You will have to eat and drink a lot
during your effort, so think not only where to get the supplies, but also where to store everything you need and the disposal. Nutrition is a personalised subject, so I will only note that you probably shouldn’t try anything new on the important day.
You will need front and back lights that must have enough battery for the entire night
. If your route is covered with streetlamps, it’s easy to just use a low mode in front. However, if at least any portion of the route is dark, you want high beam — that depletes the battery quick. I like headlights with a removable 18650, or better yet 21700, battery — it is more efficient to carry a couple of spare ones than to charge from power banks (that likely have same 21700 elements inside, but additional bulk & weight of the shell and some efficiency loss when charging). Let alone the convenience of just swapping the internal batteries instead of plugging and dangling the external.
With an exception of maybe a couple of models, no cycling computer can last an everesting attempt on a single charge. For that you need either a power bank or an accessible socket
— most likely, plugging in when taking even the shortest of standing rests is sufficient to keep the thing going. A minimalist charger is okay to carry up and down on yourself, but with the weight of a power bank I would think of where to stash it (which kinda defeats the purpose).
You may want to prepare a good range of clothing. I usually like to be minimal with apparel — and am quite tolerant to being under- or overdressed for the weather — but that’s where I made the biggest mistake in my everesting
(so that you won’t).
In my geography and season the temperature on the day dropped from the high of 28°C in daytime to 6°C in the night. Just a week before the everesting I was in a cycling camp where I was starting everyday rides with a long descend at the low temperature
of 7°C — wearing just summer jersey and bibs — which was unpleasant, but tolerable.
