Sanna Duthie
Being outdoors is where I love to be, so if I can spend literally a day or more outside in the mountains running 100 miles I am happy. I have been running ultras since 2015 and I love the people I meet during running and via social media. I have used my running to raise money for charity over the years raising over £10,000. I love talking and sharing my experiences outdoors. Running has helped me mentally and I hope that through sharing my journey that I can help others.

Fiona Cook
Fiona has been into fitness since her early 20s in a bid to lose weight, but only seriously took up running at the age of 35 after the birth of her daughter. Buggy running made up the majority of her miles and road marathons became the focus.
After successfully breaking the 3 hour marathon multiple times, she switched her focus to ultras after realising that this was her niche. 2025 was her first serious year of ultras, seeing her take 4 podium places along with a win at the Tour of Merseyside.
As a dietitian, Fiona takes nutrition seriously and is always keen to help guide others with their training and race day fuelling. She can also be found offering help to fellow ultra runners in any way she can.
Its a huge honour for Fiona to be part of such a great team and hopes to be able to continue her success moving forward.
