Generic plan — no paces in the file. Each run's "paceType" (test, recovery, easy, long, moderate, progression, threshold, interval, repetition, race) is turned into an actual pace by the app, calibrated from your logged benchmark "test" run. "progression" shows a start→finish range (run it as a build). "goal" + "weeks" are optional but power the pre-test estimates and progress. Only "date" is required per workout; skip a date or use "paceType": "rest" for a rest day. A re-test mid-plan recalibrates the rest. (Legacy plans with an explicit "pace" per run still work.)
