The powdered drink additives DO work.
I used to only glug water on a trip,usually 2-3 litres but always found myself with a headache or feeling knackered at the end of the day,powders were available but i never used them untill i went on a macretro blast with 'bike food' as the sponsor giving away free bottles and powders.
At the end of the day i felt a hell of a lot better and wasnt knackered for going to the aftermath pub.
Now i swear by them.They obviously do replace lost salts and minerals sweated out during the ride.
On the 'team of #scientists [# read quacks desperate for another research grant] a similar team found that wearing a hat during hot weather doesnt make you overheat.
:shock: Utter tosh.
