Trust me if you live in South Wales and go out for an unplanned cycle seeing Araf and then Slow very scary indeed. Means you are probably near the Mid Wales border!!!!

Nahh that takes the fun out of being in the back of beyond with a diminishing water supply, no food, no phone reception and very tired legs 
Note to self - Put a GPS on my Christmas List!!!!!

Notice only ONE bottle on bike.
That day, I was losing about 4 cm3 H2O per minute. The bottle is 600 cm3, so I had 150 minutes of water. Stops were less than 2 hours apart, so no worries about dehydration and ‘diminishing water supply’.
Incidentally, other riders on the club ride this morning took two bottles of energy drink. We reached the tea room after about 1 hr 40 mins, and they hadn’t touched their bottles. They should realise they are carrying 1.5 kg more than they need.

I was referring to an unintentional 70 miler I did a while back for which I was unprepared. How did you calculate the cubic cm loss of Water? Do you have a highly advanced cycle computer ?

No, not a bike computer.
The body produces 1 cm3 of H2O per every 4 kcals burned.
14.3 kcals per minute for every kW exerted in that minute.
It is not just the kW that goes to the tyre, the total power output includes the body’s own defence against wind chill etc.
I was really belting it that day riding Solihull to Tywyn and back in the hours of daylight, and my calcs said 8 kCals / min. It was a hot day and I was sweating like a pig, so I doubled it for safety.

Oh sorry I asked. Mind you I love the highly mathematical doubling (to be safe) at the end.
Here's praying I never get so immersed in Maths that I forget to enjoy my cycling.
