Today we had our first altitude training at an oxygen leval equal to 3.500 m above sea level in a row of 10 lessons.
Learned a lot about blod oxygen level and how this training works.
It went nicely. May be because we are used to skiing at such altitude at the Hintertux Glacier.
Will see how it goes next Saturday at 3.700 m.
