I have been using these energy mixes for quite a while and i wont use anything else they keep you going on long cycles more especially i tend to start drinking it about ten minutes before the ride and i use two bottles over three hours some people may differ but cant but recommend these sachets plus great value

This product has helped me through many 50+ mile rides.
I have just stocked back up with these and would recommend this product, and other high5 products to anyone.
The berry doesn't taste brilliant when you first try it before your ride, but once out, it tastes better than any other product I have tried in the past.

Have used this product on long ride with other electrolite products. Found it to be pleasant to taste (summer fruits) and quite filling. Didn't run out of energy and wasn't hugry either. Good combination when used with other High5 products.

I have until recently been a water only drinker, but the problem was I had reached a platue in performance. I was pushing hard and feeling ill because of the exertion, but no longer feeling burning muscles! On the recommendation of other reviews I decided to try this out. It is outstanding. You can mix a sachet with 500ml or 750ml. I chose the 750ml dilution and rode my regular trails. I passed my first burnout point with no ill effects and rode the rest of the route with loads more energy...and the best is I could feel my muscles had been worked, a bit stiff the next morning. Also, no more beginnings of leg cramping!! You can't go wrong with this.

Rated 5 out of 5 by Anonymous Best I've tried
Tried this and other drinks, including water, on repeat rides of the same route. Water left me feeling drained, Weider stuff was better than water, Lucozade sport was OK, SIS electrolyte was good, but this was the best. Easy on the stomach and despite riding hard I still felt up for further training once I got home. Great for longer rides and between rides recovery.

Rated 5 out of 5 by Anonymous Works really well.
A tad expensive but works really well. Flavour is ok I suppose, bearable anyway. Leaves the teeth a bit furry at the end of the day but that can be tolerated when you get the performance. If I just drink water on long rides I’m forever jumping off the bike for a slash, and a few hours in start to feel drained, but not when I use this stuff. I would use it more if it didn’t cost somuch, but it is cheaper than anywhere on CRC.
