If you've selected a '12-week program', these are 12 weeks long. If you've selected 'Tailored Running Coaching', these can go for as long as you like, there is no minimum and no maximum. You will get a new fortnightly program uploaded to your Final Surge account every 2 weeks for as long as you desire and continue your payments. If you find it's not for you, cancel after the first week, if you love it and wish to continue, just continue making payments and we will continue to work together. We recommend sticking with the coaching for a minimum of 8-12-weeks to see any improvements.
