Monday i didn't ride but a walk to the bike shop had me in a bit of a mess afterwards, heat exhaustion which had me taking to my bed! I was okay a couple of hours later but i was hatted and somewhat slower when i went to the PO!
Today has been overcast and humid but i got around my 110km ride arounf North Somerset with no ill effects, looks like it may be a degree or two cooler hereabouts until the weekend which is good yeah?

Not to derail the thread but as an adjunct to the heat issue frequently comes a drought.
We last has any measurable amount of rain on 23 May when we got 3/4", but today a storm blew up and dropped a 1/4", so we have now had a whopping 1" of rain in the last 7 weeks.
Unfortunately, the 104 degrees expected tomorrow will soon see that off.
Hopefully I will be able to ride maybe 60 miles tomorrow in any case, lots of water laced with NUUN electrolyte tablets and healthy doses of SaltStick capsules should get me through it - plus sandwich biscuits in my 'go to' handlebar pocket.

I took it to mean two biscuits with something in between, like custard creams or Oreos.

Correct. Sandwich biscuits are two pieces of biscuit with cream in the middle. Easy to eat and digest. It is as important to maintain glycogen levels when endurance riding - which means any riding in this heat - as to maintain electrolytes and salt along with water.
I did try sandwich crackers for a while (cheese filled) but they don't digest well and get stuck in the back of my throat.
Dipping into my bag for the biscuits on the move is easy and the taste is nice which reminds me to keep eating and always following that with a slug of water, which is another reminder to keep drinking.

Can you show me any science behind this? I've always focused on water+electrolytes, seems to be the magic wand. I eat a LOT less carbs now than when I started doing long rides (I can easily do 80km fasted, probably further if I had more discipline!)
Like the rest of your approach though

I was going to post a picture of my bike cockpit set-up, but apparently one cannot upload a photo from a PC.

You should be able to. I normally upload form my PC. The forum software does not accept some file extensions, but most picture formats are ok (jpg, bmp. etc.). There is a thread on uploading photos at
viewtopic.php?f=14&t=36594
If you have further trouble, post on the
help subforum with more details, such as the error message, or what happens.

Here it is:
I've laid the packet of sandwich biscuits on one of the aero bar arm rests - the eagle eyed will note they are called sandwich cookies. This is because American's have a great difficulty with the word 'biscuits' so they had to even a much simpler word - hence: 'cookies'.
The 'go to bag' was sourced in Ukraine and has a cut down butter container at the bottom for hygiene purposes.
Since I am on a roll: I decided to show my house:

is that actually a roll or is it a bap, breadcake, cob or some other small baked bread comestible?

I think I might try setting my Garmin to remind me to have a drink. Today return home from an overnight camp I had a coffee for breakfast and rode 30+ laden miles home incl. the steepest climb I've done yet, got home and entire back of shirt sopping wet, had a pee and 1st thought "blood in that?" - there wasn't but despite having 3 full water bottles one in full view the entire ride I'd never even thought of having a drink.

Do that a few times in the heat and you will soon become a convert to paying attention. It worked for me after having to collapse along the side of the road too many times.

Do they still have baps? I used to have them when In Middlesborough - my mother was from there - and near beer. Do they still have Near beer?

Whilst I accept I should be drinking I just don't seem to remember or feel the need but apart from colour of pee it does not seem to cause me other issues. 2019 in the 40℃ heatwave in France I was cycling 40 mile trips doing the same without realising it. In Burma I was spending the day doing 11 miles walks, carrying a full bottle of water to the end without remembering it (only effect was a weird not serious Eustachian tube thing I suffer from when getting dehydrated).
I'd certainly not recommend what I do and what I do is entirely by accident and I keep thinking "must try harder".
