The Tour Down Under’s emblematic climb, Willunga Hill, will not feature at this year’s race after it was removed from Saturday’s fifth stage due to an extreme fire danger warning and forecast maximum temperatures of 43°C in the area – sparking renewed calls for the race to ditch its title sponsor, oil and gas giant Santos.

Willunga Hill, an often-decisive staple of the season-opening WorldTour race in South Australia, was set to be tackled by the peloton three times during Saturday’s 176km route, the penultimate stage of the six-day event.

However, with predicted maximum temperatures of 43 degrees and an “extreme” fire danger rating for the Mount Lofty Ranges in place, the Tour Down Under organisers announced on Friday that Willunga Hill would be removed from the race entirely and the stage shortened to 131km.

That decision, made in consultation with local emergency services, South Australia Police, the riders, and the UCI, means that the stage will start in Brighton at 10.10am, an hour earlier than previously planned, and finish in Willunga township, which hosted the conclusion of stage one of last week’s women’s Tour Down Under.

The organisers also called on spectators to “avoid riding up Willunga Hill, be sun-smart, seek shade, and remain hydrated, and most importantly, follow messages from emergency services authorities throughout the day”.

The modifications to Saturday’s stage will almost certainly ensure that it will end in a bunch sprint and have little impact on the general classification, which is currently being led by Jay Vine. The Australian, who won the race in 2023, attacked on the Corkscrew alongside UAE Team Emirates teammate, and defending champion, Jhonatan Narváez, building up an advantage of over a minute on the rest of the field.

Sunday’s final stage of the race, which features a series of laps around Stirling, is expected to go ahead as planned.

“While the removal of the famous Willunga Hill climb is disappointing news for cycling fans – ultimately rider and spectator safety is always the number one priority for our event,” race director Stuart O’Grady said in a statement.

“Following consultation with emergency services authorities, riders and the UCI, we have agreed to proceed with a modified programme for Saturday’s racing.”

While hot conditions are expected at the Tour Down Under, which takes place at the height of the Australian summer, this year’s race has coincided with the country’s most severe heatwave since 2019-20’s “black summer”.

That year’s searing temperatures led to thousands of bushfires, burning up to 19 million hectares and resulting in scenes of devastation, some of which the Tour Down Under peloton passed through during the 2020 edition.

Ahead of Friday’s stage between Henley Beach and Nairne, won in a sprint by the Ineos Grenadiers’ new Australian signing Sam Welsford, the Tour Down Under organisers urged spectators to “remain hydrated”, and to help reduce the risk of fires by avoiding driving or parking in long, dry grass or on road verges.

“Hot cars in dry grass can cause a fire, which has a high chance of getting out of control in this weekend’s predicted hot and windy weather. If parking is necessary, it should only be done in cleared areas such as paved or gravel roads where the grass is not dry or long,” the race said.

The organisers also reminded fans that the race is non-smoking and that “outdoor barbecues should not be used along the TDU route”.

According to new analysis published this week by the World Weather Attribution, the effects of greenhouse gas emissions and human-caused global heating have made the heatwaves affecting Australia in January five times more likely.

Earlier this month, one person died and 300 properties were destroyed in bushfires that tore across south-east Australia.

It’s perhaps no surprise, then, that the news of Willunga Hill’s climate-related excision has sparked renewed calls for the Tour Down Under to cut its ties with Santos, the race’s long-term title sponsor – and one of Australia’s worst greenhouse gas emitting companies.

Last year, the company received approval for its Barossa gas project, widely regarded as one of the most emissions-intensive gas developments in the country.

Responding to the race’s Instagram post announcing the changes to Saturday’s stage, which included a reference to Santos, Steph wrote: “I love the TDU and I value the generous financial input of sponsors to help make the event possible… but honestly… the irony of tagging Santos in this post. Hope everyone can stay safe in such extreme conditions.”

Meanwhile, on Facebook, Sarah said: “Extreme weather events. Santos. The irony.”

The gas and oil producer’s status as the Tour Down Under’s naming rights sponsor – a position it’s held since 2010 – has long been viewed as one of cycling’s most egregious forms of ‘greenwashing’, making it a frequent target of environmental protests over the years.

In 2023, two women in their 60s were arrested after gluing themselves to a pile of bikes on an Adelaide street before the race started, while a few days later, another group of three partly naked women, again in their 60s and 70s, were also arrested ahead of the opening stage of the women’s race for allegedly exposing themselves.

“We are baring our ageing breasts and our wobbly bums in the hope of shocking,” one protester said. “Polite pleas and submissions have not been enough.”

And in the build-up to this year’s event, a number of high-profile Australian cyclists, including former national champion Brodie Chapman, joined the campaign to ditch Santos from the cycling world.

“It’s certainly time that the Tour Down Under looks for a new sponsor to more align with the values of the modern world, the Australian people, the natural world, and athletes,” the UAE Team ADQ rider said.

Another former national champion, Cyrus Monk, also said it was “embarrassing” that Santos continues to sponsor the country’s biggest bike race.

“I’d love to see another sponsor to be able to step in,” he says. “Obviously, the dream would be similar to the [Belgian] Renewi Tour, where the sponsor is a renewable energy company that is doing something better for the environment.”
