Thousands of athletes began the 99th edition of the Comrades Marathon on Sunday, running from Durban to Pietermaritzburg [1].

As the world's oldest and largest ultramarathon, the event represents a significant cultural milestone in South African athletics and provides a substantial economic injection into the KwaZulu-Natal region.

The race started at 5 a.m. [2]. A total of 21,633 registered runners [3] entered the competition, which covers a distance of 85.777 km [1]. Participants must complete the course within a strict 12-hour time limit [1] to earn their medals.

Defending champions Piet Wiersma and Gerda Steyn returned to the race as favorites [2]. The route concludes at the Scottsville Racecourse in Pietermaritzburg [2]. The event alternates between "up" and "down" runs annually to maintain its historic tradition [1].

Beyond the athletic competition, the marathon serves as a major financial driver. The annual economic footprint of the event is close to R1 billion [4]. This financial impact is amplified during the long weekend, benefiting local businesses, and tourism sectors in Durban and surrounding areas [4].

The 99th edition of the Comrades Marathon is known as 'The Ultimate Human Race'.

The proximity of the 99th edition signals the approach of the centenary milestone for the Comrades Marathon. The event's ability to maintain a field of over 21,000 participants and a billion-rand economic impact demonstrates its enduring status as both a premier sporting event and a critical piece of regional economic infrastructure in South Africa.
