How much fluid for 100 miles ?

[Cuchilo]

Just wondering what people would take on a jaunt of this distance ?

Two big water bottles, and a cup of tea at 2/3rds distance, where I might top one of the bottles up.

As the Americans say: your mileage may vary.

Very very temperature dependent.

On rides of longer than 50km, I fill both bottles and refill as necessary. Londis usually have lucozade or oasis or similar on special, mix with a bottle of water, if I can't find somewhere to top up with water.

It's very much weather and exertion dependent.

My consumption falls between two and seven litres.

Depends how long it takes, you should consider such things on a duration basis, not a mileage basis

That's a very good point that I hadn't thought of .

As much as you need, and only you know how much that is.

I know people who would do it on one 750 mL bottle.

Unfit, and overweight, on a hot day, I would probably get through four or five 750 mL bottles. Maybe three when fit and on a cool day.

Think in terms of 500 mL per hour and you will probably be about right.

Weigh yourself before and after rides. If you are significantly lighter than when you set off then you should consider drinking more, 1 litre per kilo lost.

I did 100 miles in 6 and a bit hours yesterday, average temperature was 12 degrees, and I took and drank 2 x 750ml bottles. I drank more after the ride than during it, but that involved alcohol and is the reason I feel rough this morning

I'd echo what others say. If you've got a planned cafe stop then thts a good time to refil. I'd probably go through 3 or 4 750ml bottles.

Was this the Cycle Norfolk Ride? Did this on one 750ml bottle plus copious amounts of freebie energy gels that tasted like washing powder!

And the odd cheeky pint or two of Guinness afterwards.

Hugely weather and exertion dependent. If I could actually find 100 flat miles, I could do it on a cold day with 2 x 750ml bottle. But yesterday I did 60 hard, hilly miles in sunny, still conditions and needed 2.7 litres (I use 900ml bottles and refilled one). So a 100 mile like yesterday would be 4.5 litres....about a gallon !!

 

[vickster]

Probably 2 or 3 bottles and a couple of skinny lattes But depends on the temperature

Have you not done the ton yet?

No, I wish it had been in Norfolk as it might have been a bit flatter!

 

[JasonHolder]

Intensity/duration/food on bike consumption/temp/fitness and start of ride hydration state dependant really. Do you know what you're eating?

I've done 100k on one 750 when it's cool, and 117 miles was more than 4 bottles over last summer. Pity I only had 4 bottles! It was pretty awful at the end!
