“52mph in a 20 zone… Lycra lout cyclists are creating death traps all over Britain.”

That is the news sat proudly atop The Telegraph newspaper’s front page this morning, the promo for an in-depth analysis of Strava segments across London and the respective speeds reached to achieve their fastest times. However, as many people have since pointed out online, the speeds cited in lots of the paper’s examples appear not to be the feat of unsuspecting cycle commuters who should really be ditching the suit and tie for a summer challenging Mark Cavendish at the Tour de France, but rather just the result of dodgy GPS data.

The feature centres around a segment on Chelsea Embankment, Tite St to Chelsea Bridge, where the Telegraph claims a cyclist (who probably “felt that was a commute well spent”) had covered the 630-metre segment at 52mph (84km/h), evidence “cyclists are turning UK roads into death traps”. 

What the feature does not appear to question or fact check is why a London cyclist on their way to work would be faster even than what six-time Olympic champion Sir Chris Hoy says was his fastest ever speed, 80km/h achieved on an optimal indoor velodrome in the keirin, a track cycling event where riders slipstream behind a derny to achieve faster speeds.

On another cited segment the newspaper alleges a cyclist smashed past Lambeth Bridge at 46mph (73km/h), hitting a max speed of 52mph, despite the average speed for their ride being 16mph (25km/h). A third claims a rider, whose power meter (a calibrated device giving an accurate measure of how much power a rider is putting through the pedals) reports he averaged 204w, but had taken the fastest time at a speed of 42mph (67km/h).

According to Bike Calculator, an 80kg cyclist riding a bike weighing eight kilogrammes (on a perfect summer’s day with no wind) would have to hold 2,500w to ride the earlier Tite St to Chelsea Bridge segment at 52mph.

As one cyclist on social media responded to the article, “If you can ride through London at 52mph, please contact your local professional bicycling team. They may be interested in your skills.”

Others pointed out the “GPS glitches” apparent in the segments used, Chas Pope telling the newspaper: “You might want to check your research on the cycling article you’ve splashed on your front page. Virtually all of the fast times on the Strava
segments you chose have GPS glitches”.

Political reporter at The Guardian, Peter Walker, called the story “my absolute favourite anti-cycling news story of all time”.

“But congrats, I suppose, to the Telegraph for opening a new (if entirely fictitious) front against cyclists: being able to travel at 52mph on the flat,” he wrote on social media.

The story raises concerns about cyclists racing Strava segments putting pedestrians and other road users in danger, the story coming days after the ride-sharing app reminded the public that it already has a feature to flag segments as “hazardous”, removing the leaderboard.

Strava was commenting to road.cc in light of calls from the Royal Parks to remove a segment in Regent’s Park following the death of a pedestrian in a collision with a cyclist back in 2022. The rider involved will not face prosecution as the Metropolitan Police deemed there was “insufficient evidence for a real prospect of conviction”.

The case, thrust into the spotlight since a recent coroner’s inquest, reignited the discussion about cycling, the government now moving forward with introducing tougher legislation to prosecute cyclists who kill or injure through dangerous or careless cycling.

Commenting on the discussion around segments, Strava told us: “We are aware of the tragic cycling incident which occurred in London’s Regent’s Park in June 2022 and our condolences go to the victim’s family.

“At Strava, safety of our active community and those around them is a priority, and we have community standards that note that ‘sports happen in dynamic environments that we share with motorists, pedestrians, other people, equestrians, pets and wildlife’. Strava expects those in our community to ‘prioritise everyone’s safety and enjoyment of our shared resources and respect the law’. The behaviours related to this incident violate Strava’s ‘community standards’.

“At the end of last week, we received a request from Royal Parks to discuss the cycling route segment where the incident occurred. The ability to flag a cycling route segment as hazardous already exists in Strava. Anyone can report a segment that they would deem as hazardous. If segments are flagged as hazardous, achievements are not awarded for that segment and leaderboards are disabled. Any Strava community member who cycles on that same route segment will receive a warning of the hazards on that segment.”
