Racing to 40:00
Even pacing is the most economical way to hit a time goal. Plan the first kilometre a few seconds slower than 4:00/km while the field spreads out, then settle. A small negative split — through halfway in 20:12, home in 19:48 — leaves room to finish strong.
GPS watches usually read slightly long on road courses, so trust the official markers and the elapsed times above rather than the watch’s average pace.
