Riding in the HEAT

Start by scrolling up.  There is lots of good advice.

Gatorade and typical sports drinks are pretty much only good when you're fully hydrated.  When you're dehydrated, they're too thick for easy digestion.  That's why Osmo and Skratch were created.  All the salt and electrolytes, about half the sugar.

Likewise, the tablets from Noon, Zym, Hammer, Gu, are good for hot days.  You can easily carry them in your pocket and drop them in plain water and you're good to go.  I don't think they have enough in the way of electrolytes, but they're pretty good, and drinking plain water can get boring.

Pre-cool when you can.  Drink cold water before going out.   Then, after drying the sunscreen on your arms and legs, wet your head (if you've got hair on it) and your jersey before putting it on.  Squeeze out the excess water so it doesn't drip into your chamois or shoes.  

Use insulated bottles.  Start with them filled with ice cubes and cold fluid.  They'll eventually get to outdoor temperature, but for the first hour or so, it's a benefit.

I'm not a fan of the cooling sleeves.  i think they're for dryer climates than ours.  With the high humidity, your arms are covered in sweat anyways.  I think the cooling sleeves work better in dry conditions where your sweat is evaporating so quickly that holding the sweat on their is cooling.  

Summer jerseys do make a difference.  I believe I can feel the difference between our normal jersey and the summer one.  The summer skin suit is even thinner.  

For the past decade, I've been going to Las Vegas in September.  I test ride bikes every time.  It's usually over 100 degrees and I'm out in the desert from 11-5 the first day and 8-5 the second.  One year it was around 115.  Basically, I'd pour a bottle of water over my head and jersey and drink a bottle of water.  Have a bottle of something with me.  Ride for 30 minutes and drink the bottle.  Then another bottle of water over the head and jersey and drink another bottle of something.  Repeat every test ride.  No heat stroke there, yet. 
Osmo is "restructuring"?   What should/can I buy currently to help with the heat?  Can I buy from Red Beard?
thanks y'all

Osmo is probably gone.  

Redbeard has Skratch, among other offerings.
Ooh Skratch...quite the conundrum...Now I want to give my team sponsor my patronage but I DO NOT want to give Dr. Allen Lim my "scratch"...
Dr. Feelgood carried Floyd's drugs in 2005...and cashed several of FLoyd's checks
"“Lim carried my doping supplies and delivered them to me through the 2005 Tour,” Landis toldCyclingnews.

“If he'd been against it as he claims and wanted to stop me all he'd have to have done is simply discard them. Not once did he fail to deliver what I needed.”


Which brand of gasoline do you put in your car Yacks?  
CAM2 100 octane racing fuel.....duh


Sunoco – rated the 3rd worst polluter in US, 2010 Toxic 100 index. Word.
So they are on the podium...maybe next year they will take the crown
How do I setup a Polluter Fantasy team?
two articles on dealing with the heat

One from Skratch: http://blog.skratchlabs.com/blog/make-thirst-work-for-you

One from CTS: trainright.com/how-to-prepare-for-exercising-in-the-heat

Both are from morally compromised sources.  But it doesn't mean the advice is bad.


Morally compromised, is that a euphemism for Doping Enabler?

How'd you figure it out? ;)

The sad thing is that Lim had the chops to earn his place without helping Floyd, Levi, probably Mike Barry, possibly Lance, some others with the dark side.  I think he's staying away from pro cycling (other than hiring clean retired riders to work for/with him) because he doesn't want the doping enabling to come up.

Carmichael, on the other hand...
So, I rode for seven hours today.  Left when it was 86f out.

I started with my insulated bottles filled with ice cubes and cold water filled with Osmo.  I had four Osmo packets in my pocket, as well as two Clif bars, and several Clif ropes.

The first two bottles lasted two hours.  I refilled in Ringwood, NJ, with a liter of powerade thinned with water.  And a coke.  Couldn't get ice cubes.  Which I regretted.  I soaked my head and hten the shoulders of my jersey.

Basically, from that point on, I stopped and refilled and soaked every hour.  The Osmo packets were for when I could only find a spigot.

I realized that ice cubes make a huge difference in terms of keeping the drinking happy.

Outside of Buchanan, NY, I saw a diner, thought to go in, and didn't.  Regret.  The next time I saw a diner, I resolved to go in.  Luckily a bar came first.  Got two bottles of ice from them (pro tip: people like helping crazy when it walks into their bar), and then went down the street for a liter of Gatorade.  Then it was about an Hour to Tarrytown, where I used the ice machine at a 7-11.  MMMMMMMMnnnnnn.

Keep filling with ice when you can.  'Uuuge difference.

Overally, happy with the survival tactics.  I need to find another bar that goes down well in the heat, as I wasn't happy with the second Clif.  

This is basically a route I've done several times now.  My riding time was 35 minutes slower than last year.  There was more climbing this year, but only an extra mile or two of riding.  There was a headwind much of the way south, which got stiffer as time went on, but I think, I hope that the heat was the culprit.  

