How to pace it.
slight negative split
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.
What blows it up.
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.
Adjust for the course
Same idea, different terrain.
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.
