Hi! Very pleased to read this thread. Thank you all for sharing experiences and commenting. Same case here, I hit for the first time the half marathon distance last Sunday for my long run. Very exciting! The good surprise is that it went surprisingly well the day after (I stretched well and rolled). The bad surprise is that my hip is hurting since yesterday, after the speed work (I pushed a bit). It seems like the problem is with my hip flexors. To be honest I think I felt a slight pain after the speed workouts for the past 2 weeks.
Coach AJ: I was planning on reducing the intensity and length of the coming workouts (next week is recovery week for me), plus adding some specific strengthening-stretching sessions for the coming weeks. Does it make sense? Could you maybe recommend a few stretching-strengthening exercises?
