Reading your weekly volume chart

What the chart shows

The weekly volume chart on your dashboard plots what you actually did, not what the plan asked for. For each week in the chosen window (default: last 12, can go up to 260) it reports:

• Hours of training in each sport (swim, bike, run, strength, other).
• Load in each sport (using tss_override if a coach has set one for an activity, otherwise the auto-computed Load).
• Activity count per sport.

API source: GET /api/athlete/<id>/weekly-volume/?weeks=<N>.

How weeks are defined

Weeks are Monday to Sunday. The current week is always the rightmost bar in the chart. A week that has not finished yet shows the totals so far (so Monday morning of any week will show a near-empty current week).

What "effective Load" means

The Load reported on the chart is tss_override if your coach has overridden it for an activity, otherwise the auto-computed Load. The override path is described in Load computation and the coach override.

Reading the trend

Three signals to watch over a 4 to 8 week window:

• Ramp rate: how fast total Load is climbing week over week. A jump of more than 10 to 15 percent for several weeks is a common over-reaching pattern.
• Sport balance: the proportion of Load by sport. A triathlete heavily skewing to one sport for a stretch is usually doing it on purpose; if you are surprised, ask your coach.
• Recovery weeks: scheduled volume drops every 3 to 4 weeks. If yours are not appearing, the plan might be missing them.

Reading hours vs Load together

• High hours + low Load = lots of easy aerobic work (typical base block).
• Moderate hours + high Load = intensity-heavy weeks (build or peak).
• Low hours + high Load = short and hard (rare; usually means the easy work got squeezed out by life).
• Low hours + low Load = recovery week or unintentional gap.

What the chart does NOT show

• Planned volume targets: those live in your macrocycle plan (the config_json) and are not yet surfaced on this chart. Compare against the plan yourself, or ask your coach.
• Future weeks: only past and current.
• Per-day breakdown: the chart is week-level; for per-day detail go to the activity feed or the sport analytics page.
