations of truly hard effort, the challenges of different time domains, and how most people never actually work hard but believe they do. Nate also discusses his impressions of the Capacity manual and the eight-week progression proposed therein ... and how ‘simple’ is much harder to abide than we imagine. Within this context they cover the various interval structures and training styles that helped develop them into the athletes they are today.Finally, Michael declares, "You have to rewrite what your brain thinks is hard in order to do something harder ..." and drops the mic.
