TL;DR
This was a shorter hilly run that came in 48% below your recent distance average, but at a slower raw pace because of the terrain. Effort was still fairly high: avg HR was down vs baseline, yet most of the run sat in Z4-5 and GAP suggests the flat-equivalent pace was about 6:10/km.

Wins
Held 6:28/km on a hilly route with ~29.7 m/km climbing, and the estimated GAP (~6:10/km) shows the terrain accounts for a meaningful chunk of the slowdown.
No HR drift and no load spike: effort stayed controlled across the run, which is a good sign for aerobic stability and progression.
Watch Outs
The intensity was still high for a short run: 75% of time in Z4-5 means this was not an easy aerobic day, even though average HR was below your recent mean.
Cadence at 81.2 spm looks low for the effort and terrain; if that reflects actual steps/min, watch for overstriding or unnecessary load on calves/shins on future hill sessions.
