Thank you all for your responses. I knew I had messed up but I was not close to any water source, home, store, etc, and at the time I just needed to lower my head and clear my head. The additional mistake was when I was back on my feet and walking back toward home a neighbor with a pickup stopped to see if I was OK, offered a ride and my ego said no thanks, I am fine.
I am looking at the air pump taking up a spot where a second water bottle could be mounted. Luckly our Fall is comming soon and this humidity should come down.
Thanks gain all, Frank.

Yes, have at least two bottles with you on your ride. And if possible, know where, along your route, you can get more.

not sure if this has been suggested but when taking your BP after exercise you are supposed to wait about 45 minutes to an hour.

SylvainG

Unless you want to know your exercise BP.(which systolic could go as high as 200) or how fast your blood pressure return to normal after exercising.

I took my BP about 3 hours later. I wanted to get my core temp back to normal so I sat in our dinette and allowed the AC and fluids to help me normalize. Took a shower and then took the BP.

ok, yes but I was just pointing out if you DO take your BP right after it's not your normal bp reading, that's all

is good for you, but don't get dehydrated like that. The more you do it, the stronger and fitter you'll get. One bottle to one liter/hour is decent fluid consumption in hot weather. Make sure you have that capability. Watch your forearms. Don't let them get dry. A heart rate monitor is a good tool. If your HR gets unusually high for the effort, you're dehydrated. If you do get dehydrated, find a water source with shade. Sit and drink until you pee.

Thanks again to all for your responses.

I've added a stainless steel double wall insulated thermos that fits my bottle cages. It'll keep water/electrolytes cold for hours even in summer daytime heat. Very handy on long rural rides where it may be 5-10 miles between opportunities to refill or buy a drink. It's heavy but worth the extra weight in the heat.

If I fill the stainless bottle halfway with concentrated electrolyte/water mix and freeze it, the frozen bit will stay cold for 8-12 hours depending on outside temperature. I just top up with plain water at every opportunity. If I freeze just plain water it'll stay cold about 4-6 hours. Apparently the electrolytes keep the water frozen longer.

I also have a collapsible Mylar water bag that I freeze and keep in my jersey pocket. Keeps me cool for awhile just sitting against my back. Then when it melts I use it to wet my head and skin.

There are mini-pump frame holders that mount under a water bottle cage, so no need to give up one or the other. My mini-pumps (Topeak RaceRocket HP, Blackburn Core Slim) need 200-300 strokes to fill my hybrid or skinny road bike tires, but it's not hard effort, just takes patience compared with my older Zefal full length frame pump. And I'm planning to get CO2 for days when I don't feel like messing with pumps -- especially since I'm still recovering from a shoulder injury that limits my right arm strength and flexibility. CO2 would be much less physically stressful on hot days too.

Well salt do lower the freezing point of water to -17C so yeah, it will stay frozen longer.

Btw, that's how you make ice cream. You put cream (and other stuff) in the creamer where its wall are kept frozen with a mix of salt, water and ice cube. By scraping the inside on the creamer, you end up with ice cream

Yup, I seem to recall Doc Isotope mentioning that trick a year or so ago, comparing it to making ice cream. Made sense. I remember spending a lot of summers hand-cranking ice cream makers at my grandparents' home years ago.

Tried it on my plastic bottles and it seemed to keep them cold longer last summer. But with the insulated stainless bottle there's a significant difference. The concentrated electrolytes will stay frozen almost too long. Sometimes I'd prefer the electrolyte ice would melt sooner and diffuse into the water.

I took that stainless bottle, half filled with frozen electrolytes, out of the freezer at 5 am today for a bus ride to the doctor's office for an ultrasound. Then I stopped at a friend's home to pick up a bike he was holding for me so I could ride the 12 miles home -- the temp was nearly 100. I refilled it with warm water from the MUP trailside rest stop about halfway home. Then I took a nap. The frozen stuff finally thawed by 5 pm, but was still ice cold.

Might be a stupid question but how to you drink out of a steel bottle while riding? Obviously you can't squeeze it (can you?).

noglider 

Some of them have tops with a valve, so you can suck on it.

zonatandem

Geez Louise . . . . take top off bottle and drink!

Only if you're The Six Million Dollar Man.

I bought a Stainless Camelbak 53892 Eddy Vacuum bottle. In 30C temperature this weekend, even after 4 hours (3 of them riding), still had lots of ice in the bottle. Only issue is my bottle cage is aluminum so its metal against metal which scratches the bottle and rattles a bit.

Sal Bandini

My wife has small bike frame so only one cage will fit. She drinks a lot more water than I so I put this on her handlebar. I would suggest this or something similar:

This is a great idea. Thanks.
