Running The Amsterdam Marathon With My Sister

By October 23, 2025December 3rd, 2025No Comments

This past Sunday, I ran the Amsterdam Marathon with my sister.

Her first 26.2 miles / 42.2km ever.

Running the streets of Amsterdam together was incredible. But like most first-time marathoners, she was pretty nervous about those final miles – the last 10km that she’d never covered in training.

We hit the halfway point in 1:59:10. Then, at mile 20 (32km), everything changed.

Here’s what happened in those last 10k, plus our complete pacing and nutrition strategy:

This was a very special race and I’m incredibly proud of how she handled it!

Whether you’re training for your first marathon or looking to improve your race-day strategy, you’ll find practical insights in this video about pacing, staying patient through the tough miles, and knowing when to push.

Cheers,

Floris Gierman
