Tuesday it was 92-93F when I went out for my 11 miles. Garmin read up too 100F. It will be that hot again today. There was a benefit to second shift, riding in the morning before the day heated up.

The humidity is what kills me, better then snow though so I'm not complaining.

My experience is this. Keep hydrated, I usually carry two bottles, one gatorade type, one plain water. I try to alternate between them. I also wear a compression style shirt under my jersey as I find that it helps me regulate core temperature better (and prevents nipple chafing). Other than that, I ride/run through the heat as I find that come time for my fall races, I am stronger for it. That said, learn the signs of heat related issues and stop and address them immediately if you see them.

I'd also consider pouring water over your jersey and head when needed to help keep you cool.

Hydrate all day long, do not wait until your riding or just about too... Wear breathable clothes and just pace yourself. Try to ride in well shaded areas if possible, and keep moving... we create our own breeze.

I have found that riding in the heat does not bother me. I stay hydrated and as long as I am moving I feel cool enough, we have dry heat here. However I've not done hard workouts in the heat, if we ever have really hot weather this year I guess I'll find out how that works for me. As a youth it was not a problem but I was not a clyde back then, Perhaps by the heat i'll no longer be a clyde. Hydration is so important as is keeping electrolytes in balance. Acclimation also helps.

I always drink before I ride, i.e. a bottle of water an hour before I head out. I go through a bottle of Gatorade the first hour I am on the bike. Then I continue to drink at that rate until a couple of hours off the bike, but not necessarily Gatorade as it gets to tasting too sweet after a while.

i think hydrating before and after the ride is very important.

My normal trail I ride is pretty much cutting through the mountains and so far I have found 3 springs pouring out right at the trail. First one at mile 4, 2nd one at mile 9 and 3rd that I just found yesterday was at mile 13ish.

I get horrific headaches from the heat even if I stay hydrated. Those springs are a lifesaver to stop at and dunk my head under. I was hesitant to drink from them at first, but then though my grandparents lived in the mountains moving up to their hunting camp full time, no running water. I grew up drinking mountain spring water all my childhood. Now I down my water bottle by mile 4, drink another one at the spring, fill up and drink that for the next 5 miles, etc. I have unlimited water now with only carrying one water bottle.

Water cascaded down from the ceiling at the entrance to the tunnel as well. i stop there and just let it come down on my head when I feel the headache coming on. The headache is usually not until I'm heading back from at least a 2 hour ride.

Northwestrider

Nice, it sounds like you live in a beautiful area to ride, if a bit warm.

I'd rather sweat than freeze, so I have no issues riding in the heat. The key is to stay hydrated, a problem I've had in the past. Now I carry two bottles on any rides over 25 miles (<2 hours). When I'm on the "backwoods" path there's a spring around 10 miles into my ride that comes right off the mountain that I found out was perfectly safe to drink and is always cold.

I get up early and take off around 6:00 to get my daily 12-17 mile ride in before the worst heat of the day. Still, it's so humid here (Middle Tennessee) that I am soaked with sweat before I'm halfway into the ride. I carry two water bottles with ice water. And I take some paper shop towels to wipe the sweat. Then when I get home, I sit on the porch and drink a bottle of lo-cal Gatorade and eat a Clif Bar as I cool down.

Two weeks ago I was riding in 100 degree temps, and I felt fine. In fact, it felt downright chilly on the downhills. Low humidity will do that. I kept well hydrated.

I'm always slower when I ride in heat that high. I rode up our local mountain on Saturday (in the afternoon, great thinking there) and it topped out at about 105 somewhere on that road. I drank ALL of my available water going up the hill (2 x 24oz bottles), so I stopped and refilled them at the base of the hill, drank all of THAT water and stopped at a gas station and refilled them again (and had one of those mexican cokes... mmm yum) and this after drinking tons of water all day long knowing what I was going to do. So that's about 150oz of water for a 46 mile bike ride. That's significantly higher than my average. If I ride the relatively flat route to the beach and back, it's 53 miles and I drink about one and a half to two bottles if it's not super hot out.

It's all relative.

Hi there.

