Recommended products

  • The HIGH5 Run Pack contains all the key products you need for race day. If you haven’t already got a belt to carry your gels, then make sure you add the Race Belt to your bundle – it’s designed to hold HIGH5 gels.
  • With key electrolytes, sodium, potassium and magnesium, ZERO gives you what water can’t. One tablet of ZERO Caffeine Hit also contains 75mg of caffeine, about the same amount as in a cup of coffee. When taking part in a half marathon, caffeine contributes to an increase in endurance performance and capacity. That means you can go further than before!
  • This gel is great for an extra edge before and during your training session or race. Each sachet  of Energy Gel Aqua Caffeine Hit delivers 23g of carbohydrate energy and it also contains a high dose of caffeine (100mg). Just like with ZERO Caffeine Hit, this has a positive impact on your endurance performance and capacity.
