  • CYCLING LEGENDS Autoworld in Het Thema Van De Tour De France!
    Persbericht Van 20 juni tot 25 augustus 2019 Autoworld - Brussel Stelt voor CYCLING LEGENDS Autoworld in het thema van de Tour de France! Deze zomer maken we een bijzonder moment mee: de Ronde van Frankrijk vertrekt dit jaar in Brussel! Om dit te vieren, organiseert Autoworld naast de expo over het honderdjarige bestaan van het merk Citroën, een unieke terugblik, waar u alles komt te weten over de geschiedenis van het wielrennen en zijn legenden, van het prille begin in 1819 tot nu. Wist je trouwens dat de hal van het jubelpark, waarin Autoworld nu gehuisvest is, in 1902 het toneel was voor het Auto – en fietssalon? Een ongewone tentoonstelling Omdat de Ronde van Frankrijk dit jaar in Brussel vertrekt, denken we ook terug aan de eerste zege van de grootste wielerkampioen aller tijden: Eddy Merckx. Wist u trouwens dat de gele trui dit jaar ook 100 jaar bestaat? Wat alles extra magisch maakt, is het feit dat Eddy Merckx het record draagt voor de meeste dagen in het geel tijdens de Ronde van Frankrijk. Hij heeft de felbegeerde kleur maar liefst 96 dagen lang gedragen. Dit legendarische stukje wielergeschiedenis komt tot leven in de tentoonstelling 'Cycling Legends', die verdeeld is in drie hoofdthema's: * 200 jaar verhalen over de grootste kampioenen (1819 – 2019), * de galerie over het honderdjarige bestaan van de gele trui (1919 – 2019) * een deel dat exclusief gewijd is aan de grootste Belgische kampioenen (1919 – 2019). Bereid u alvast voor op een golf van emoties wanneer u de fietsen, uitrusting en trofeeën van tal van kampioenen met eigen ogen ziet, naast een collectie zeldzame oude posters, historische documenten en andere interessante stukken.

  • Worshipped, Abused, Rejected
    I NTRODUCTION Worshipped, Abused, Rejected HE LIVED THE FRENETIC LIFE of a celebrated sports icon. He died the solitary death of a drug-dependent depressive. Marco Pantani’s ending faithfully reflected his star-crossed life and times. The quirky, pugnacious Italian climber was frequently alone at the end of punishing mountain stages in cycling’s greatest races, minutes ahead of the opposition. And he was alone again, tragically so, when he died in the fifth- story room of a hotel called Le Rose in the afternoon of a somber St. Valentine’s Day in February 2004. Outside his window, life still bustled in the streets of Rimini, while waves continued to foam onto the beach of this Adriatic resort. Pantani was 34. On February 18, some 20,000 people came to Pantani’s hometown of Cesenatico, fewer than 20 kilometers north of Rimini. They watched and applauded his final 2-kilometer journey: from his funeral at the church of San Giacomo, where he was baptized, then alongside the Leonardo da Vinci–designed port canal, to his burial at the small coastal town’s cemetery. His grave has become a shrine, like that of Italy’s other tragic cycling champion who died before his time, Fausto Coppi, who was just 40 and still an active racer when he was claimed by malaria that had been misdiagnosed as the flu.

(EJiiPfflNITHIS Lance Armstrong Has Something to Get Off His Chest He doesn't use performance-enhancing drugs, he insists, no matter what his critics in the European press and elsewhere say. And yet the accusations keep coming. How much scrutiny can the two-time Tour de France winner stand? by Michael Hall In May of last year, Lance Armstrong was riding in the Pyrenees, preparing for the upcoming Tour de France. He had just completed the seven-and-a-half-mile ride up Hautacam, a treacherous mountain that rises 4,978 feet above the French countryside. It was 36 degrees and raining, and his team's director, Johan Bruyneel, was waiting with a jacket and a ride back to the training camp. But Lance wasn't ready to go. "It was one of those moments in my life I'll never forget," he told me. "Just the two of us. I said, 'You know what, I don't think I got it. I don't understand it.1 Johan said, 'What do you mean? Of course you got it. Let's go.' I said, 'No, I'm gonna ride all the way down, and I'm gonna do it again.' He was speechless. And I did it again." Lance got it; he understood Hautacam—in a way that would soon become very clear.

