I sent this as a PM to someone on this forum who was having issues.
I’ve gone through this for 4 damn years. I’m a top 5% swimmer in my races and top 10% cyclist, but im so far behind on running because of this injury and it affecting me every year.
I’ve tried EVERYTHING. Every google search you’ve done i’m sure I’ve done too.
i went on a ridiculous rest, strength and stretching program. I probably have some of the strongest hips and glutes on slowtwitch. lol. Side leg lifts, squatting over 200lbs, deadlifts, single leg squats, clamshells, band walking, abductor and adductor exercises, and a ton of stretching – I even changed my desk at work from a sitting desk to a standing desk.
The pain went away all year, I was so happy… best training i’ve ever had…
Until my first half ironman where 10k in it came right back, and I gutted it out in incredibly pain with a 2:05 split and it ruined my year. I was so furious.
It was then I realized i had to change something. It couldnt be strength or stretching, i can’t get any better at those.
It was because of the way i run when my legs get fatigued. It was the only answer I could think of
The other day I saw this blog post, and thought it was pretty good

Yes, that site is selling something but please ignore that.
If you read what he talks about (its not friction, strengthening or stretching), but the fatigue state of the running, and a change in running form, this is what finally helped me.
i keep my legs more infront of me with an earlier knee/foot lift (i imagine a glass wall behind me and dont allow my foot to break it). The way i followed through when tired was somewhat ‘lazy’ and i kind of dragged my foot infront of me which used the IT band slightly, just enough to do it thousands of times and make it hurt.
to get the feeling of the technique, i practice running fast uphill, it’s a similar feeling in form mechanics with more knee drive infront of me, not behind me.
I just thought I’d mention this to you. IT bands are such a bitch and maybe yours IS to do with strength and stretching, but this is what helped me. I still do the strengthening of hips/glutes, but i don’t stretch or foam roll anything to do with my IT band anymore.
good luck!
