Effort for km 1Hold back
Part 1 of 5: Settle in
Hold back. Relax your shoulders, find some space and check your pace once, not every 10 seconds.
Start easy
The first 2 km are planned a little slower than 5:38/km. Crowds and adrenaline make it feel too easy, so hold back.
What you will feel: Crowded, loud and exciting. The first kilometre will feel far too easy.
“Patience now, pace later.”
