The 198 riders who start the 23-day event are phenomenal athletes. Many will complete the race but not until they peddle 2,200 miles across farm land, past historic monasteries, through charming villages, and up (and down) the Pyrenees and Alps. In my cyclist-rich area of central Texas, many conversations this month are colored with comments about “The Tour.”</p> <p>This year, as every year, some of the riders are involved in horrible crashes. Those who have to abandon the Tour often suffer broken collarbones or pelvises and concussions. The post-crash conversations by former cyclists and commentators often turn to safety. They ask: "Are the race organizers doing enough to protect the riders from these incidents?"</p> <p>Stage #1 of this year’s Tour was a rainy day and the roadway was slick. The day’s challenge was a “time trial” which involves a staggered start with each rider cycling as fast as possible over a 9-mile course. The Spanish veteran cyclist <a href="http://www.alejandrovalverde.es/en/">Alejandro Valverde</a> rounded a tight corner and his wheels slid across the pavement. <a href="http://www.express.co.uk/sport/othersport/823588/Tour-de-France-2017-Alejandro-Valverde-out-crash">Valverde crashed into</a> the metal barriers that lined the route. Among the 37 year old's injuries is a broken kneecap.</p> <p>Paraphrasing the TV commentators:</p> <blockquote><p>"Guys have been skidding out all day on that turn. It's dangerous."</p> <p>"When guys were doing their practice laps this morning they were slipping around that corner."</p></blockquote> <p>And this:</p> <blockquote><p>"As soon as they saw riders crashing out, why didn't the race organizers change out the metal barriers for hay bales? Bones get broken on those metal barriers."</p></blockquote> <p>In other words, after the hazard caused a problem, why didn't somebody in charge do something about it?</p> <p>Former U.S. cyclist Christian Vande Velde, now a TV commentator for NBC Sports had a particularly serious tone when he said:</p> <blockquote><p>The Tour organizers need to be “putting the riders first and foremost. This is the pinnacle of our sport. If it's not being done here, where <strong>is</strong> it being done? It's not being done.</p> <p>We need to look at the Tour de France for assurance that <strong>this</strong> is how it is done. <strong>This</strong> is the proper way to do everything.</p> <p>Why is a lesser race (than the Tour) going to make provisions that aren't being done at the Tour de France? They’re not.”</p></blockquote> <p>I also heard remarks that the organizers <a href="http://www.cyclingnews.com/news/chris-froome-disc-brake-debate-shows-riders-are-not-being-heard/">don't involve riders</a> enough in safety matters:</p> <blockquote><p>"Nobody wants to crash out. Riders need to be consulted about this stuff."</p></blockquote> <p>This sounds familiar and much like safety conversations in a workplace setting:</p> <blockquote><p>"People keep getting hurt with that machine. Why don't they fix it?"</p> <p>"That equipment is dangerous. It's a disaster waiting to happen."</p> <p>"Somebody's going to get killed with that thing."</p> <p>"We're left in the dark but it's our lives on the line."</p></blockquote> <p>And just like in workplaces, bike racing organizers <a href="http://www.uci.ch/mm/Document/News/News/18/21/26/2017_WT_Specifications-for-organisers_ENG_low_English.pdf">say the safety of the cyclists</a> is paramount importance.</p> <p>I call that "safety talk" but not necessarily safety action.</p> </div> <span><a title="View user profile." href="/author/cmonforton" lang="" about="/author/cmonforton" typeof="schema:Person" property="schema:name" datatype="">cmonforton</a></span> <span>Wed, 07/12/2017 - 10:46</span> <div class="field field--name-field-blog-tags field--type-entity-reference field--label-inline"> <div class="field--label">Tags</div> <div class="field--items"> <div class="field--item"><a href="/tag/safety" hreflang="en">safety</a></div> <div class="field--item"><a href="/tag/alejandro-valverde" hreflang="en">Alejandro Valverde</a></div> <div class="field--item"><a href="/tag/tour-de-france" hreflang="en">tour de france</a></div> <div class="field--item"><a href="/tag/safety" hreflang="en">safety</a></div> </div> </div> <section> <article data-comment-user-id="0" id="comment-1874360" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1500474461"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Very interesting, thank you. </p> <p>This seems to be a subset of the type of thinking we see in almost every workplace. (Prompted by my 16yo son's admission that he ignored the Safety portion of his Life &amp; Career class because "it was boring"...)</p> <p>I know there are cultural &amp; institutional barriers to thinking about safety, but it's almost like people deny cause and effect under some circumstances. Are these concepts too abstract for some otherwise smart people, or are we asking the wrong questions? Is simple boredom with the drab nature of the problem one of the barriers?</p> <p>In the racing world, cause and effect calculations might be extra boring because of their proximity to exciting sports people!
