Grand Slam Challenge Series

 Tackle the Zen Energy Grand Slam Challenge Series and ride a longer distance with each ride, progressively extending your stamina throughout the year!

The Zen Energy Grand Slam Challenge Series is the perfect vehicle for goal-setting, motivation and fully supported ride security to help you achieve your riding and fitness goals each year. 

With rides starting from 40km or 80km and building to 100km or 200km Grand Slam finales over the five-ride series, you can track your progress, plan your training and achieve all you hoped for and more. 

Grand Slam is a great way to lock in some rides with your friends or to come out and make new friends in a relaxed and supported environment. 

You can vary between the Grand Slam and the Mini Slam distances from one ride to the next or change your mind on the day. The choice – and the challenge – is up to you.
