One race time. Every pace your athlete needs. Labeled by what it trains.

Every distance an athlete could race plays one of five architectural roles relative to whatever event you're actually training them for: Endurance Support, Direct Endurance, Specific Endurance, Direct Speed, and Speed Support. Change the target event above and watch the same seven race distances get relabeled. The role a pace plays isn't fixed to the distance; it's fixed to the relationship between that distance and the goal.

That's the whole idea behind “two events left, two events right”: physiology says why a pace matters, race pace says what to run, and the role tells you where it fits in the architecture.
