Gravel is in vogue, with stage races like the Garden Route Giro identified as the next frontier in growing and evolving the sport.

When planning the Garden Route Giro, race director Henco Rademeyer, considered how many elements from road and mountain bike stage racing to include in the inaugural multi-day gravel event, and was heavily influenced by a pioneer from South Africa’s industrious past.

We want to showcase the diversity of the Garden Route in the six days of Garden Route Giro racing,” Rademeyer reflected.

“From hosting mountain bike events in the region, we knew which key features resonate with riders. The potential to bring in longer asphalt stretches, over passes or through poorts (the Afrikaans term for a road along the banks of a river, through a narrow valley), excites us tremendously too. It really allows for a fuller showcasing of beautiful features.”

The Bain legacy

As is the case with many passes in the Western Cape, most of the best features of the 2026 Garden Route Giro course will carry the lasting legacy of Thomas Bain.

Of the six major passes or poorts on the route, five were built by South Africa’s most famous road engineer.

The Garcia-, Swartberg-, Prince Alfred’s- and Seven- Passes are all works of Thomas Bain, while Meiring’s Poort was refined by the man whose father, Andrew Geddes Bain, is the country’s next most renowned road builder.

Garcia Pass

Linking the coastal plane with the Klein Karoo to the north, Gacia Pass is a tarmac road which gains 400m in elevation. It features dairy farms and emerald green fields at its southern starting point, and ends in the arid shrub lands of the Klein Karoo. It crosses the Langeberg Mountain range in a saddle, below Sleeping Beauty a formation with the profile resembling the lead character of the fairy tale.

Rooiberg Pass

The only pass on the Garden Route Giro course which was not designed or renewed by Thomas Bain, the Rooiberg Pass, connects Calitzdorp in the north with Van Wyksdorp in the south. Before the formal pass was completed in 1928 the congregations from each of the towns would meet at the summit, weekly, while escorting the Dutch Reform Church minister they shared across the mountains. They placed a stone on the cairn at the highest point, before turning around and descending towards their respective home towns. The impressive size of the pile highlights how overdue the building of Rooiberg Pass was, after more than a century of weekly crossings by horseback.

Swartberg Pass

Along with Prince Alfred’s Pass, Swartberg Pass is arguably Bain’s greatest work. It features splendid examples of the dry-pack stone walling which he used to support the road surface as it traversed valleys within the mountain side. From the south the pass requires riders to conquer 800m of climbing to the summit, at Die Top, 1,580m above sea level. A spectacular descent follows, to Prince Albert, with winding switchbacks hugging the near sheer northern face of the Swartberg Mountains.

Meiring’s Poort

The Poort had a road through it already when the Bains was called upon to solve the problems caused by repeated flooding of the Grootrivier (the Big River). Thomas was just 26 at the time when construction of the road began and the stone splitting technique his father, Andrew Geddes, developed during the building of Meiring’s Poort would prove invaluable over the coming decades. The track the road replaced crossed the river more frequently than the Bains’ design does, but its 25 crossings in 25km is still significant. Where the passes of the Garden Route Giro provide spectacular vistas due to their elevation, the appeal of the poort is the red rock formations of the narrow canyon it follows. The dramatic folds of sandstone turn every traveller through Meiring’s Poort into an avid geologist for, at least, the duration of the trip.

Prince Alfred’s Pass

South Africa’s longest gravel pass might not reach the heights, above sea level, of Swartberg Pass but it more than makes up in terms of the landscape it crosses. Starting in the Langkloof’s orchards it traverses the Outeniqua Mountains in a southerly direction, crossing through sections of mountain fynbos, pine plantations, and Afromontane indigenous forest. The southern reaches of the pass include the habitat of what is said to be the last remaining Knysna forest elephant. This secretive matriarch is rarely spotted, but occasionally her footprints or dung can be found on the final Kom se Pad section of the pass. The deep forest develops its own microclimate too and rain is never far off.

Seven Passes

The final pass of the 2026 route is a series of drops and rises from the Knysna/George coastal plateau to the rivers which, over the millennia, carved deep gorges into the landscape. The individual challenges include Phantom-, Homtini-, Ruigtevlei-, and Karatara- Passes. Due to the nature of the underlying geology, though the length of each pass varies the drop from the plateau to the river crossings are predominantly in the narrow 85-100m range, except for the Homtini Pass which is the longest and most challenging of the Seven Passes. Started in 1867, it took Bains and a series of fellow road engineers 15 years to complete the 75km road. Today it remains gravel in long sections but also features asphalt stretches – which after 5 days of gritty Garden Route Giro racing will be all-to-welcome on the celebratory final stage.

Grit. Gravel. Glory.
