Common mistakes

  • Running the first half in 1:42 — the second half becomes a death march
  • Relying on race-day gels only — practice your gel timing in training
  • Going out with the 3:15 crowd at the start — their pace will feel easy and ruin you

Key race day tips

  • Target 1:46 for the first half — bank nothing, spend nothing
  • Gel every 35–40 minutes from 45 minutes in
  • km 28–35 is the danger zone — shorten your stride, don't slow your cadence
