Best pacing strategy
For most runners aiming for 3:30, a controlled first half is smarter than chasing time early. Aim to feel almost too comfortable through 10 km, steady through halfway, and focused from 30 km onward.
Common mistakes
- Starting faster than 4:50/km because the pace feels easy early.
- Banking time in the first half.
- Ignoring fuel until the legs already feel heavy.
- Not adjusting effort for hills, wind, or heat.
Race context
On a flat race like Chicago or Berlin, even pacing can work well.
On a rolling course, effort-based pacing is usually safer than forcing exact splits every kilometre.
