True Stryde fuelling tip
It has a strong vinegar taste, so try it in training first. Carry one in your race belt for the last 10km of a marathon.

Keep the lid closed between uses and check the best-before date. Store in a cool, dry place, out of direct sun.

Questions
How does it work?
FIXX says the vinegar triggers a nerve response that switches off the cramp signal, rather than acting on the muscle itself. The causes of cramp aren’t fully understood.
Does it replace electrolytes or water?
No. FIXX says to keep up your normal fluids, carbs and electrolytes.
Who shouldn’t use it?
FIXX says it’s not for pregnant women or children under 15. Check with your doctor first if you take medication.
