Mike Finch's Severe Cramps Story
- Mike Finch shared his worst cramp experience during a duathlon where both calves cramped fully mid-bike.

- Exercise-associated muscle cramps (EAMCs) are idiopathic and idiosyncratic, meaning causes vary and cannot be precisely predicted.

- The nerve impulse originates at the spinal level, not the muscle itself.
