If she is dyspraxic, the prospect of taking up running would be – at the very least – a great deal more challenging than for someone without the condition.
Most likely though (perhaps in combination with dyspraxia), your friend is suffering from a lack of confidence.
Was she told as a young girl by a mean PE teacher that she had no co-ordination, I wonder?
It’s amazing how these negative labels become the narratives of our lives. If it is this, or some other limiting belief that has resulted in a loss of confidence, then running may be the very activity that could help her rebuild it.
