Endurance Trial Pack

If you have never fuelled a long run, a cycling event or a triathlon properly, you have probably hit the wall at some point and wondered why. The answer is almost always nutrition. The problem is that most athletes do not know which gel format works best for their stomach, their pace or their event duration until they have tried them. This bundle solves that.

The Endurance Trial Pack puts one of each of the five core SiS gel formats into a single bundle so you can test the full range across your training sessions before committing to a race-day fuelling strategy.

SiS GO Isotonic Energy Gel is the world's first true isotonic gel — 22g of fast-release carbohydrate per sachet, no water chase required, gentle on the stomach. The benchmark endurance gel that most athletes start with.

SiS Beta Fuel Gel steps up to 40g of dual-source carbohydrate per sachet in an advanced 1:0.8 maltodextrin to fructose ratio — built for sessions over two hours where carbohydrate intake targets of 80 to 120g per hour become relevant.

SiS GO Energy + Electrolyte Gel combines 22g of fast-release carbohydrate with added electrolytes to replace sweat losses simultaneously — the practical choice for hot weather racing or events where separate hydration is difficult to manage.

SiS GO Energy + Caffeine Gel adds 75mg of caffeine to the standard 22g carbohydrate base — for the mental focus and reduced perceived effort that caffeine provides in the later stages of a race when concentration starts to slip.

SiS BETA Fuel Energy + Nootropics Gel pairs dual-source carbohydrate with a nootropic blend specifically designed to support cognitive performance and decision-making during endurance events — the most advanced gel in the SiS range.

All five are UK-made, Informed-Sport registered, and require no water to take. Try them all. Then build your race-day strategy around what works for you.

Normally LKR 5,095. Bundle price LKR 3,999. You save LKR 1,096.

Use each gel during a separate training session to test how your stomach responds to each format. Take gels every 20 to 30 minutes during sustained effort lasting over 60 minutes. No water is required to take any of these gels. Start with the GO Isotonic for shorter sessions, move to Beta Fuel for sessions over two hours, use the Caffeine gel in the final third of longer efforts, and test the Nootropics gel for events where mental focus is critical. Once you have tested all five, build your race-day fuelling plan around the formats that worked best for you..
