First day of the current warm spell I got the worst sunburn on my life in the Dales
100km+ on my mtb in vest, I was out for a good 8 hours in the heat, creamless
How do you lot who drink bottles and bottles of water actually manage to get it down your neck? Where do you put it?
It pours through my skin at a rate that some find incredible to observe. And thus clearly moves out of my stomach pretty rapidly.
It's clear I'm cold weather adapted/run hot. In the dead of winter I wear a windproof and summer t-shirt, whilst everyone else is wearing another two layers.
In summer, dumping my heat is the key factor for how I feel and how well I can exercise.
12 degrees is t-shirt weather. 16 degrees is shirt off. 20 degrees is riding in flip-flops. 25 degrees is no ride without a lake to jump in at some point.
What does everyone do on their on-trend Enduro bikes with one bottle cage? That’s nowhere near enough in hot weather. I’m a Camelbak user and proud of it
the problem with a camelbak when it is hot is the lack of ventilation. they trap too much heat for my taste.
when i lived in texas i wore the thinnest lycra in the lightest colours that i could find with a coating of facto 50 cream. it was ok on the move, but waiting at red lights was very uncomfortable.

Carry a bottle with a built in water filter and fill up on the go.
FWIW Garmin calculates sweat loss and it seems pretty accurate if you weigh yourself before and after a ride or run. IIRC, Saturdays 23km run was about 2.5 litres.

That's been me since I was a child, my mother used to say the handles on my cutlery was twice the temp of anyone else’s when clearing the table. I used to get called the honorary Geordie when visiting our site in Newcastle in the dead of winter with a Tee shirt as my only top layer!
I also suffer terrible sinus headaches from exercise in hot weather as a result of a head injury following a hit & run 🙁
To answer the question, no issue riding in the heat. Running on the other hand is an issue with anything remotely warm.
This
Did a long ride at the weekend 27 degrees, was only too hot when we stopped for a break. Drank 5l of water.
Cant run in anything over 17 degrees though
Those hot days I rode thru I was drinking 6 l every day plus more in the evenings
What does that mean? I keep getting told its better for you to drink lots, but I have no idea how/why to drink if I’m not actually thirsty. What’s the trigger for “I know what, I’ll have a drink”?
When you get thirsty. We used to have a contributor on here for whom this stuff literally was his job. Your body has a very good way of regulating body fluid volume. Its called thirst. In the UK at normal UK summer temps I can ride all day on a litre no issues at all. Been out today for 5 hours. Half a litre plus another half when I got back
You can tell when you run low on electrolytes 'cos you drink and immediately pee it out but are still thirsty. Last summer I needed to have electrolytes but normally I do not
Everyone varies but there is this compulsion to drink more than is needed. the 2L a day recommendation for example is not really based on anything very much
This evening's temperature was spot on for my commute, and the roads were really quiet for some reason. Quieter than during school holidays. It was weird but very welcome.
How do you lot who drink bottles and bottles of water actually manage to get it down your neck? Where do you put it?
I don’t normally drink much (on mild days I used to ride for 3 hours without drinking) but I’ve had at least one day where I’ve drunk a dozen large bottles and still barely needed to pee. I do a good line in sweating.
But I can take the heat if it’s heat alone; multiple times I’ve ridden in over 40 degrees and not been unhappy. Turn up the humidity, though, and I start to fall apart rapidly.

Rather like with hunger and modern diets, I am not sure everyone has a natural thirst response.
Went out yesterday morning around Ilkley Moor and must admit that it bashed me for the rest of the day even though I didn't go too far. Only took one bottle though.
In my experience there's a difference between managing without enough fluids and performing without enough fluids. I can (and often do) ride for a long time without needing to constantly top up but speed/power drop off markedly. In my case it's probably more noticeable when running than it is when riding, due to the higher intensity of exercise.

Add humidity into the equation. I find high humidity more debilitating than absolute temperature
Pretty much this for me, i can live with it being in the 30s, but in the UK we tend to have high humidity as well, which is why it always feels warmer than drier climates, was out the other day before the thunder storms and it felt dense and not very comfortable after a while, went out today and it felt fine and easy, temperature you can mitigate in some ways, humidity is just a pain to deal with.
I'm made for cooler climates.
I had planned for a ride on Monday but the youngest has a tummy bug, so I was on daddy duty and to be honest I would of struggled in that heat.
The factory I work in would of been horrendous these last few days, easily high 30s. Hotter up on the mezzanine.
I find the heat fine but add in some high humidity and I really suffer
the 2L a day recommendation for example is not really based on anything very much
IIRC it's based on a study that analysed how much moisture the subjects breathed out, and concluded that they needed to take in that amount, which was about two litres. But they pointed out that much of that water cames from the food we eat, you don't have to drink 2l of water on top of that.
In the UK at normal UK summer temps I can ride all day on a litre no issues at all.
I on the other hand rode 3.5hs on Sunday with 1l of drink and I was thirsty as hell and felt pretty bad.
I'm in the sub-tropics. In the summer it's often mid-20s for a sunrise ride and incredibly humid. It's taken me years to adapt as i'm a walking sauna. I get laughed at because I have to wring my clothes out at the end of the ride.
In the winter it's mid-20s in the middle of the day but not as humid.
Took a Scottish lad for a 2-hour ride in January once and warned him to pack 1 litre per hour... he couldn't believe it but he needed all of that water. I've knocked back 9 litres in 9 hours before. Weekend before last I got through 4.5 litres on a 55km singletrack ride.
My tips are:
- out in the open, wear a loose thin long sleeve shirt and collar - protects the skin and helps cool it too
- avoid a backpack if possible - that heats me up more than anything (5 degrees this morning and my t-shirt is soaked because of my backpack)
- have a bottle with electrolytes in.
Even worse is trail biking on a moto. Slow speeds and all the gear can be dangerous. I've given electrolytes to other riders a couple of times when they've started to spin out or cramp. A while back a local lad died from heatstroke when he broke down in the woods.
6 months of the year, WFH, I’ll happily go from breakfast (glass of OJ, double espresso) to tea time at 6pm with no liquid passing my lips. Just never something I think about. Better now the OH is also WFH as she wants a post lunch coffee…
Don’t get headaches; wee is normal in volume and colour
I work with people that barely drink anything all day, whilst I'm drinking my 2l water. I don't know how they do it, I'd feel like crap, but everyone is different I suppose.
I'd rather carry on with the premise that I'm keeping my organs hydrated and my body flushed through of toxins though
Cherish the current weather. It could be non stop rain all summer.
