In just a handful of editions, it’s cemented its status as one of South Africa’s most prestigious – and brutally honest – marathon mountain bike races. If you want a true measure of where you stand as a rider in 2026, this is it. Here are five reasons why the Big 5 deserves your entry.

- The ultimate Cape Epic form check
There are few races that tell the truth like the Big 5. At 77km with 3000m of climbing, it’s one of the most reliable indicators of Absa Cape Epic readiness you’ll find anywhere. The sustained climbs, high-speed descents, and relentless demand on both body and mind mirror exactly what awaits in March. If you can manage the Big 5, you’re on the right track. If it exposes weaknesses – even better. That’s valuable information.

- A marathon in name. An ultra in execution.
Yes, it’s “only” 77km. But the elevation gain rewrites the script. With five major climbs stacked into a single, uncompromising route, this is an ultra-marathon effort masquerading as a marathon distance. Pacing, nutrition, and mental resilience matter just as much as raw power. There are no shortcuts – just the work.

- Five climbs. One distance. Zero compromise.
The Big 5 is named for the five defining climbs that shape the race – and your day. There’s only one distance and no half measures. Every rider takes on the same challenge, from the front of the race to the final finisher. Add to that a strict no eBikes policy, and what you get is a pure, old-school test of all-round mountain biking ability: fitness, skill, grit, and race craft.

- Descents that demand respect
Whatever you gain on the climbs can disappear in seconds if you switch off on the way down. Cliffhanger may be the headline act, but every descent on this course requires full commitment and control. This is technical, consequence-filled mountain biking, where skill matters as much as strength – and where confidence is earned, not gifted.

- A start line with serious credibility
The Big 5 MTB Challenge consistently attracts South Africa’s best, alongside some of the strongest international riders in the sport. When a multiple-time World Champion like Nino Schurter has lined up here, you know this is more than just another marathon. It’s a race that carries weight – and finishing it means something.

Taking place on Saturday, 21 February 2026, the Big 5 MTB Challenge, presented by Imbuko and Canetsfontein, is widely regarded as the ultimate one-day mountain bike race in South Africa. Entries are still available, but this isn’t about filling a gap in your calendar. It’s about finding out exactly what kind of rider you are – and whether you’re ready for what comes next.
