Shiv

Shiv

Runner & Coach

Four years ago, Siobhan was unsure where running could take her. Since then, she’s fallen head over heels for the sport, completing distances from 5km to 100km, and recently placing in the top 2.5% in a half marathon and 1.4% at my most recent world major marathon. Her journey has taught her that no dream is too big when it comes to running.

As a full-time teacher, she knows first-hand the challenges of juggling training with a busy life. She shares an holistic approach with Group Evolution to thrive in every area of her life.
