JASMIJN MULLER

Cycling (7)

Hi ! I am Jasmijn Muller, aka ‘Duracell Bunny on a bike‘. This nickname was given to me for my ability to just keep going; not a bad quality for an endurance cyclist. I am the owner of BE THE EGG Cycle Coaching and, if you give me the opportunity, the coach who will go the extra mile for you and help you take your cycling performance to the next level. 

I work with endurance and ultra endurance riders, be it to help you train for your first century ride, set a new timetrialling PB, take on an ultra race or record attempt or simply to get fitter, go faster or wander a little farther.
 
In the last few years I have built particular coaching expertise in long-distance cycling and women’s cycling.
 
Riders training with me benefit from the highest coaching qualifications, the latest endurance and cycling-specific sport physiology know-how, broad and personal international racing-winning experience, and insights from having coached 200+ riders for the biggest (ultra)endurance challenges. Riders training with me include National Champions, World Record Holders and ultra race winners, but I equally enjoy supporting those preparing for a hilly Sportive, their first Audax or multi-day event. 

JAS THE COACH

As a coach, I am passionate about inspiring and supporting others to realise their goals and optimise their athletic potential: To help other cyclists DREAM BIG, SET GOALS and TAKE ACTION to get FITTER, to go FASTER and explore FARTHER.
 
My background is in data analysis; my passion is for people and places, and what it takes to take people places, literally and metaphorically.
 
I have over 20 years’ experience as a trainer and consultant. As a trainer, I bring transferable skills and knowledge from years of teaching ballet and instructing scuba diving from beginners through to ‘Train the Trainer’ level. Ballet demands discipline and gives a a solid foundation in and understanding of good posture, core stability, flexibility and leg strength. While scuba diving is simply the most wonderful way to teach people breathing techniques, overcome fears and literally thrive ‘under pressure’. These experiences have also brought me strong multicultural awareness and permitted me to perfect my language skills – I coach in English, Dutch, German and French.
 
Importantly, I am highly adept at fine-tuning training to different needs, styles and schedules. For many years I have successfully juggled a full-time management consulting job with training for and competing in national and international cycle races, of increasingly longer distances. As a consultant, my focus has been on helping clients define and realise their vision through in-depth analysis, rigorous yet flexible planning and a pragmatic, results-driven approach. This approach is 100% transferable to my coaching approach.
 
My coaching approach is holistic: anima sana in corpore sano. I give my clients various tools for their toolbox. Training is about so much more than just pushing the pedals. My coaching encompasses structured training sessions both on and off the bike. As a Level 3 UKSCA Accredited Strength & Conditioning Trainer I can provide supplementary bespoke S&C training sessions for my riders, be it to prevent injuries, preserve muscle mass, build power or boost fatigue resistance. I also incorporate both mindfulness principles and practical mental skills exercises for my riders.
 
As a HRV4Training Mentor, I help all clients to pay equal attention to training and recovery. For my female clients, I also track trends in their menstrual cycle and associated symptoms via the HRV4Training Coach platform. I then use these individual patterns to adjust my female clients’ training to their hormonal fluctuations, be that pre-, peri-, or post-menopause, or during pregnancy based on the courses I completed with Dr. Stacy Sims, The Well HQ,  Absolute Physio and the Open University as well as ongoing monitoring of the latest female physiology research.
 

I am a firm believer that ‘knowledge is power’. I help prepare my riders for their key events by looking into the minute detail of race planning and strategy. I use a combination of TrainingPeaks, WKO5 and INSCYD for planning, tracking and analysing my riders’ training and progression.

I enjoy passing on knowledge to my riders and always keep a close eye on the latest academic publications, webinars and events in the field of exercise and nutrition. Alongside my full-time cycling coaching business, I am studying part-time for a MSc in Sport & Exercise Science, with a specialisation in Sport Physiology at Cardiff Metropolitan University.
 
My latest intitiative is a unique and comprehensive ultracycling training camp. Check out the Dotbooster website and a short article about it. The 4th annual edition of this unique training camp took place from 15 to 22 May 2026. Dates for Dotbooster No5 in 2027 will be released shortly.
 
In addition, I organise an annual training camp week and/or weekend(s) for my regular coaching clients, both in Wales where I live and in sunny places abroad.

COACHING SAMPLE

See map below for a sample of races and event I have coached riders for during the last few years. 

JAS THE ATHLETE

As an athlete, I like to ride far and fast, motivated by a thirst for adventure, a competitive spirit, but above all, a drive to expand my limits and learn more about myself and the world around me. 
 
I have competed in:

Other achievements include a Super Randonneur series during each of the last 5 years (200, 300, 400 and 600km brevets), London-Edinburgh-London (1400km, first female finisher in 2017) and Paris-Brest-Paris (1200km, 59 hours in 2019). 

In a moment of madness I also spent 70 hours on a turbo trainer, breaking the Zwift distance record (2017). The man I took the record from has since claimed it back by riding for 6 days straight in 2018. At the end of 2019 another male cyclist extended it to a whopping 10 days!  I don’t think I want to torture my neighbours for that long … 

In 2019, I was listed as one of Cycling UK’s 100 Women in Cycling for being one of the world’s foremost endurance cyclists and being an inspirational woman who encourages others to cycle. 

If I encourage others to ‘Be the egg’, face their fears and tackle their weaknesses, I should lead by example and pass on my learnings.
 
In 2022, I took on Europe’s longest unsupported ultra race, traversing 15 countries from the North Cape (Norway) to Tarifa (Spain), persevering despite issues resulting in 6 (!) pairs or shoes and 7 days off the bike due to injuring my hand during an unfortunate crash leaving me unable to use my brakes for a while and thus forced to a hiking/pool holiday …
 
The 7400km North Cape Tarifa in 2022 was a tough act to follow, but in 2023 the ‘short distance’ 1700km TransAtlanticWay not only exceeded my performance expectations – coming in 3rd overall and 1st woman despite a year of knee problems, but also thoroughly wetted my appetite for a longer ultra race again in future …
 
However, balancing racing desires against my health and being there for my coaching clients is important to me. So, you won’t see me race much throughout the year. And when I race, I always take care to do so with as little interruption and inconvenience to my clients as possible, whilst of course also passing on all those first-hand learnings from my races.
