Steve Diederich
Founder and Managing Director

Steve is the leader and founder of our tribe and is passionate about ultras. Steve is a marketing professional who has worked in a variety of Marketing Director roles in the UK travel industry including Thomas Cook, Kuoni, Travelzest and Sunmed.

If Steve is not out leading events for runners he's planning other ones and is an active member and mover and shaker of the ultra running global community.

Steve's vision drives us forward and his role and primary goal is to support the team to deliver the best possible experience for our RunUltra members and race organisers. 

RunUltra represents the UK, Ireland and South Africa for one of the toughest foot races on the planet, the legendary Marathon Des Sables (Sahara). The company also represents The Coastal Challenge (Costa Rica), the Everest Trail Race (Nepal) and The Namibian Crossing (South Africa/Namibia) in the UK.

Sarah Cooke
Social Community & Event Listings Manager

Sarah plays a key role in supporting our social team to network and build relationships with runners via our social channels. She also manages our race listings and communication with race organisers.

Sarah is a clinical psychologist who has worked in the NHS for a number of years. During her training, she worked with people of all ages with a wide range of mental and physical health and learning needs. She also writes psychology-based articles for Run Ultra and is a qualified running coach.

Here are a few words from Sarah:

Since qualifying, I have specialised in working with teenagers and young adults with complex mental health difficulties. I have recently left the NHS and am excited to be pursuing new challenges, combining psychology with my love of running.”

I started running in 2013 and discovered my love of the trails and longer distances in 2014/15.
