HR zones vs pace zones — when to use which
2026-05-24 · zones, heart rate, pace, training, intensity
The two ways to control session intensity work on different logic. When HR wins (almost always), when pace wins (when terrain is flat and you know what you're doing), and why mixing them tends to backfire.
Active vs passive recovery — what the evidence actually says

The real difference between full rest and active recovery, when each one makes sense, what to do between hard sessions, and why a poorly-done rest day hurts your performance.
Altitude training — what it gives you, what it takes, when it's worth it

What altitude training actually does, how it affects performance during and after, how many weeks make sense, and the difference between live-high-train-low, live-high-train-high, and just showing up to race.
