My lessons learned running a 100KM ultra marathon

Can you imagine running 100KM non stop through the mountains?

If you would have asked me two years ago I would have told you “no way, you are crazy”.

Now, two years later, I did just that.

I ran a 100KM ultra marathon in the mountains of Oregon with over 3.400 meters of elevation (12.000 feet). It took me 13 hours and 42 minutes to complete.

These are my learnings of going from ‘no way, you are crazy’ to training and running a 100KM ultra marathon.
