Ok, just getting familiar with this case, so bear with me. I read on earlier pages, her husband failed to comment - who reported her missing? Dailymail says she was reported missing after failing to return home, so was that her daughter or husband who reported her missing?
I've watched all the CCTV and my thoughts are:
1) This is someone who is in a hurry
2) She knows exactly where she's going (even if we, watching the CCTV, don't)
3) She's in so much of a hurry, she actually crosses a road with a green light on and narrowly misses getting hit by a car, and she doesn't look back - she's determined to get *somewhere*
4) That somewhere appears to be the cathedral
5) After she visits the cathedral, her running/speed has slowed, but she's still very, very determined to get somewhere
6) Her coat is put on as she walks away from the cathedral which to me, indicates she's a bit cold, aware of her surroundings, but it could just be a motion she's used to doing - it's hard to read into that without knowing her personally
7) Going to do Yoga outside sounds...quite frankly very weird in these temperatures. It's hard to make any good analysis of the witness sighting
8) But the witness must be right about the sighting, because her belongings were found in that park
Going to do some more reading and take a look at maps as I don't know the area.
