Hi! My name is Aya Sinay.

Although my official name is Alena, my friends call me Aya. I lived abroad for 12 years.  My home countries used to be Bahrain, Dubai, London area, later Lanzarote and now I settled in Slovakia, from where I travel and work remotely. I have an amazing family and I am a mother of wonderful twins, daughter and son. I have committed my life pursuing my greatest passion, sport.
I started triathlon as an amateur beside the hectic work as a flight attendant.
I am the fastest Slovak female triathlete with a time of 9 hours and 6 minutes. Previously AG World champion in long distance triathlon. 
Since 2013, I have been actively coaching triathlon, swimming, cycling and running.

Thanks to my wealth of experience and constant self-development, I am excited to share my energy and know-how  to like minded athletes who strive to be the best in all aspects of their lives.

To be successful in sport, you need to have the right energy, support from your loved ones, an amazing match with your coach and 100 % trust in this cooperation.


We will work together if  …

  •  You set no limits to yourself, only excellence is the standard you strive for
  • Your enthusiasm and dedication for self-development drives you to make continual investments in your own potential
  • You are a professional or an amateur triathlete, who dreams about finding your true potential in sport
  • You are a total beginner feeling lost in all what you hear, see or read. We will get you on the right track from the beginning

What my clients said

Two Ironman 70.3s and 4 Olympic Distance Triathlons, a World Championship spot and some podiums. I couldn’t believe I could get fit and better at this age. Thank you.

Aya has given to my training a sense of purpose and direction. She has propelled me forward, not only in performance (at my level) but I also think I’ve learned to train more intelligently.
