I did it
This is just a brief update to let you know that I have done it! I summited Manaslu, the 8th highest mountain in the world, without the use of supplementary oxygen!
I will write more and post some pictures once I get back to Kathmandu or Switzerland, where I will be working for the next 4 months.
Thanks again for all your support and I can tell you – I am very happy to have summited an 8,000m peak without oxygen.
