For me, the right ITB has always given me more issues, and I think it's a strength issue mostly - my right side does most of the work propelling me forward and gets worn out faster at least on road races.<br><br>
However, on a trail run, you need strength from both legs depending on how technical the course is. I did my first 25K first time and also on a muddy course to boot and the weaker left ITB went ballistic around mile 12.
