I'm just curious if fascinated with endurance, like it's effects on the body. I'll switch switches for physical, so like mental after like certain miles that you don't want to be legs anymore, you're on your own with your mind. Overcoming that mountain desire to stop endurance, so like any other sport. endurance implies something more sustained if you were like almost like holding your finger in the fire long enough to feel the heat. So I like to use as an analogy and keep in your finger there. I'm Domainzley, mountain athlete, in 2020 I'm going to break the Wainwright's World Record in summer and winter. 214 peaks in the latest trip, basic debris, recognised peak. It's 320 miles, over 36,000 metres of elevation. Third day, it'll be running about 2 and a half miles per day. I've got over 6,000 metres of elevation running for around 20 hours per day, resting for about 34. I like to push them into the ocean and do, I'm really competitive on the whole of myself. I'm not care about competing over people, it's not what I can do, how far I can push it. Yeah, I'm going to go to the edge. Thank you.
