If you've recently had a cancer diagnosis and you're looking to increase your fitness ready for treatment or you've had cancer treatment and you're looking to move more freely,… opt for Freedom in Movement Other than that, as a general guide - if you've been running regularly for more than 6 months then Freedom to Go Further is likely to be the best plan for you, and you can choose whether you'd prefer monthly, fortnightly or weekly updates. If you're not sure then start with monthly or fortnightly and you can switch to more frequent check-ins and plan updates if you prefer.  If you're new to running, returning after a break, or struggling to turn C25k completion into ongoing improvement or lifestyle change then Freedom to 5k is likely to be your best option.
