I’ve ridden the route so many times just by accident, before it was even announced as the women’s road race,” she tells the Guardian. "Every time I wheeled my bike out of my parents’ garage I turned right and I was on the worlds circuit.”

Jumbo-Visma gave Primoz Roglic and Steven Kruijswijk's power meter data (major climbs) to AD. The watts that brought third place at Giro d'Italia (Roglic), third place at Tour de France (Kruijswijk) and first place at Vuelta a España (Roglic). https://t.co/rkJxlMUBr4pic.twitter.com/SSQCtIZ4sw

Jumbo-Visma has just released power data from two of their Grand Tour leaders, Primoz Roglic and Steven Kruijswijk.

The data shows some pretty big w/kg numbers, but there's nothing here that looks 'extraterrestrial' to us. Diving into the data for Roglic from the Giro suggests that he was never really there on the climbs, relying more on his TT pedigree to secure a 3rd place finish behind Richard Carapaz and Vincenzo Nibali. The loss of 1kg in body weight also shows the toll that Roglic's mid-race illness had on him. 

Kruijswijk's Tour de France data is a good indication of how conservative the riders have to be with the efforts on longer climbs. The comparatively short Planche de Belles Filles was completed in 20m37s by Kruijswijk at a power of 388w (6.16w/kg). Compare that to 350w (5.5w/kg) over the mammoth 51m21s climb up the Tourmalet and you can see why having strong teammates to help pace and take the wind for as long as possible is crucial. The day after the Tourmalet stage, Kruijswijk again hit over 6w/kg on the sorter climb. 

Roglic's Vuelta data shows the consistency needed to win a three-week race. The steep climb of Los Machucos saw Roglic push a huge 408w (6.3w/kg) for 22m48s. He repeated this performance two days later on the 29m34s climb to Santuario del Acebo, pushing 406w. For us, this was his most impressive performance as the numerous gradient changes would have suited GC rival Valverde more. Will we be troubling the front-end of a Grand Tour? That'll be a no.

The Telegraph’s got a nice interview with Eileen Cropper, who competed in the first world championships women's race in 1958 (a mere 65 years after the inaugural men's event).

She opens by suggesting the reporter is, “only about 60 years late,” and carries on in a similar vein.

She says a number of local shops offered her a bike when they heard she was riding the world championships.

“I got three bikes out of it. I had to say to each one that I had ridden their bike in the race … but I didn’t.”

She says the race itself was “an absolute shambles” and describes rivals popping pills while they were riding.

It’s well worth a read.

The LCC will support the youth climate strike movement by riding from St John's Church Park to Parliament Square, meeting at 10,30am for an 11am start. LCC say: "The climate crisis is the biggest threat facing humanity, and cycling has an important part to play in bringing about solutions. With 20% of London’s carbon emissions coming from road transport, a massive reduction in motor traffic and a rapid expansion of the network of high-quality cycling infrastructure is urgently needed.

"Fortunately, this is an entirely achievable goal. We have a roadmap for decarbonising London’s road transport, and now we just need the Mayor and Borough Council Leaders to deliver it. Doing so will create a better city for everyone - one with fewer cars, less pollution, greener streets and much, much more high-quality cycling infrastructure – while helping cut carbon emissions, helping to protect the future of the planet and millions of people."
