H2Pro Hydrate at the Patrouille Des Glaciers

Thursday, May 10, 2022

The Patrouille Des Glaciers (PDG) is one of the worlds toughest ski mountaineering races. Held every 2 years in the Alps near Zermatt, Switzerland it is an event with military origins and in 2012 a group of British soldiers headed out to take on the challenge - using H2Pro Hydrate to keep their fluids and electrolytes topped up in a very harsh, unforgiving environment. This is what they had to say about their experience:

"Despite having limited time to prepare we used H2Pro during the flight to Switzerland 48hrs prior to the race which undoubtably helped with our basic hydration. During our training day before the race we tested the race concentration to confirm suitability. Not only did the product keep us hydrated during a long and arduous day but I'm convinced it helped us adjust to the altitude and acclimatise quicker. Although the race was stopped due to avalanches I am sure H2Pro mitigated our lack of environmental training and acclimatisation."

Hydration at high altitude can be an issue due to the dryness of the air and sweat losses whilst ski mountaineering can be very high as it requires a lot of clothing to be worn to protect against the elements yet work rates are very high. Having H2Pro Hydrate in the water they were carrying also helped to stop it freezing up in sub zero temperatures.

We will be supporting the British team in 2 years time when they will get a second chance to take on the PDG - hopefully this time without the avalanche risk that cut this years race short.

The Ultimate Sport Drink? Possibly not.....

Tuesday, April 24, 2022

We were interested to read an announcement that someone in the US has created the "ultimate sports drink" with its own spin on the ideal electrolyte mix


This time, the EX5 drink puts in a much higher level of potassium than seen in most sports drink - in fact 7x higher than Gatorade and almost 9x higher than Powerade.  It's an interesting concept because unlike appropriate sodium supplementation, nowhere in the scientific literature has it ever been demonstrated that potassium supplementation in sports hydration confers any benefit.

What's more, average sweat losses of potassium are 150 mmol/L so it would take around 16 litres of sweat to become potassium deficient and that's not likely to happen in a typical training session or race no matter how hot it is if you're eating a regular diet.  We're not really big believers in this one.......not with a potassium load that high and a sodium load of only 5 mmol/L.  The lowest sodium loss we've tested in over 300 tests done in house on athletes is 19 mmol/L so there is no way EX5 will replace losses of the lowest salt sweater....
