Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| startDate | No | Start date in YYYY-MM-DD format. Omit for latest value only | |

Implementation Reference
- src/tools/performance.tools.ts:143-156 (registration)Tool 'get_lactate_threshold' is registered via server.registerTool with input schema from getLactateThresholdSchema. The handler calls client.getLactateThreshold() and returns JSON-formatted results.
server.registerTool( 'get_lactate_threshold', { description: 'Get lactate threshold data: HR and pace. Omit dates for latest. Provide dates for historical trend with aggregation (daily/weekly/monthly)', inputSchema: getLactateThresholdSchema.shape, }, async ({ startDate, endDate, aggregation }) => { const data = await client.getLactateThreshold(startDate, endDate, aggregation ?? 'daily'); return { content: [{ type: 'text' as const, text: JSON.stringify(data, null, 2) }], }; }, ); - src/tools/performance.tools.ts:150-155 (handler)Handler function for get_lactate_threshold: calls client.getLactateThreshold(startDate, endDate, aggregation ?? 'daily') and returns content as JSON string.
