Cardamine raphanifolia(?)

Cafe church this morning and a good turnout for an interesting service.
Did some cross-stitch and then decided to go for a run, it was dry and blustery by then, and got round very slowly as my legs were pretty stiff after yesterday's exertions.
Went via the ponds where this is growing at the edge, I think it's the greater cuckoo flower, that's what I've recorded from when the ranger identified it
