EVIDENCE IN. USEFUL TRAINING OUT.
Your zones should come from what you can do—not your watch having a guess.
Add one recent effort. Zone Control turns it into a provisional six-zone profile, race evidence and one session with an actual job. Coach or lab validation upgrades the guesswork.

No heart-rate evidence supplied
One recent performance. Useful, not holy scripture.
Speed endurance with enough easy running to absorb it.
How this first version builds the profile
A race or 30-minute test is converted to an estimated 60-minute pace with the Riegel performance model (exponent 1.06). The six pace bands are Overdrive coaching guardrails around that anchor—not direct measurements of LT1 or LT2.
A known threshold HR remains authoritative. Otherwise a 30-minute field test uses the final 20-minute average directly; race HR is duration-conditioned and shown with a deliberately broad range. Wrist data widens that range, and efforts over two hours do not create automatic HR zones. A 30-minute time-trial study found useful group-level agreement but an individual HR error of about 8 bpm, so the range matters. View evidence.
Pace, pulse and purpose
Field-derived zones are provisional. Weather, terrain, fatigue and cardiac drift still exist. Annoying, but true.
Threshold builder
3 × 8 minutes controlled around LT1 with a 2-minute easy float. Fast enough to work. Calm enough to repeat.
Coach cue: The final rep should look like the first. If it turns into a death march, you missed the point.
A credible starting point—not a tattoo.
This profile is anchored to one effort. Use it for two to four weeks, watch pace at comparable heart rate, then move the ranges only when the evidence moves.
- 01
Easy days sit in Recovery or Aerobic. “Easy-ish but spicy” is how runners quietly ruin the week.
- 02
Use pace on flat, repeatable ground. Use heart rate and feel when heat, hills or fatigue change the cost.
- 03
A coach review or SPC lactate test can replace these provisional anchors with your actual thresholds.
