Probably one of the most punishing challenges you can put your body through, triathlons require everything from their participants. You need speed and strength - but over hours rather than minutes and across a range of disciplines. So we recommend products to get you in the best condition in your training period but also to keep you going on the day. Hydration needs to be spot on throughout and afterwards, and because this is an exhausting sport you need to make sure you replenish your body well afterwards, something many people find is best done through liquids rather than foods which can prove too much for the body to take. Your immunity will also plummet so make sure you keep your vitamin, amino acid and antioxidant levels high.