When it gets really hot and humid here I often mount 3 bottle cages on my bike. One mounts on the centre of the handlebars. I then use a Tim Horton's branded Thermos stainless steel bottle in my 2 frame mounted Minoura bottle cages as the cages will expand enough to hold the Thermos. I mount a water bottle in the handlebar cage. I drink from the bar bottle and refill it from time to time with about 1 cup (250 ml) of cold water from the stainless steel bottles. They keep the water COLD for hours which makes the water really refreshing. If I know i'm going to really sweat I'll put a bit of Half n Half (50% sodium an 50% potassium) into one stainless steel bottle. HnH can be bought at most supermarkets. You need the potassium in order to utilize the sodium in the body. Don't use too much or you'll just make yourself more thirsty. And, drink before you're thirsty in order to stay hydrated.

Here in the Midwest we have hot humid heat.... and sometimes the breeze created by cycling makes it feel like being in a turbo-oven (you cook even faster with moving hot air).

I take along two water bottles... and I plan ahead. Riding in the morning or evening can make a big difference. Having a cool-down location (or warm-up in winter) in mind can be a life saver. Just getting out of the sun and into some air conditioning while drinking a cold coke.... can make a life saving difference.

Ice sock. I was skeptical, then I tried it. It's frigging amazing.

Lvlbiker

What is an ice sock?

zonatandem

Have lived in the Sonoran Desert (AZ) for 38 years and am avid cyclist.
Many summers we get 90 days of 100+ degrees.
"Warmest" ride/commute was at 117 degrees; let about 10 PSI out of my tires, wet my bandana and cycling cap and pedaled home mid-day. Bone dry I less than 5 minutes!
Humidity was 2 per cent, heat rising off the pavement got my shoe soles hot and my eyes were burning behind my sunglasses.
Enjoyable? No. Do-able: yes.
Makes the other days of 110 degrees fell c-o-o-l!
Have ridden a century in Maryland at 98 degrees with 98 per cent humidity.
Have also ridden in Michigan at 20 degrees and snowing . . .
I'll take the dry heat anytime!
Pedal on!

Half of a pair of pantyhose or a log white sock. Fill with ice. Put around your neck under your jersey. Enjoy.

Camelbacks are a wonderful thing when riding in the heat. I'm lucky as to where I ride. Most of my riding is on a MUP that has lots of shade and it's near water. Even on really hot days, the MUP isn't too bad.

donalson

I drink a lot but found that in the heat a camelbak held a TON of heat on my back... I do think some of the newer ones have some sort of channels and stuff in the back support to help with that though.

I stick to water bottles on the road and a camelbak for off... but I've learned where the refill stops are on my typical ride routes... running out of water is NOT something I want to deal with.

bikemig 

Have you tried filling the camelbak full of ice? I find it against be very cool on my back when I do. YMMV.

More importantly, the quickest way to cool down is to lower your core body temp by drinking something cold like ice water. Camelbaks rock for that reason alone.

I just don't do well with the heat. Anything over about 85 degrees and I'm just downright uncomfortable. I start getting a headache and stomach cramps any time the weather gets a bit warm. In these temperatures, usually I can do okay in an area with some tree coverage, but right outside in the open, I'm toast within about 15 minutes.

The other night I went for a ride with our club and the weather was about 85, but there was a fairly cool breeze while moving. I didn't do too bad. I went out last night and it was about 87, but there was tree coverage, so that worked out fine. It was humid, but I did okay. After about 11 miles, I started getting uncomfortable, but thankfully that was the end of our ride. We did that ride on mountain bikes. I'm pretty sure I'm going to have to bite the bullet and get a fit, as I get a bit sore on it. I just got a fit on my roadie no Wednesday and it made all the difference in the world. There still need to be a few minor tweaks made, so I have another appointment on the 3rd, but the difference was amazing.

SammyJ 

Ive had no problem, it's still mid 90's when I ride. I am drinking a LOT of water!

donalson

ya it's been a while but in the FL/TX heat it just didn't do much... I've adapted well to the bottle thing on the road though... along with wicking clothing.
