よくある質問
- What does it calculate?
- It relates pace, time, and distance: pace = time ÷ distance. Give it any two and it solves the third, and it can also project split times for race distances.
- What units does it support?
- Both kilometres and miles, with pace shown per km or per mile to match.
- Are the race-time projections exact?
- They assume an even pace throughout, so real finish times vary with terrain, fatigue, and conditions. Use them as planning targets rather than guarantees.
- Does my run data leave the browser?
- No. The pace and time arithmetic is done locally; the distances and times you enter are never uploaded or stored.
