Siân Longthorpe is based in the South West of England and has been a keen runner since a young teenager. Siân was assigned male at birth, and while living as Simon, developed a passion for running, everything from 5k up to ultra marathon distances, winning and podiuming many races. Siân transitioned from male to female and while her life was turned on it's head during that time, running has been an anchor throughout. 

Siân openly discusses her life as Simon, the physiological and psychological aspects of transitioning, as well as acceptance and empowering others in the running community.

Siân is part of the Asics FrontRunner Team and you can find out more about her and read her blog here.
