High 5 Energy Source Extreme

What’s in your water? Now that everyone’s on board with the importance of staying hydrated in the saddle, the question of additives is the next conundrum. Is plain water enough? Well, the powder people would have you believe not - you need your electrolytes to get the best possible uptake of H2O into your  bloodstream.

If you’re a traditionalist or sceptic, you’ll note  that there are electrolytes aplenty in traditional foods like crisps, peanuts and bananas. But they may not have the optimum quantity and balance to keep you hydrated and there’s a certain convenience in having the magic ions predissolved in the drinks bottle.

I’ve been testing a number of products this year and the one I liked best was High Five’s Energy Source Xtreme with added caffeine power. I used it during a big road day in the Peak this summer when the sun beat down with uncharacteristic ferocity on the tarmac of Holme Moss and The Snake. The magic potion saw me holding up over a tough day without any of the sudden spikes and drops you can get from over-sugary products.

Because this is powerful stuff, we’re deep into “Read  the Label” territory. Here are the caveats from the High Five Website:


X’treme is not intended for continuous use during training or an event. Excessive amounts of caffeine can lead to side effects like headache, dizziness and gastrointestinal distress. If you wish to use caffeine continuously throughout your training or event, then switch to EnergySource Plus, which has considerably lower caffeine content (60mg/L). Very occasionally some athletes find that caffeine can increase cramp, so always try in training before racing. If there is a problem then switch to standard EnergySource.

However, if you do read the label, and you're after something to get you those extra miles whilst feeling fine, then this could be just the juice for you. It tastes okay and does exactly what it says...even with the caffiene!

Overall then, it's a 4 out of 5 for High Five, who continue to make good products for cyclists; but don't just take our word for it...try it.
