South African running is built on giants — the Comrades Marathon (~90km between Durban and Pietermaritzburg) is the world's largest ultramarathon, and the Two Oceans (56km) in Cape Town is close behind, while the Cape Town Marathon now carries a World Athletics gold label. Trail running is world-class: Ultra-trail Cape Town, the Otter African Trail Run along the Garden Route, and deep Drakensberg and Table Mountain scenes. Cycling is equally serious — the Cape Town Cycle Tour (~109km) is the world's largest timed road race, the Absa Cape Epic is mountain biking's premier stage race, and the 94.7 Cycle Challenge anchors Johannesburg. Triathlon runs on IRONMAN South Africa in Gqeberha (Port Elizabeth) and 70.3 races in Durban and Mossel Bay.
