I am quite an accomplished ultrathon runner (this thread will be in the training & ultrathon folders) so I decided to up the challenge.
I have entered the 'swiss alpine davos 79.4k' run in July, But i'm worried about the altitude disadvantage I have. The run starts at just over 1500m's & peaks at 2600m's. Thinking the U.K.'s highest mountain isn't even as high as the start is kind of daunting!
I was hoping someone who have ran/walked/climbed in high altitudes could give me some insight on what to expect, what differences there to your performance & if there is any way I can prepare before I get there.
Thank you all for your thoughts!
