Sport analytics page tour: bike, run, swim, Yousuli Help

What this page is

/athlete/<public_id>/analytics/<sport>/ is the sport-specific deep-dive view. There is one for each of bike, run, and swim. Each one pulls together the metrics, curves, and zone breakdowns that make up the athlete's profile in that sport.

What appears on each variant

Common to all sports

Threshold anchor: CP for bike, run threshold pace / run CP for run, CSS for swim.
Volume summary across recent windows.
Trend chart of the threshold over time, built from MetricHistory entries with source tags.

Bike-specific

Power spectrum: VT1 (aerobic threshold), VT2 (anaerobic threshold = CP), pVO2max (Power at VO2max). VT1 comes from a lab test if you have one, otherwise estimated at 77% of CP. VT2 is your CP. pVO2max is either a coach override or your career-best 5-minute power (sanity-checked: if CP >= pVO2max, the system substitutes CP * 1.18 to keep the zones consistent).
Power curve (MMP) from career best at each duration.
Sensor summary: pedal balance, torque effectiveness, pedal smoothness if your power meter records them.

Run-specific

Power spectrum for run power: same VT1/VT2/pVO2max structure, anchored to run CP if available.
Pace curve built from best_pace_curve on activities.
Run dynamics: cadence, ground contact time, vertical oscillation, leg spring stiffness when Stryd or compatible device is present.

Swim-specific

CSS pace and trend.
Pace-duration curve (PDC): distance-pace combinations from recent training and tests.
Best paces at standard pool distances (100, 200, 400, 800, 1500 m).
Swim metrics: stroke rate, distance per stroke, SWOLF, per-lap distributions.
EO SwimBETTER session list if the athlete has uploaded any EO reports.

Filters

Date window (default 90 days; presets at 30, 90, 180, 365 days).
For bike: outdoor vs indoor sub-sport filter.

How freshness shows up

Each threshold is tagged with its source ("verified", "calculator", "modeled", "manual") and its age. If a value is stale or expired, the page shows an "aging" or "retest recommended" pill next to it so the coach knows the projections downstream are working from old data.
