Rider Fatigue

[bwizz]

Thanks all  , Just as aside I think this isotonic hydration theory was discovered after early 20th century war , where soldiers were dying from Cholera associated dehydration.
When i was doing a lot of sports cycling some years ago I used a product called Isostar
it was very good and nice tasting , but harsh on teeth.
Thanks for offer manuel 32 , If you give me yer poscode (By private message if necessary)
I will keep it as a option
