Logging time trials.

A time trial is any race or hard test effort you’d trust as your current fitness — a 5K, 10K, parkrun, the last mile of a long run if you genuinely buried it. Log it in Settings → Training inputs → Performance baselines → Time trials.

Each entry takes a distance, a time, and a date. We compute a VDOT score from the result and store it. Your current VDOT is whichever single trial yields the highest score — so a sharp mile effort can override an older 5K if the equivalent fitness is higher.

Once saved, the new VDOT picks up on the next weekly rebuild — every Easy / Marathon / Threshold / Interval / Repetition pace target shifts to match. Trials are kept in history so you can see your progression over time.
