@Anthony_Tate I struggled with this for so long. Like a really long time, and then felt like if it was going to happen anyway we may as well own it, and make it as tough as possible. I certainly have never watched any Netflix on an outdoor Everesting, and there are additional comforts (i.e. being able to change kit every 1,000m, having food on tap, being able to grab a shower) but then there are a couple of things that (in my mind) make some components of it harder. Being locked into the same position is a killer (although I negated that slightly by building a rocker plate for one indoor attempt).
I’ve DEFINITELY suffered more on some of my outdoor Everestings, but interestingly the vEverestings I’ve done would not have been the easiest.
I hear you on the Festive 500. I know for the first Rapha Rising challenge I did it was deep winter, and I rode through sleet to get the final vert. I would have been a bit miffed if indoor was an option back then.
Let me leave you with a final thought. At Hells 500 I like to use the mantra “Don’t worry about whether someone else has done it easier - think about how you can make your own effort harder”
