This is probably a question that has been asked to death on here, so I'm sorry if this is an annoying post!
I'm now on W2R3 (still loving it, still suspicious that this can't possibly result in me running for 30 mins). At the start of the week 2 podcast, Laura says that my heel should be hitting the ground first when I run to reduce injury. However I have read in other places that I should be aiming for the ball first or mid foot first gait as it is better for the knees and other joints.
When I run ball first I feel a bit lighter on my feet, as when I run heel first I feel very 'galumphy' (if that makes sense!). I remember someone telling e years ago that I should try running ball first rather than heel first and it instantly felt better. However, if it's gonna cause problems then that's the last thing that i want!!
How do you run? Does it make any difference? Should I try and alter my stride and start running heel first? Any thought appreciated.
