hydration

Mark said:

I am looking for fluid replacement for use during and after long bike
rides. I do not know what is on the market and need some help in this
matter. Any suggestions would be greatly appreciated. Thanks in advance.

"Drink early, drink often" is the best, old-school advice.

Mix water and sports drinks. Commercial, deli-available drinks are
all about the same in terms of what you get out of them. The
expensive ones are just (literally) pissing your money down the drain.

There are speciality cycle drinks in powder and bottle form that are
supposed to replentish lost vital fluids and such with a higher
absorbsion rate then, lets say, Gatorade, but weighing cost vs.
effect needs to be determined by you.

1 liter per 20min. on a long ride is a decent base with adjustments
made for humidity, heat and overall exertion.

My personal favorite is Orange juice with Calcium. No sodium but
it is all natural and you get plenty of energy from the sugars.
Just my 2 cents.

That works on short rides. On longer rides, bring powdered sports drink and
mix it with tap water along the way. Most of the major brands of sports drink
will work fine. Use whatever tastes good to you.

I've heard 'an ounce per minute', and water is just fine.

1 liter per 20min.(clip)
^^^^^^^^^^^^^^

An ounce per minute is 20 oz per 20 min, which is pretty close to a liter
per 20 min. This is not an exact science, anyway.

That's a *lot* of water.

Water, there's no need for anything else. Tap water "works" as well as
"spring" water.

I agree. That's more than 3/4 gallon per hour. On a long ride, I might
drink 1/5 that amount (between 1 and 2 pints per hour, depending on weather).

A gallon of water is 8.33 pounds or 133.28 ounces.

60 ounces is 0.45 gallons

Correction. A gallon of water is listed as 128 ounces, so it
would seem that one ounce of water is heavier that one
ounce of dry material.

So that would mean that 60 ounces of water is 0.46875 gallons.

^^^^^^^^^^^
No wonder I always feel so waterlogged! I have never been able to choke
down more than about 0.46805 gallons or so.

You guys nit pick too much.
My personal experience to follow.
I ride in California where it is average about 95 on a summer day.
I tried an experiment a while back and weighed my self before and
after a one hour personal time trial against my self without
taking water. I came back about 3 pounds lighter and since I know
that I didn't lose 3 pounds of fat in that time it had to be water.
At that point I wasn't thirsty, just feeling the burn in my legs.
On a longer trip of about 9 hours and 80 miles bicycling, 5 miles
of hiking non rideable trails, and some rock climbing I did the
scale thing. I had started out with a gallon of orange juice in
my backpack, plus a number of bananas, pre-baked potatoes, and a few
apples. I consumed every bit of food and the gallon of orange juice
and still was about 4 pounds lighter when I got home. I was kind of
wasted (bonked?) on the last ten miles to home but not noticeably
thirsty. I had thought I was doing everything right but later it
dawned on me that I never had to water a buch during the whole 9
hours I was out. Even with the gallon of orange juice I must have
been slightly dehydrated.
I think the rule of drink early and drink often holds true.
I would rather make a few extra 'pit stops' than run out of water.

Not on a long ride or in high temp/humidity. You can get dehydrated
well before feeling thirsty so constantly sipping is a good thing.

Hydration systems are one of the best things long haul rider or hiker
can use.

From what I've read, 1 liter per hour is the high end suggestion
from the "experts". I've never heard of any recomendation of 1 liter
per 20 minutes. That sounds like a recipe for dilutional
hyponatremia, which is no fun at all.

I got hit with hyponatremia on last Saturday's Climb to Kaiser. At
about the half way point, dizziness, chills, nausea, and weakness
forced me off the bike. I had to lie down in the shade for almost an
hour until I was able to get back on the bike. Water and Endurolytes
revived me, but it still was hard to finish the next 78 miles to the
finish.

Maybe for you; it depends how much salt you lose in
your sweat. Many of us *need* to replace sodium
during long rides, most isotonic sports drinks do
the job.

The length of the ride doesn't really have anything to do with the rate of
fluid loss. Constant sipping doesn't do anything except prevent a belly full
of water, which isn't great jogging but is fine cycling. You will notice your
thirst before you become dehydrated if you're paying attention. 2 L/hr isn't
an impossible rate of fluid loss, but it's way on the high side, much too high
for a rule of thumb.

These things were designed for off-road biking, specifically to get the weight
off the bike to improve handling. They don't make any sense to use on the
road, especially on long rides.

If you do the math, you'll see that at nominal fluid loss/replenishment
levels, the average person will go through their salt reserves in somewhere
around 8 hr riding hard in warm weather (1L/hr). You'll also see that "sports
drinks" don't have enough salt to keep up. The bottom line: most people who
drink them don't need the salt they contain at all, but those who do need much
more than they provide.

Gatorade was designed specifically to rehydrate football players, who can't
drink while playing and require peak power outputs intermittently. The
addition of salt and sugar was primarily to increase the rate of absorption,
not to replenish salt or provide energy. Neither it nor its competitors have
any significant value for cycling.

If you ride long and hard enough to require salt replenishment, food is a
better source than "sports drinks", since most people can't tolerate drinking
that stuff for several hours (besides, it makes a sticky mess). The easiest
way to get your salt is to pop tablets. I fill gelatin capsules with 2/3 table
salt, 1/3 bicarb mix, supplement as needed with Doritos and V-8 (the distance
cyclist's drink of choice).

The Kaiser Pass is ~9150 ft., and the ride starts at ~350 ft. I had
spent the two prior days at altitude, riding the pass both days
without any discomfort, so I don't think altitude was the problem. I
reached Kaiser Pass at 6.5 hours and felt fine, but 30 minutes later
I was in trouble.

It was hot and exposed on the prior Big Creek climb (4.3 miles,
10%), and I was drenched with sweat. I think I simply sweated out
all my electrolytes. Plus, I wasn't drinking enough on the steeper
climbs. It's hard to climb steep grades and drink at the same time.
