Good gym, real progress — but easy pace feeling embarrassingly slow at first frustrated me

I've been training Running for 18 months at a decent gym with good coaches. My cadence has improved significantly and I've developed a real understanding of periodisation. trail running scenery has been a consistent positive.

The one thing that has genuinely frustrated me: easy pace feeling embarrassingly slow at first. I've read that this is common in Running but it's still annoying when you're experiencing it. I've worked around it mostly, but it's the reason this is four stars rather than five. The sport itself is excellent — the frustration is circumstantial.
