Jay's a camel.

Not like Jobst. I fill up big bottles. I just don't take
more than two -- except on rare occasion. When selecting a
bike, I don't go into the store and ask for an '80s
Euro-sport bike with a rack so I can haul gallons of water on
a day ride.

Joerg has peculiar needs. I'm fine with a couple of bottle
bosses and 160mm brake rotors on a gravel bike. If I were
riding trails in the middle of nowhere, I might consider a
camel back or some other option, but I'm not. I'm never that
far from water on a day ride.

extra 16-24oz bottle of an energy drink for each hour on the
bike".

Most of my rides are 4-5h and I am a tall guy who is more at
the upper end of the water requirement scale. So there.

Yes, this also applies to Oregonians since they have a store in
Portland :-)

Your equation doesn't mention OAT which is critical to the
body's water usage. If one were riding in the Mojave desert on
the 4th of July your liquid requirement wouldn't be sufficient
and if in Nome on Christmas day it would be overkill.



It's not my equation, it is recommended by sports medicine guys and
they know a thing or two about dehydration. I assume they
calculated for heavy riding where you pump out close to as much as
your body will give at the current weather conditions. Note they
say "per hour", not "per xx miles".

For example, in summer I need almost 1/2h longer for one of my 4h
MTB loops because else I just start panting too much. In winter I
ride faster and that makes me pant and sweat just as much, and
consequently, drink just as much water. I'f I'd ride at the same
slower speed in winter I'd need much less water and sometimes I do
that. For example, when I just want to get out there to sit and
think about a difficult engineering task. Then I also take less in
fluids along.


I'm not really sure that they do. After all, dehydration that they're
talking about isn't from being out in the sun and wind but from
riding at or near maximum effort. I am showing no deleterious effects
from riding pretty long distances at moderate paces without much in
the way of hydration.


Sometimes the effects of dehydration aren't felt immediately but damage
can still be done, also longterm damage.

Arizonans take that topic really seriously:

Quote "If you're planning to ride over 25 miles, begin drinking fluids
the night before. If you need to get out of bed to urinate once or twice
during the night, your body should be sufficiently hydrated".

I don't quite go that far :-)

Their recommendation of 4 to 8 ounces every 15 minutes is a bit on the
low side. For example, while hiking rocky terrain in the Superstition
Mountains east of Phoenix we needed a whole lot more than that.

Dehydration is a very common cause of serious healtyh problems in
elderly people. When they are asked they respond "But I am not thirsty".
Thirst is not a good indicator because that can come a bit late in the
dehydration process.

My main hydration point on yesterday's ride was this:
