Hi I'm Sophie Power (@ultra_sophie).  I'm an ultrarunner, mum of 3 and passionate about breaking down barriers to women in sport.  As well as finding my own limits

I'm going to be running on a treadmill for 48 hours live at the National Running Show to raise funds for SheRACES - but also hopefully inspire more women to take on their own challenge.

SheRACES advocates for women in sport - conducting research and then working with events globally to make them better for women.  From pregnancy deferrals, to t-shirts that fit, period products and having the women's race properly highlighted.  Simple changes make a huge difference and we've made start lines better for women around the world.  We'd love to get more women on start lines so please support us!

Please donate if you can - and come and join me on the treadmill if you are at the show!
