This year's Berlin (12.9% DNF) proved something... that even experienced runners do not know how to manage their effort for the conditions. You are 100% right that ultras are more technical but the real problem is that runners get so focused on a goal times that they fail to manage effort appropriately... the toughest part of altitude is that your body's max and resting heart rates shift (lower max, higher resting HR) thus your HR zones shift so even measuring effort by HR can go sideways. VO2MAX drops by around 15% at 10k ft (less if acclimatized but it still drops) and thus if you attempt to run at normal paces, you'll burn out due to over exertion.

50k is by definition an ultra. Tiktok commenters love to diminish people‘s accomplishments. You crushed it bro

When you exceed 42.2 km, it's an ultra marathon, end of discussion! Well done, buddy!

As if marathons aren't insanely impressive already. Adding any distance on top of that is just ridiculous. Even if its just a single km, let alone 8

Nobody ever talks about the elevation 😫. Did a 50km in Whistler w/ 10k ft of vert. Took me 8+ hours. 1000% an ultra lol.

Def an ultra. Problem is unlike the marathon which is always the same distance, this is not the case for ultra's, we just need names for the different ultra distances

People are morons. Most ultras are not flat land and are insane elevations

Great video. I’m super excited to run my first 50k at the Clearwater running festival in January. I humbly acknowledge that it’s just the tip of the “ultra” iceberg. But ultimately it’s the first step over 26.2 and it means something.
