The CHX Leadership

CHX Leadership

The CHX Leadership team blends deep expertise in business, science and individual & team coaching and development.  From technical programme design and scientific content to inspiring personalities for coaching and development, we think you will enjoy your contact with the CHX team from start to finish. And if enjoyment isn't enough, rest assured there is plenty to learn from the shared knowledge. 

What makes the CHX team unique is that we have worked and played together, for many many years.  We share values, expect the most out of ourselves, each other and our clients, and set out to try to enjoy every moment of life.

Alison Stork

Founder and CHX Challenge Director

Alison has worked as a registered Nutritional Therapist since 2007 and has worked for private clinics on Harley Street and in the City.  For the past 8 years Alison has predominantly been with Nuffield Health as a clinical nutritionist providing advice and support to individuals and the corporate market, working with businesses such as Allen & Overy and Cadbury’s.  

Alison is now CHX resident nutritionist, leading discussions on nutrition and performance and working 1-2-1 with clients where needed.  She works closely with our chef to ensure that the nutrition for each group is healthy, balanced, fresh and fun!  


Alison has a passion for sports and fitness, in particular hiking, and trail running.  She has competed in numerous events including coming 17th woman in the Chamonix Sky World running championships in 2011 and 35th in 2016, as well as 4th in her first 60km trail race in October 2016.  These hobbies have taken her to the Andes, the Himalaya and of course across the Alps.  When not on a mountain, you will find Alison in her kitchen - she is passionate in her belief that food and what we eat impacts on every aspect of health, wellbeing and performance.

Alison is currently studying a Masters Degree in Food Policy at London University and works voluntarily for the Trussell Trust (food banks).  She also manages CHX’s charitable fundraising efforts in the winter months.

Robbie Udberg

Head of CHX Challenge

Robbie joined CHX in 2018, having spent 9 years at Chelsea Football Club, where he most recently held roles as Head of Player Development and Performance Manager with the women's teams. Having studied under Chris Beedie, Robbie started with CHX delivering Performance workshops, focused on social and physical environments; he now blends running the operations of CHX Challenge events with exploration of how clients can unlock higher performance levels through modification of physical, social and altruistic environments.

Interested in the profound impact that environments have on people and their performance, Robbie is passionate about helping to develop others and in 2019 he will complete a Master's Degree in Environmental Psychology, further exploring this subject.

Robbie was brought up in the mountains and has a real passion for the outdoors. He personifies the CHX belief that bringing the outdoors into your life can help you achieve more and perform better.

Candy Stork

Head of Operations 

Candy runs the entire back office of the business, but would much rather be on the trails or leading on the entertainment! A young family means she can only join us on our events for a couple of weeks a year, but that does mean she will be the one you have contact with regarding all booking logistics which is good news! 

Her background is in HR, Accounts and Admin support but she has also spent 10 years working in the health and fitness industry and is a qualified fitness instructor who loves to teach a variety of classes, the most popular being Ski Fitness, Boxercise and Cagefit.

Candy was introduced to the mountains in Chamonix by Damien and Alison and found their enthusiasm to be highly infectious. Her first weekend was packed with exhilarating walks, stunning views and several cold beers. It’s fair to say that all aspects were fully embraced!

In 2016 Candy has been fundraising for Streets of London Streets (homelessness) and also works closely with Alison on the CHX Challenge business.

Nic Clarke

Technical Advisor and Challenge Lead

Nic has spent his entire adult life climbing, mountaineering, hiking, biking and generally having fun in the mountains.  You could argue strongly in fact that his is not a particularly adult life! He and Damien started climbing together in Chamonix Mont-Blanc in 2001, having worked together in health and fitness for the previous 4 years.

He is a highly qualified personal trainer, but more importantly for CHX, he is a hugely experienced mountain adventurer who was a key member of the Everest Max team in 2006.  This is the team that became the first to go from the lowest point on earth to the highest - cycling from the Dead Sea in Jordan through 8 countries and finishing by climbing to the summit of Everest! 

Nic also knows the alps like the back of his hand and lists trail running and hiking as his favourite activities, with indepth experience of all the CHX routes. At CHX, Nic advises all Challenge participants on preparation and kit. He then hosts and leads on our Challenge fundraising events. But please ignore his snack ideas, they are nutritionally disastrous!   

Damien Stork


Damien lives in Chamonix and London and spends his time either working on the programme content with the Science team, designing programmes for clients, holding workshops and seminars, or hosting CHX events in Chamonix.  

He has spent his entire life working in and participating in a variety of sports at the same time as developing a career in the Talent Management sector.  Between 1999 and 2013 Damien built businesses in resourcing and talent management consultancy, most recently as part of the very successful private equity-backed management team that set up and then sold Ochre House Talent Management (2006-2013), a global consultancy that won multiple awards for its leading-edge programmes for hiring and developing management and executive teams.


On a personal front, since 2001, Damien has combined corporate life with climbing and trekking all over the World, including the Andes, the Himalaya and SE Asia.  It is Chamonix he now calls home, and it is the challenge of the extraordinary environment that led him to the idea of CHX; the desire to introduce this place to businesses and individuals, combining the magic of the mountains with hard science, all aimed at personal and team development.

Damien works ½ day per week for The Connection – a large crisis centre in central London – helping clients prepare for and apply for work, coaching them to write CVs and get ready for interview.
