During her junior and Young Rider career, Millie represented her country at eight European Championships, claiming eleven medals. But the transition into her senior years was not without challenges. Following several serious falls, she developed post-concussion syndrome – a setback that tested both her resilience and determination.

The experience taught her to stay positive through uncertain times and strengthened her mindset as an athlete. In 2022, ready for a new chapter, she moved to Belgium to pursue her senior career at Karel Cox Horses, an international trading stable with top-level horses and a renowned breeding facility.

Since then, she has won several 5* classes and represented Great Britain in the Nations Cup. With her sights set firmly on the future, Millie Allen is a name to watch.

How did you first get into horses?

– My parents have a riding school and competition centre. My older sister rides, and we grew up spending time with the ponies. From a young age, horses have always been a natural part of my life. 

What would you say is your biggest strength as a show jumper? 

– I would say that my biggest strengths are that I’m dedicated and competitive. I believe these two strengths have been crucial for my development in this sport. 

What has been the most challenging – and the most rewarding – part of moving to Belgium to work at Karel Kox Stables? In what ways have you developed the most?

– It’s challenging to move further away from friends and family, but rewarding to gain experience and to achieve the goals I’ve set for myself. It’s also inspiring to set new goals as part of a team. In general, I’ve learned a lot about daily management, from riding to overseeing stable dynamics. Being in this sport involves so much more than ‘just’ succeeding at shows.

What does a typical day look like to you? 

– On a typical day at home at the facility, I usually ride eight horses. A lot of time also goes to making plans and organizing for upcoming shows. 

Do you have a particular type of horse you prefer? What qualities do you look for? 

– I feel like, as a rider, you need to take advantage of the horse's strengths and work with them. You need to be able to adapt to different kinds of personalities since they’re all different. If there’s one particular quality I look for, I would say that it's the horse’s mindset. You need to feel that they want to fight for you.

You’ve had a lot of success both as a junior and as a Young Rider. If you could give one piece of advice to riders aiming for top sport, what would it be? 

– This sport isn’t a sprint – it’s a marathon. You need to remember that if things aren’t going exactly to plan, it doesn’t mean things can’t change – even if it has to come in very small steps. Keep your eyes on the goal, look forward, and try to find positives in as many things as you can. Appreciate the small successes along the way to stay motivated.

During your transition from Young Rider to senior level, you experienced post-concussion syndrome from several serious falls. Would you like to share how that period affected you? 

– Dealing with post-concussion syndrome was definitely a challenge, especially because it is so misunderstood. Learning about it and getting the right support really helped with progress, but the uncertainty was the most difficult. Not knowing how or when I would fully recover was hard. With a lot of ups and downs, I am grateful I can keep doing what I love. Being surrounded by supportive people and my horses helped me through it. I learned that it’s really important to stay positive during uncertain times, not to get too stressed about setbacks, and to be grateful for any step forward.

What are the top three moments you’re most proud of in your career so far? 

– I’m proud of a lot of achievements in my career. But looking back, I have to say that winning my youth medals felt very special. For my senior years, I would say that winning the Hermès 5* 155 in Doha last year and also being double clear in my first senior Nations Cup made me very proud. 

How important is it to have riding wear that supports your performance in the saddle? 

– It’s crucial to wear the right gear since I want to be comfortable when competing, so I can focus on my performance and getting the job done. Looking professional is also about feeling professional – and that helps me get into the right mindset. 

What are your future goals as an equestrian? 

– I want to keep building my team of horses and compete consistently at a high level. A goal of mine is also to represent Great Britain in more Nations Cups and Championships.
