Progressive Distance Challenge

Five rides across the year, each increasing in length, from 40 km up to 200 km, allowing riders to steadily build strength and confidence.

Fully Supported Open-Road Riding

reviews

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.

RiderGrand Slam 2025

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.

RiderGrand Slam 2025

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.

RiderGrand Slam 2025

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.