  • Terugblik Op De Carriere Van Ex-Profwielrenner Matthijs De Koning
    Terugblik op de carrière van ex-profwielrenner Matthijs de Koning. De finish van de Tour de France is op zondag 29 juli geweest. Veel renners hebben om allerlei redenen de finish niet bereikt. Het uitrijden van de belangrijkste wielerwedstijd van het jaar is op zich al een prestatie van formaat. Matthijs de Koning, Scherpenzeler en voormalig beroepswielrenner, heeft dit in het verleden ook eens gepresteerd. Oud Scherpenzeel blikt terug op de carrière van deze Scherpenzeelse ex-topsporter. Matthijs de Koning wordt op 18 maart 1949 geboren op de Willaerlaan in Scherpenzeel. Hij is de jongste uit een gezin van vier kinderen. Matthijs heeft één broer en twee zusters. Zijn vader werkt bij bandweverij “De Driekleur”. Als Matthijs zes jaar is, verhuist het gezin naar de Plataanlaan, waar Matthijs zeventien jaar woont. Op jonge leeftijd gaat Matthijs, die in die tijd Matti wordt genoemd, voetballen bij voetbalvereniging Scherpenzeel. Met leeftijdsgenoten worden na schooltijd en in de vakanties wielerwedstrijdjes gehouden. Met hen gaat Matthijs ook bij de Tour de Junior in Achterveld kijken. Geïnspireerd door de prestaties van andere Scherpenzelers bij dit wielerevenement doet hij in 1964 voor de eerste keer op een gewone fiets mee aan deze wielerwedstrijd. Om het volgende jaar op een echte racefiets te kunnen meedoen, gaat Matthijs een paar uur in de week als kegelopzetter in Hotel Café “De Zwaan” aan het werk. Voor 95 gulden koopt hij zijn eerste tweedehands racefiets. Hiermee wint hij in 1965 de Tour de Junior in de leeftijdscategorie van 16-jarigen. Zijn ouders gaan ervan uit dat hiermee een einde is gekomen aan de wielerloopbaan van Matthijs, omdat hij het volgende jaar vanwege zijn leeftijd niet meer in de Tour de Junior mag starten.

  • Alps Favor US, Says Movistar's Quintana
    SPORTS SATURDAY, JULY 25, 2015 Quintana bidding to eclipse ‘Lucho’ Herrera SAINT-JEAN-DE-MAURIENNE: Nairo Quintana will be aiming to cement the special relationship between Colombia and Alp d’Huez when tackling the mystical Tour de France climb today. The 25- year-old 2014 Giro d’Italia champion may be the most famous Colombian cyclist and Alp d’Huez the most iconic mountain in the sport, but it was Luis ‘Lucho’ Herrera who paved the way for riders in the Andean country 31 years ago. It was Monday, July 17 in 1984 on the 151km 17th stage of the Tour de France from Grenoble to Alpe d’Huez when the 23- year-old Colombian climber announced his talent to the world. The day started badly for Herrera, who was ini- tially distanced by the peloton as French pair Laurent Fignon and Bernard Hinault, the two favorites, battled for supremacy. But Herrera man- aged to cling on and by the foot of Alpe d’Huez he was alongside Fignon. Herrera attacked and reeled in Hinault before going on to win the stage at the Alpine colossus’ summit, joining the likes of cycling legends Fausto Coppi and Joop Zoetemelk as win- ners on Alpe d’Huez. Herrera, officially still an ama- teur, went on to finish the race 27th overall as Fignon won his second Tour-a year later Hinault would take revenge but France has not had a Tour winner since. The Colombian star would enjoy many more great days in cycling, winning the 1987 Vuelta a Espana and that same year earning his best finish in the Tour-fifth.

  • If You're Lucky Enough to Be Irish, You're Lucky Enough! St
    ICA Theme Profile If You're Lucky Enough to be Irish, You're Lucky Enough! St. Patrick’s Day Celebration Created by: Richard Mullins Working intensity: moderate to very hard Length: 50 minutes Concept Behind the Profile Ireland has a population of 5 million people, but 70 million people call it home. We are the friendly Irish and we are the fighting Irish! I’ve picked several key moments in Irish culture that got Ireland noticed across the world and tied them into working intervals of varying duration. The terrain of Ireland is constantly changing, so be prepared for terrain that could always shift under your feet! The scope of this profile is to work below threshold, then at threshold, and finally give riders the option to work above threshold. When you ask a tourist about Ireland or if you think about how Ireland is perceived outside of our small isle, we are, in many cases, associated with the colour green, Guinness, and anything else that fits a stereotype. All one has to do is look at any tourist T-shirt! Let’s think beyond these stereotypes; Ireland has thrown herself into the world arena many times over the last few years (and before that) in the areas of dance, film, music, economics, and politics. These pivotal moments have slowly changed how we are perceived in the world. As the ride begins, I do like to mention a few quotes that various film and TV characters around the world have referenced about Ireland to lighten the mood. I will include some at the very end of this profile.

In a different mood Armstrong dubbed the Tour as "the most gallant athletic endeavor in the world." He may well have been right on both occasions. The Tour de France was created by Henri Desgrange who was looking for a way to promote his cycling newspaper, L'Auto. In the first year it was a simple six-stage loop of 2,428 kilometers around France. Riders worked alone with no crew or assistants to help them along the way. In 1906, to add to the challenge, a stage was added into the Pyrenees.
