Legs Flick Out When Running

I remember a girl in my HS who was knock-kneed, and she ran like that. Maybe you have some degree of it, and your natural motion is to do this. It's an inefficient style, but better than tryng to do something unnatural. Talk to your coach about it.

Do some strengthening and see if it gets better.

If not: as said, don't worry too much.

Example: Did you ever look at Kendra Schaafs legs when she runs? Bow-legs deluxe! especially in XC! But it seems to work for her!

Check this for proof!

You need a good kick up the backside -you can probably do that yourself!

A physio once told me I had the same problem, but when I did the foot plant test thing on treadmill others said I had a perfect foot plant

Just try and relax a bit and modify you style very slightly. Maybe some leg strengthening exercise like squats - can't do any harm. Your body is made way it is don't try and alter it too much.

I was once watching some horse racing experts on tv analysing video of a horse who was flicking his fore feet up too high when running in previous races. Then I thought hand on this vid is showing the horse crossing the winning post 1st in a race and still doing the high front knee lift thing; the horse can't be tired running like that -straight away I put a winning bet on the upcoming race
