Running 5:00 
No issues today.
Did a bunch of googling itb things yesterday, including running form and its possible impact on itb health. So, today tried implementing some tweaks: More leaning forward but while remaining upright/tall, landing midfoot with the foot under or behind the hips. Not sure I was actually implementing these things right -- it felt like my knees were hardly bending compared to my normal way of running -- but actually, it felt pretty comfortable.
Planning to go for an actual gait analysis too, such as to see about shoe type. Trying to pull out all the stops in the hopes of not having a recurrence.
