I'd probably just put prepared hot coffee in a flask. Brewing fresh in an aeropress with under-temp water will probably have similar mediocrity as 12 hour thermos coffee but with more dicking about, unless you're really keen on the process. It's not like you're having eggs benny on the terrace on a sunday morning - you'll just be after a reasonably tasty caffeine hit rather than pursuing the Nth degree of quality won't you?

the trouble with that is when i run out i have to brew more which eats into my rest stop time, with concentrate i can make up a ton and the only prep beyond that is to fill and boil a kettle during my dinner and breakfast stops. add in aeropress to that and I burn another 3-4 minutes time and time is probably going to be super tight to achieve my target distance.

than pursuing the Nth degree of quality won't you?yeah this is my thought exactly on pre-preparing it. saw some blog posts about making a concentrate and thought i'd see if anyone had any successes with it here.
Am off to a 24 hour ultra race in 3 weeks and will only have v. Limited time to prepare coffee during my breaks.
Is it madness to consider making up a big bottle of coffee concentrate the night before and then prepare each cup from 1/3 concentrate and 1/2 hot water from thermos which I can re fill once or twice during my meal breaks.
The other option is to use thermos hot water in an aero press. I tested the thermos and water was still steaming hot after 24hrs so should be piping hot for the 8 hours or so between refills. Ideally should be refuelling and changing kit on my breaks so this is a bit too much of a faff I think.
If concentrate is fine. What's the easiest way to knock up a large batch? Big Chemex brewer?
I should add I will have my own tent in camp where I take my breaks so all the kit will be staying there not carried
