2023.10.28 Dirty Chill

Fun – Social – Learning – Adventure Ride

Held on the same day as the Epic Dirty Challenges the Dirty Chill give riders a taste of the more adventurous side of cycling and what a DirtyClean Challenge is. We want you to have fun, make new friends and to experience the essence of what adventuring with a bike to new places is all about.

The Dirty Chill rides are guided, supported and are 50km long.

You will go through little villages, push your bike a little over mountain hills, stop for a picnic and coffee in a traditional village building, try some stepper hill sections and can easily cut it short if the 50km 3h rides is too long for you!

You need flat shoes or mountain bike shoes, cycling pants and a jersey or t-shirt. Helmets are required (we have some you can borrow but best to bring your own).

From a bike perspective a gravel bike is best but mountain bikes or any bike with fat tires and lots of gears work well. We have bikes to rent if you dont have a suitable bike.  

We also have some ebikes to rent which are great for this type of adventure!
