James says:“I think the plan is a great place to start for many people but it is very generic and doesn’t really take into account your age, fitness level,previous exercise history,and many other factors that can influence your ability to run a 5K.”
“As it is not individualised,it may work better for some but not for others.People who are older,have a minimal history of exercise,are in general poorer health,or have a higher BMI, may struggle with the speed progression of the Couch to 5K.”