And the salt stains were epic.
We're in the middle of a heat wave right now (let's re-read that in January and remember it with envy!) and riding in the heat means you need to take a lot of precautions.
There's great advice in this thread, and searching online brings up a ton more.
The basics are drink a lot more than you normally do, and plan where to refill your bottles.  In this kind of heat,  where the index is 100+, you shouldn't have plain water in your bottles.  There are great sports mixes out there that try to load you back up with vitamins and electrolytes (salts).  No gatorade, since that stuff is poison.  RedBeard carries Scratch, I stick with Hammer, GNC carries mixes, and whatever works for you.
Do be sure to try anything new in your livingroom first.  The last thing you want is to find out, in the middle of River Road in 90 degrees, that your new sports mix gives you a stomach ache.
And knowing you're going to be riding in the heat tomorrow gives you a chance to have sports drinks the night before, topping off your system for the next day.
Do remember to use sun block, and on days like these, I carry a small tube with me to reapply when I stop to fill my bottles, since I sweat it all off me.
Companies sell sun sleeves for your arms.  I haven't seen many people use them, but know they're out there. 
It's going to be hot on the road, so your tire pressure will go up.  Keep this in mind when putting air in, that you don't have to ride with it as high as you normally do so you can try and avoid blowouts.
Your rims and discs will heat up faster, making your braking slower, so give yourself extra time to slow, and don't ride super fast in this weather, anyway.
Whatever your training plan says, this is one of those times to ride slowly and take it easy.  There will be time to ride hard and sprint later.

Know the signs for Heat Exhaustion, for you, and in others:
Extra sweating
Bonking and weakness
Lightheadedness and loss of coordination
Nausea and vomiting
I've had heat exhaustion a couple of times and it's terrible.  Mine starts with chills through my body and my arm hairs standing up.  I know now, when that happens, I have to get off the bike and sit in some shade immediately and drink a lot.
One time, once home, I cranked up my AC, applied wet towels to my body and drank a ton of ice water, but it was too late, I got nauseous, passed out in the bathroom and lay on the tile for about 20 minutes waiting for the black and purple dots to swim out of my vision.
You can prevent this by drinking a lot, not exerting on rides at all, riding shorter distances or not riding, and getting off your bike at the first sign.
If this happens when you're in a group, tell someone.  If you see someone with these signs, ask him to get off his bike and take a break.
Heat Exhaustion can lead to Heat Stroke, so definitely take care of yourself, because both of these are serious medical issues.
I love riding in the heat, feeling the thick air surrounding me, and all of the runners in the park glistening with their efforts, going through bottles, the skill of avoiding my top tube when sweat is dripping off my nose, and seeing the temperature on Strava; my fingers permanently pruned because they're soaked, the extra care I have to take so they don't slip on the brake levers.
But it's dangerous and the heat needs to be treated with respect.  Be safe out there.
Great advice Bruce.

Watch yourselves out there - people get more wobbly - don't let yourself get crashed out by someone else's failure to deal with the heat.
Thanks Bruce
Bruce,
       I should have checked this thread before I went out...at 1pm today.  Good thing I remembered much of my own advice.  I did, however, start doing my 'planned' ride of short, steep hills in Yonkers.  On the fourth effort, I decided it was too hot.  

     The goose bumps phenomenon, at least for me, is more of a warning that heat exhaustion is on the near horizon, but, at the same time, it's a sign of trouble.  I find that if I'm experiencing this, I better get some liquids in me and do my best to cool my body down immediately.  If not, time before heat exhaustion is running out quickly.  

     On the plus side, it makes the days when it's in the low-90s feel much milder.
For all the negatives of riding in the heat, there are some positives.

increased blood plasma volume, the body retains more salt, and you mentally acclimate.

*BUMP*

To go along with @JohnOlsson's post on Slack yesterday, with the hot weather here, and summer coming at us quickly, there is a lot of good and valuable info and advice to make riding in the heat more enjoyable and most importantly, safer.
Probably the wrong thread but... https://www.cbc.ca/news/canada/heat-training-athletes-1.6090826

The resale value on this vs the pill unit would be worth it alone. 
In the simple, small advice front...

Lately, on hot days, when just hanging out, after drinking about two liters of water, I switch to Nuun tablets, on the concern that too much water (hyponatrenia) might not be so good for me.

I know it's not hot today, but on Saturday, after the race, I went out for lunch on Pier i, and stayed there for about five hours, sipping on water the whole time.  When I got home, I was still thirsty, and added Nuun to water and quickly chugged a half a liter down.

This came up on Sunday, and I found I'm not the only one doing this.  I think Brian M is now doing this the day before an anticipated long, hot ride.  
After races or once home from a big effort, I too add nuun tablet (usually a half) to my water bottle, and drink it while I take care of whatever, shower, food etc...

Yesterday went on a run after Matt's bday ride, left the bottle w/ nun in the fridge, so it was nice and cold when I got back. 
^definitely an improvement over straight water. Think about it this way - unless you can stomach a drink that is the salinity of blood (ever bit your lip, or put a sliced finger in your mouth?) pretty much anything you drink will be diluting to some degree. It's all a battle to minimize.

It is very hard to "preload" salt because if your kidneys are healthy you'll piss it out very quickly.
I used to follow the full Osmo suite when we were sponsored and I was racing every week and training pretty hard. It including the preload + post and it definitely felt like it was working compared to straight water. Then again I switched to powdered gatorade after I ran out of the during/post packets and think that worked just as well for the level of training/racing I was doing at the time.
It's been so humid lately that the sweat in the eyes/glasses thing has become a drag. I found a great hack though: A dollop of Aquaphor in the middle of forehead then smear it down in a line so it intersects with the end of your eyebrows like a chevron ^ . Pluses are, it's easy, it works for a good hour at least and it's inexpensive. Minuses are it just takes an errant wipe to destroy said sweat protection.
That's a great little hack I'll have to try. I've been wearing frameless glasses on especially humid days lately. Since the sweat can roll right off and not get caught on the frame, they stay less disgusting and salty for longer
