"I grew up in the foothills of the Peak District and have always loved being out in the hills. My journey began rambling in Derbyshire with my mum when I was young. It progressed to long distance trail running in the White Peak and more recently fell running in the Dark Peak and beyond.

I became dismayed at the over-commercialisation of trail running. What should be a simple thing to bring a lot of joy was being overrun with extortionately priced 'must have' gear, airbrushed images of elite athletes and hyped-up advertising campaigns.

As someone relatively new to trail running it was difficult to know what was essential and what was a marketing ploy. Also which design features I specifically needed for my trail runs. So I founded a different type of brand for trail runners. One that is built around quality, design and value and without pretence. ​

The concept for Harrier was born from my own desire to have great quality kit that would last a long time. It's about bringing simplicity and fun back to trail running. We provide everything you need and nothing you don't."

Kate Mackenzie, Founder of Harrier


Currently living in Derbyshire and mostly found running around the Peak District trails. Kate is an advocate for keeping it simple and going trail running a lot!

Her club is Pennine Fell Runners where she runs (usually at the back) around the Kinder Scout area of the Dark Peak. She also loves going out with the weekend crew to awesome places such as Dovedale in the White Peak, Mam Tor in the Dark Peak, Glen Coe in Scotland and various bits of the Bob Graham round in the Lake District.

She is England Athletics Leader in Run Fitness (LiRF) qualified and leads friendly trail running groups and beginners fell running sessions.
