I am on my first pack of these now and did consistent ride  43   miles  in the heat on the Cornwall hills  today, these proved excellent. Dissolved 2 tabs in 1 litre and 1 tab in half a litre bottles and headed out. They kept me going brilliantly and did feel a difference with the boost of caffeine over the normal hydro tabs. Kept some tabs on me for additional water stops. The taste is acceptable even when warm, a bit like flat coke. I didn't rely solely on these for the entire ride as I packed a peanut butter and jam bagel too so don't think these alone will substitute some carbs whilst out. I will buy these again.

tastes nice and is easy to carry with you on long rides. very good value for money too ( 1x 20 tablets) £3.75 go on
