  • 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
