As anyone knows who has worked a day job in their youth as a laborer,
either on a landscaping crew, or doing farm work where there's just
continuous activity, with a few planned breaks, you can lose a -lot-
of fluid.
On the landscaping crew, we were allowed to go shirtless, but had to
wear heavy long pants,( typically denim, and boots - somewhat of a
safety issue), and we were literally soaked the entire day. Most guys
brought a 2 gallon jug with a push-button spigot and emptied that and
more over a 9.5 hour day. You get thirsty right away and drink all
day.
But on a bike you presumably don't want to wait.
According to the babbling on OLN, team postal is drinking 16 bottles
of replacement fluid. The guy said they learned that you needed to
start out hydrated and then on the ride needed to replace up to 150%
of your starting fluid level. IOW, your body systems are using the
fluid constantly, so to avoid a post-post lowering, they go up to 150.
I don't yet get to the point of feeling thirsty at my level of riding
(1-2 hours), so right now, I go out hydrated, but don't drink on the
ride, and have a few glasses of water when I get back then a few large
coffees. That's probably unwise.
When did any of you get into your training (phase, level, physical
level) where it naturally started you carrying and drinking a lot of
water/fluids? I suspect in another 6 months I'll be up to the 2-3 hour
level of riding, and will start using my camelback.
