Testimonials

Having Coach Mary means your progress is monitored in real time, not just through data but also through how you are feeling. So you know you are on the right path. Unlike an app or generic plan, Coach Mary adjusts based on your state, whether it's fatigue, motivation or external stressors. The accountability factor is also huge; knowing someone is checking in makes consistency easier and training more effective.

Felicity, London
I haven't used any apps before but the reason I opted for Coach Mary was to be able to tap into the experience of someone who has done the style of races (I'm training for) before, and can provide a personalised plan based on my set of circumstances. Mary can alter the plan if there are setbacks such as sickness or busy work/life schedules. And accountability is a big driver too. I've always struggled following generic plans before.

Colin, London
I've found Mary incredibly useful. Having tailored knowledge and feedback on tap, as well as someone who can be reactive to unique situations and very simply, someone who holds you accountable. She is diligent with her programming and has helped me develop as progressively and sustainably.

Peter, London
I've had the pleasure of training with Coch Mary for the last year, and the experience has been nothing short of phenomenal. Mary's running knowledge, in techniques, nutrition and injury prevention is top-notch. She has a unique ability to pugh you beyond your perceived limits while ensuring you enjoy every step. The personalised training plans have helped me significantly improve my speed, endurance and overall performance.

Ben, London
What sets Coach Mary apart is her genuine care for the individual she is coaching, and her passion for running. She is always available to answer questions, provide feedback, and offer encouragement. She has helped me develop skills in how to analyse my perfomances to enable me to learn from every race. I highly recommend Mary to anyone looking to improve their running. You won't be disappointed!

Jess, London
I couldn't have done this without Coach Mary. Huge Thank you for getting me to UTS. I remember telling Mary 8 months earlier that I "just wanted to finish the race"... well we smashed that goal! I felt great and in control the whole way... needless to say I have signed up for my next races already. Lets go Mary!

Will, London
