Martijn Rasenberg and William Colorado Join Q36.5 Pro Cycling Team as Stagiaires
Q36.5 Pro Cycling are happy to announce the addition of two new stagiaires for the remainder of the season. Martijn Rasenberg (Netherlands) and William Colorado (Colombia) will get the chance to race in our beautiful Q36.5 kit in a variety of races. William and Martijn are two very different riders who will fit right into the varied program we have for August, September and October.

Martijn Rasenberg from Terheijden, Netherlands started riding his bike when he was just seven years young. The moment Martijn could start to race his granddad bought him a bike and he never stopped since.
This year the 23-year-old rider who represents Parkhotel Valkenburg made waves by winning the ‘Slag om Woensdrecht’ in the Netherlands. It was a solo win that prompted Jan Janssen (1968 Tour de France winner) to state: “I am impressed with how he races, and I hope he will turn profesionnal soon.”
“I am a rider who likes hard races,” Martijn admits. “I attack, make the races, try solos or can even win a sprint of a small group. The harder the race, the better.”
Rasenberg not only won Slag om Woensdrecht but also Omloop der Kempen, Ronde van de Achterhoek and the general classification of Flèche du Sud. His audacious attack at the national road championships in June almost gave him the red white and blue jersey
“I like winning for myself but I also love winning with the team. Q36.5 Pro Cycling Team is a team where you can really grow as a rider. I want to give the team my best. Having this place hopefully gives me the chance to show the same and make my biggest dream come true: to become a professional cyclist.”

The second stagiaire is William Colorado from Pereira in Colombia. The 21-year-old represents GW Erco Shimano and has represented Colombia on the international stage as well.
William said: “I feel really quite happy to be part of the Q36.5 Pro Cycling Team. I could say that this is the opportunity I have always wanted. I am extremely motivated and eager to do an excellent job and contribute as much as possible to achieve success as a team. As a rider I would say I am quite complete with good climbing skills and a good time trial.”

William was the runner-up this year in the Colombian U23 road race and has done well in many races on home soil. He also raced consistently in the Giro NextGen and Course de la Paix. In 2021 he won an important junior race in Italy called La Ciociarissima.
“My best memory was becoming national champion of Colombia and winning my first classic race in Italy. I started cycling thanks to my dad, who liked me to accompany him on his rides. That’s where my love for cycling was born. My biggest dream is to succeed in European cycling and make my family proud.”
Head of Racing Alex Sans Vega said on the two new arrivals:
“Incorporating stagiaires into the team is a great way to test new riders. The success of a rider is not only the list of results on statistics websites or FTP numbers. In race situations we can see how these two guys fit into a team. Do they do their job well? Do they follow instructions? How do they get along with fellow riders and staff? Those are also important parameters, and this trial period gives us that opportunity.
In Martijn and William we have two very different profiles. Martijn is a Dutch rider who does well in hard, flatter races under challenging weather. He will do a program where strength and aggressive racing is important. William is a climber type who will do well in the hillier races we have on the program this autumn.
I am looking forward to working with these two riders and see what we can achieve together.”
