Replying to the post "Would you run there?".

> By the way, I know this might look risky, but I think we often put ourselves in the skin of the person we’re watching, not in their mind.
>
> For me, a route like this is something I’ve prepared, and I know the terrain, the conditions and my own capacities on it. The consequence can be high, but that’s not the same as the risk, which depends a lot on preparation.
>
> Zero risk doesn’t exist, and I turn around in about half of my activities when things don’t add up.
>
> I wrote a longer piece on how I think about risk, if anyone is interested: [https://kilianjornet.substack.com/p/fear-risk-and-the-mountains](https://kilianjornet.substack.com/p/fear-risk-and-the-mountains)

Replying to a redditor:

> First it was high carb, then it was heat suits. What's the next training secret that's going to hit the masses?

> I don’t know about the masses but I believe that cognitive management will be the next frontier in performance.
>
> If we think about why we get tired, why we stop pushing...
>
> It’s (almost) never because of failure of one system. Our “body / central governor” prevents us to get to exhaustion and die from effort, and we see that athletes that perform the best are the ones that have a bigger pain tolerance.
>
> We see the effects of adrenaline, stress or the hormonal release during near dying experiences that indicates that we can push more than what our central governor is often telling us.
>
> So it’s more complicated than heat or fueling but IMO is the next big frontier.
>
> For the masses I believe probably Individualisation of everything (fueling, training load, oxygen systems, temperature system, renal system…) will have a huge impact because today most are following what works for others without analysing their individual circumstances and capacity.

Replying to a redditor:

> Is this really posted by the GOAT Killian Jornet?!? I think it's actually posted by Killian. This is an AMA that included evidence that it's him. Pretty cool, in my opinion.

> Yes, that's me!
