Heel striker - should I change?

I’m a natural heel stiker. I’m trying to work on my running economy and thinking of trying to be more of a mid-foot or forefoot striker. I haven’t consulted any coaches.

Should I stick to my natural heel strike or try move to mid/fore foot strike.

My PR’s are: Marthon 3:27 IM marathon 4:04.

Cheers,

Will

Best advice i got from Gordo was not to change but to “shorten stride and increase cadence”. I now run better and more injury free, for example before i was a big heel striker at around 78-80 cadence and now am at 84-86 and strike some what midfoot.

Thanks for the advice. Just what I was after.

Cheers,
