Your introduction to the world of extreme triathlons

The Knysna Extreme 0.5 is a shorter alternative to the Knysna Extreme Triathlon and serves as an introduction to the world of extreme triathlons. With an altitude gain of nearly 1,700m over a total distance of 132.50 km, the Knysna Extreme 0.5 offers an exciting challenge for athletes.

The course starts with a 2.5 km swim in the Knysna Estuary, followed by a 100 km cycle through the Garden Route. The 30 km run takes you into the Knysna forest and to the finish line at Diepwalle Forrest Station.

It is not mandatory for Knysna Extreme 0.5 athletes to have a supporter to follow them throughout the race. However, supporters are more than welcome to be part of the journey. Knysna Extreme 0.5 athletes are allowed to have a supporter follow them on the cycle leg (via vehicle) or second them on the run leg of the race – on foot, mountain bike or vehicle.

​I have never in my life, in as many events as I have competed in, bent over with my hands on my knees looked at the ground and said “I can’t, I just can’t” – but I did. How I do not know. Some Winston Churchill “Never, ever give up” vasbyt me thinks.

I have been racing for many years and done almost all of the big local races several times. I have also raced over seas but can still comfortably say that the Knysna Extreme is hands down the most breathtakingly beautiful race I have ever done! 
The unique format makes it a really special day with your supporters and not only playing a crucial role in getting you through the day but also being able to experience, first hand from start to finish. There is no other race that allows that. It almost make you forget how blindly hard the run course is!!

Athlete #119 - Matthew Franzsen

Toughest and most beautiful event I’ve ever done, pushing your limits to the fullest in every aspect! Love the fact that you can have a support vehicle and share this incredible experience with your loved ones

Athlete #116 - Rhyk Welgemoed

Living up to its name the Extreme embodies the ultimate triathlon.
Taking me beyond my limits and proving to me what my body is capable of if I am into it mind, body and soul.

Knysna Extreme 0.5 will challenge any ultra-triathlete across all three disciplines. An exhilarating experience from start to finish.  The supporters are magical; their presence is crucial, as they keep you motivated and moving forward.  A truly humbling experience indeed. Knysna Extreme 0.5 is impeccably organized and lives up to its name! 

Athlete #108 - Lesley-Ann Bush

The Knysna Extreme lives up to its name, tough and scenically stunning. We competed in the Knysna Extreme 0.5 as a family team, and was a fantastic experience. All three disciplines where tough and testing, and what better environment to do it in than the scenic garden route area of Knysna and the Wilderness. Would strongly recommend it to anyone looking for the next step up.

“The Knysna Extreme Triathlon is one of the toughest, but most picturesque triathlons in Africa. 

4 of the PSM athletes took part in the event last weekend, each of them absolutely mind blown by the incredible experience that it was. There were many “pinch yourself” moments during the course. A race, really, like no other. A race, which gives “post-race blues” it’s real meaning. 

Athlete #121 - Nicky Smith

As a new comer to triathlons I didn't know what to expect . I can surely say it wasn't easy the event challenged me on every single level and made me stronger and want to come back for more .
