At What The Fartlek we have had the absolute honour of working with, interviewing and meeting some of the incredible businesses that make up an integral part of our running community.

We take great pride in supporting and promoting brands, products and companies that we truly believe in and have struck up some great relationships as a result of this.

Below is a list of some of the great teams out there that we think you should check out (there are even a few cheeky discounts thrown in there if you tell them we sent you).

Twisted Running are the home of all our latest WTF merchandise needs.  Their team of designers create t-shirt designs that capture the essence of a brand and leave lasting impressions through eye-catching logos and vibrant graphics.   

Their state of the art printing technology and premium materials ensure that each item has crisp colours, sharp lines and feels amazing.

Check out their website to check out their ranges and our awesome merchandise and use the code WTF10 at checkout to get 10% off.


Runderwear are our official 'performance underwear partner of choice' at WTF.  They have a simple mission statement - to liberate runners from chafing and allow them to focus on what they love to free.  They have just moved their range to 92% recycled material, creating a more eco-conscious and sustainable product for the future.

Check out their website for the smoothest ride of your life and check out our chat with founders Jamie and Rich on the pod here.

We love Rasselbock - the location of our annual January meetup.  Eric and the team put on laid back, inclusive and supportive events at some of the most stunning locations.  Running a Rasselbock event is just like getting a 6 hour hug... in a forest.

Ever wondered what to do with those old race t-shirts?  You know, the sentimental ones that you'll never wear but mean too much to throw out.  Well Medal Munchers can help you create a timeless (and adorable) keepsake to remember your race.  Find out about Morty and the whole gang over on their website now.

Our pals at Coopah are reinventing online run coaching through their interactive, easy to use app based coaching solution.  But its not just about the plan for Coopah, they are building a community of supportive, like minded people all on the road to improving their running.

Coopah have kindly offered Fartlek Family a free month trial of their paid plan using the code WHATTHEFARTLEK via this link:
