7th stage ofthe Vuelta : Guillaume Martin wins the best climber jersey

With Ekoï AR15 helmet and Ekoï PersoEvo10 glasses

It wasn't necessarily expected today but there was a running movement on the 1st ascent of the day. So I was able to integrate the breakaway and take points in the mountain standings. I put in a lot of effort and tried to finish as well as possible. Of course the best climber's jersey, we will do everything to keep it! " During a completely unbridled stage rich in twists and turns, the Cofidis team shone once again Four riders from the team have made the breakaway. Guillaume Martin, 5th on the stage, puts on the best climber's jersey, a great reward for the whole team. Pierre-Luc Périchon and Victor Lafay were the first to join the breakaway after an hour of racing.When, José Herrada and Guillaume Martin, in a group of pursuers, ended up making the junction in the ascent of Puerto de Orduna. The riders had to climb this 1st category pass twice and Guillaume Martin was 2nd each time at the top of the pass. Result: the Normand pocketed precious points in the mountain classification, enough to take the lead. -Guillaume started the race with four other riders - Valverde, Woods, Peters and Fraile - all already stage winners on a Grand Tour. The Normand attacked several times before finishing in 5th place. For the third time in a row on this Vuelta, he finished in the ‘top 10’. On arrival, Guillaume Martin was able to don the polka dot best climber jersey, his first distinctive jersey on a Grand Tour. A great reward also for the incredible collective work provided by his team members. From now on, everyone will get down to 'defending' this jersey on the roads of the Vuelta. Guillaume Martin : "I had fun and I hurt myself too! On this Vuelta, we see some u...

TDF 2020/Stage 11 : Guillaume Martin still ranks 3rd in the General Classification

With the Ekoi Corsa Light & Glasses Ekoi Persoevo 10

The day after a minor crash, the leader of the Cofidis team (3rd overall) wanted to experience a quieter stage. And this is exactly the expected scenario that unfolded between Châtelaillon-Plage and Poitiers (167.5 km) where his teammates supported him seriously throughout the day. The vigilant team to the endThis long day between Châtelaillon-Plage and Poitiers (167.5 km) went off without a hitch for the leaders, Guillaume included. At the end of the stage, Nicolas Edet and the whole team were keen to place themselves at the forefront in order to support him until the end and avoid the traps. On arrival, Guillaume Martin, who praised the work of his teammates, said he was satisfied with this stage. On his hand, Elia Viviani did not manage to find the opening in the sprint and finally finished 17th . Guillaume Martin's hot reaction“I wanted to have a quiet day after the crash yesterday and I did. We were attentive all day and we stayed focused. In the end, Nicolas (Edet) and the whole team had a great work to keep us in the front and not waste too much energy. From start to finish, it was a good job. It allowed us to have a relatively calm day and to consider the rest with serenity. I felt better than after yesterday's stage. I still felt in my back and neck that it was quite sore at the start of the stage. It wasn't a super enjoyable day on the bike but it was. And I'm glad I got through the day without any problems. "

TDF 2020/ STAGE 10 : Elia Viviani ranks 4th

with helmet EKOI AR15 and Glasses Premium 80

Elia Viviani was able to join in the battle for the sprint where he pocketed 4th place and thus demonstrated his rise to power. Guillaume Martin, victim of a minor fall halfway through, benefited from the support of his teammates to preserve his 3rd place overall. After a well-deserved rest day, the peloton hit the road again on Tuesday. And for the first time in twenty years, a stage took place entirely in Charente-Maritime, to the delight of the public who came in large numbers throughout the 168.5 km covered on Tuesday. At Cofidis, we knew that it was a risky stage because of multiple factors including the wind from the ocean - ultimately relatively weak - but also the many roundabouts, islets and urban developments that made the more difficult race. Viviani confirms her return to business When entering Rochefort, Guillaume Martin was caught in a fall, apparently not serious. The rider also complained about his back at the finish. After the crash, he benefited from the invaluable support of his teammates to get back into the peloton. He then strived to stay in the wake of the best, thus protecting his 3rd place overall. The Norman nevertheless wants to be reassuring on his state of health and hopes "a day a little calmer", tomorrow, in order to recover well. His sprinting teammates got involved in the final battle. Elia Viviani, who is gradually regaining full possession of his means after having been touched in the foot in the first week, remained in the wake of the most fit riders of the moment. He finished in 4th place, his best result on this edition of the Tour de France. A clear rise in power and a ranking that he hopes to improve from tomorrow whe...



The leader of the Cofidis team hung on this Sunday during the final stage of the Pyrenees to keep his 3rd place overall. Guillaume Martin showed great courage and remarkable composure by conceding only 11 seconds on the winner of the day (Pogačar) and the new yellow jersey (Roglič). You had to have your heart set on Sunday following this 9th stage, the 2nd and last in the Pyrenees. In question ? The lack of visibility, the mercury - to less than 15 ° C - and especially the hellish pace of the race. Guillaume Martin, always in tune After the multiple attempts at breakaways and the solitary flight of Marc Hirschi, the Jumbo-Visma imposed their pace in the ascent of the Col de Marie-Blanque, undoubtedly one of the most difficult climbs of this start of Tour de France. Guillaume Martin, who had so far benefited from very good work from his teammates, held on as the field of leaders shrank. And then, 20 km from the finish line, the attacks started. Pogačar, Bernal, Pogačar again. Guillaume, he held on. A 3rd place in the dearly defended general If he was finally left behind by a handful of seconds, squad leader Cofidis showed quite a bit of composure as he participated in the counterattack. While Pogačar, Bernal, Roglič and Hirschi fought for the final victory, we saw in the distance the group of riders led by Guillaume. The Normand therefore resisted until the end and from an accounting standpoint, it is a success. He conceded only 11 seconds to the winner of the stage, Pogačar. In the general classification, the Frenchman remains 3rd, 28 seconds behind the new yellow jersey, Primož Roglič. Martin is the only rider to have seen his position in the “top 10...



He hung on, attacked and gave it his all. Guillaume Martin defended with panache his 3rd place in the general classification in the Pyrenees, while constantly remaining in contact with the big favorites for the final victory. Take a look back at a day when the Normand once again showed the full extent of his talent.  There had been the arrival at Orcières-Moriette and this attack in the last kilometer. For Guillaume Martin, there will now be the 1st stage of the Pyrenees, where he dearly defended his 3rd place overall. Leader Cofidis, supported by Pierre-Luc Périchon and Nicolas Edet until he climbed the Port of Balès, then kept up with the hellish pace imposed by the Jumbo-Visma, then resisted multiple attacks.  Collective work and a breathtaking finale   In the last hectometers of the Col de Peyresourde, less than 7 km from the finish, the Norman went on the attack. With panache and self-sacrifice, he forced the favorites to respond. Then, in the last kilometer, another attack, new proof of courage. Until the end, Guillaume Martin dearly defended his coveted 3rd place overall.  He is 9 seconds behind the yellow jersey, Adam Yates, and is one of only 4 riders in the ‘top 10’ to have retained his place in the overall standings on this eventful day. Guillaume Martin knows, however, that nothing can be taken for granted. The battle begins again tomorrow. Between Pau and Laruns, the road will continue to climb, the passes will follow one another (five on the program) but the determination will always be as strong and intact. GUILLAUME MARTIN'S HOT REACTION  "The second part of the race was very intense from the Port of Balès. Pierre-Luc (Périchon) and N...

TDF 2020 / Stage : 7 Christophe Laporte ends 4th /Guillame Martin is 3rd in the general classification

with helmets EKOI AR15

This Friday, at the end of a particularly hectic stage, Christophe Laporte took 4th place in the sprint and Guillaume Martin climbs back to 3rd placein general  classification. Now, it's time for two days that promise to be breathless & explosive in the Pyrenees. It was to be a transitional stage before the Pyrenees. However, the day was particularly delicate with the edging initiated by the Bora-Hansgrohe then the Ineos-Grenadier. At Cofidis, Guillaume Martin, well supported by his teammates, managed to stay constantly in the 1st group. He also passed a few important stints at the end of the stage before positioning himself well in the final. The Normand was rewarded for his efforts : he gained a place in the general classification and is now in 3rd place. For his part, Christophe Laporte, one of the few sprinters to have managed to stay in the leading group, will seek a nice 4th place in the final packaging. This is his 2nd best performance after his 2nd place in Pau in the Tour de France 2018. Change of scenery this weekend with two stages in the Pyrenees which promise a beautiful spectacle. On the program : 8 passes to climb, including four of the first category and one out of category. Thus, you will have to climb the Col de Menté, the port of Balès and the Col de Peyresoude on Saturday, then the Col de la Hourcère, the Col d'Ichère and the Col de Marie Blanque on Sunday.   Christophe LAPORTE (4th on the stage): “We have been working hard all day. There was a quick break and then Bora-Hansgrohe accelerated. We were in front with Guillaume (Martin) and Pierre-Luc (Périchon) then it broke again when crossing Castres.  I felt good and I'm a little dis...

TDF 2020 / Étape 6 : Jésus Herrada finishes 2nd on the stage

With Ekoï helmet

At the end of stage 6 of the Tour de France, leading to Mont Aigoual, Jesus Herrada of the Cofidis team is the only rider to have kept pace with the winner of the day, Alexey Lutsenko (Astana team): he finished second in the stage 55 seconds behind the Kazakh. When the winner of the day, Alexey Lutsenko, left alone in front, Jesus is the only one to respond. This great effort shows all the qualities of Jesus, he who won in a stage in the Vuelta last year. At 30, the climber signed his best result on the Grande Boucle when he participated for the 6th time in his career. Guillaume Martin, who was able to count on the support of his teammates as he does every day, finished the stage in the peloton of the favorites (27th). He thus retains his fourth place in the general classification, 9 seconds behind the yellow jersey, Adam Yates. Jesus HERRADA (2nd on the stage): “I'm happy with my performance but inevitably a little disappointed not to have been able to fight for the final victory. There were some very good riders in the breakaway. It was hard to keep up with the pace but I'm happy that I managed to stay in a good position & finish in 2nd position. There, I am very tired! I will focus on recovering well to be in good shape in the Pyrenees. " Guillaume MARTIN (4th on general classification): “We continue our excellent start to the Tour de France. We wished we had a rider in the break and Jesus assured. He was not far from victory and his 2nd place was a very good performance. Behind, we remained well grouped and well placed in the decisive moments. In the end, I just followed the group of favorites. It was another good day for the team and for me!"

TDF 2020 / Stage 5 : Guillaume Martin is 4th on the general Classification

With Ekoï Helmet

Two days after arriving in Orcières-Merlette, a longer & more vigorous final climb awaits the riders tomorrow at Mont Aigoual. Enough to further refine the positions in the general classification and allow Guillaume Martin to shine again. You have to know how to preserve yourself when the effort is long and lasts 21 days. This is the challenge offered by the Tour de France & the peloton is well aware of it. This Wednesday between Gap and Privas, it was therefore decided to ease off slightly while high mountain was on the program yesterday and will continue to be tomorrow. Guillaume Martin was able to preserve himself At Cofidis, we also wanted to recover well when the whole team was hard at work the day before in order to help Guillaume Martin to climb to 3rd place on the stage. Even today, all took turns supporting their leader. In the last kilometers, Guillaume was keen to get back to the top positions in order to protect himself and cross the line safely. Following the penalty suffered by Julian Alaphilippe, the Normand is now 4th in the general classification and 1st French. The stage ended with a sprint as announced. In the last kilometers, Elia Viviani, weakened by a burcitis in the right foot since the start of the Tour, preferred to get up. The Italian sprinter of the Cofidis squad continues to hang in there and hopes to quickly regain his abilities. Christophe Laporte therefore represented the Cofidis team in the sprint and finished in an honorable 12th place. Mont Aigoual, full bodied finish So tomorrow the road will rise again with the 2nd summit finish in three days. This time around, the peloton will have to climb Mont Aigoual, which has only ...
