Meet Julia Andersen, endurance sports nut and mum to a 5-year-old daughter. A former GB Masters swimming record-holder, Julia discovered swimrun after her daughter was born and competes as a mixed pair with her husband, Martin. Together they’ve been crowned Breca Swimrun Sprint champions and last year finished the notoriously tough Ötillö World Championship – a mad combination of 6 miles of swimming and 40 miles of technical trail running.

With an impressive talent for endurance, Julia has enjoyed wins in triathlon, aquathlon, open water swimming and swimrun. Below, the 36-year-old tells me where it all started.
