I do 5-10k runs once or twice a week. While my legs inevitably get tired, last time they felt unusually heavy before even hitting one kilometre. Especially the ankles which felt solid rock.

Last time this happened to me it was because I didn’t eat enough beforehand.
Usually I eat a decent lunch then go for my run a couple hours later - maybe eating a banana 15-30 min before. That day because there were thunderstorms forecasted I skipped lunch and just had a banana and a cliff bar before my run. Got tired pretty early on that day.
Perhaps the body builds certain habits. I go for a run in the early morning on an empty stomach. Always been the case.
