Tackle the Bike SA Grand Slam Challenge Series and ride a longer distance with each ride, progressively extending your stamina throughout the year! The 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.
Five rides across the year, each increasing in length, from 40 km up to 200 km, allowing riders to steadily build strength and confidence.
Clear route notes, marked courses, hydration stations, first aid and mechanical backup provide strong support while you ride at your own pace.
A welcoming community event where riders encourage one another, making it ideal for both experienced cyclists and those tackling longer distances for the first time.
From sunrise trail starts to sunset campsite stories - Grand Slam Challenge is a visual journey as much as a physical one.
I’ve done plenty of rides in SA, but the Grand Slam routes are some of the best marked and best supported. Having the option to choose one loop or go for both made it easy to ride at my own pace.
A fantastic series for building confidence. Each Grand Slam gets a little longer, but the structure makes progression feel natural. It’s become a key part of my training calendar.
It’s challenging, but never intimidating.
The atmosphere is always welcoming and organised. Volunteers are supportive, the signage is clear, and the whole day feels smooth from start to finish. It’s the kind of event that keeps you coming back.
Consistently one of the best value rides in SA. Great support, friendly riders, well planned routes, and a real sense of achievement at the finish. It sets the standard for community cycling events.
