Running Tracker

Log runs and analyze running performance using the data file at {baseDir}/runs.md.

Logging a New Run

Input parsing

Runs arrive in casual formats. Extract three fields:

• Distance: 1mi, 3k, 5k, 10k, 1.5mi, etc.
• Date: DD/MM/YY or natural language ("today", "yesterday"). If omitted, use today's date.
• Time: M:SS or MM:SS (duration to complete the distance).

Storage

Append a new row to the markdown table in {baseDir}/runs.md. Store dates as YYYY-MM-DD. Keep the table sorted by date ascending (newest at the bottom).

Response after logging

1. Run stats — compute and display:
• Pace (min/km)
• Speed (km/h)
• Estimated calories burned (use 62 cal/km, no elevation)

1. Progress note — 2-3 sentences comparing this run to recent history. Examples: pace trend, personal best alert, slowest/fastest in N days, streak observations. Be honest — if they slowed down, say so encouragingly.

Answering History Questions

Read {baseDir}/runs.md and compute whatever the user asks: averages, bests, trends, comparisons across distances, weekly/monthly summaries, training advice, etc.

Unit conversions

• 1 mile = 1.60934 km
• Pace = total minutes / distance in km
• Speed = distance in km / (time in hours)

When the user's question involves a distance they haven't run (e.g. 10k projections), extrapolate cautiously and note the assumption.
