With at least 21 Tour de France riders now out of the race following a growing list of crashes - some the result of a fan taking a selfie at stage 15 - cycling advocate and injury specialist Mark Hambleton shares overlooked signs of concussion that road bike racers and everyday riders need to be aware of, and the impact of helmet-wearing on making an injury claim.
- Daniel Martinez was allowed to continue a stage earlier in the Tour after showing signs of concussion.
- In an earlier Tour de France, Romain Bardet crashed and continued racing for 90km before being diagnosed with a bleed on the brain.
- British Cycling published its first concussion guidance earlier this year, and this is the first year where the organisation has formalised rules giving it the right to withdraw riders from events if they are a safety risk.
- Helmet wearing only became mandatory at all stages of the Tour de France in 2005.
Hambleton is a partner at road injury law firm RWK Goodman, and specialises in representing cyclists as well as other vulnerable road users.
“There does not have to be a loss of consciousness suffered [in a road accident] for there to be a brain injury. In fact, only 10% of reported mild brain injuries involve a loss of consciousness.” Hambleton says. He has further commented on the subject.
“Symptoms of a mild traumatic brain injury include headaches, confusion, dizziness and memory problems, whereas more severe injuries lead to loss of consciousness and difficulty with speech and movement.”
Charlotte Webb, Senior Associate at RWK Goodman, adds “Mental fatigue is a very common symptom after brain injury. It is common to find simple tasks tiring to complete because greater concentration is needed. Many people report personality changes, feeling like a ‘new person’ after their injury. Someone with a brain injury [such as a concussion] may appear to be rude or insensitive, but it is the brain injury that has stopped them having the filter that the rest of us have.”
Hambleton notes that while cycling event organizers often mandate helmet-wearing to ensure their insurance cover is not compromised, cyclists who don’t wear helmets at other times may lose up to one-quarter of their compensation if they are injured in an accident. While most of us don’t need to worry about selfie-taking fans knocking us off our bicycles, Judges have previously found that cyclists who choose not to wear helmets are partially at ‘fault’ for the extent of any injuries following a crash.
“There are various lobbies for and against wearing helmets and at present, cyclists are free to choose because the benefits of wearing a helmet have not been proven. However, they need to be aware that the judiciary believes cyclists should wear helmets so those who decide not to are taking a chance with their damages if they are injured.” Hambleton says.

A founding contributor to CyclingUpToDate since its launch in January 2022, Ruben Silva has played a central role in shaping the site’s editorial direction and long-term growth. Before joining the project, he built his experience through independent blogging at Echelons Hub and by producing race previews for Ciclismo Internacional, developing a strong analytical voice rooted in daily engagement with professional cycling.
Beyond editorial work, he has been closely involved in the expansion and coordination of CyclingUpToDate’s wider network, helping establish and support sister platforms across multiple languages. This includes ongoing collaboration with CiclismoAlDia (Spanish), CiclismoAtual (Portuguese), WielrennenUpToDate (Dutch), and RadsportAktuell (German), contributing to a shared editorial vision and consistent international coverage.
He also helps oversee editorial governance across the network, setting standards for accuracy and consistency and coordinating updates or corrections when needed.
Originally from the Porto metropolitan area in Portugal, he holds a bachelor’s degree in Geography. His path into cycling journalism was shaped not through formal media training, but through independent reporting, community engagement, and sustained on-the-ground involvement in the sport.
Over the course of his career, he has conducted approximately 100 interviews across road cycling and cyclocross, ranging from one-to-one conversations and online formats to press conferences and on-site pre- and post-race coverage. His interviews include leading riders, team managers, and prominent figures within cycling media: Tadej Pogacar, Jonas Vingegaard, Mathieu van der Poel, Primoz Roglic, Wout van Aert, Joao Almeida and Tom Pidcock; managers like Patrick Lefevere and Joxean Matxin; and YouTube personality Bryan Kennedy (BKXC)...
Within 18 months of launch, he helped grow CyclingUpToDate’s English-language platform into one of the most-read cycling news websites, built entirely from the ground up. As both a professional journalist and lifelong cycling enthusiast, his focus remains on delivering accurate, timely, and well-contextualized coverage.

- It's going to happen at some point. It will happen to Tadej as well, we all get older. Jonas was in pretty great form at the tour. I still consider him a top two or three cyclist in the world, until he's not.awp15-11-2026

- Pogi takes care of his teammates in races and training. Tadej Pogačar is widely praised within the cycling peloton for his fair and egalitarian leadership, actively supporting his UAE teammates both on the road during races and behind the scenes at training camps. Rather than acting like an untouchable superstar, he has intense team loyalty by sharing daily chores, giving up personal glory to help domestiques, and publicly praising their sacrifices. Unlike some Grand Tour contenders, like Vingegaard, who occasionally train away from their squads, Pogi consistently attends team training camps alongside his domestiques, making the exact same sacrifices to build friendship. I love how Pogačar shares his teammates-domestiques, either when they succeed or win in races or when they simply just do a good job for him. It has to be a great moral boost for them. And then they work even harder and go even deeper for Pogi. This is teamwork.PogiSloFans15-11-2026
