When I go to London I always get a hotel located so I can jog Hyde Park. I always go in the mornings at first light - but have gone in the dark. I believe you would be safe in daylight. Although being a man, I don't worry too much. I have seen a lot of solo females walking and running in the park. I set a four mile course in the park and it is a neat place to see different things. There are some signs that give you directions, but since it is square, it would be hard to get lost,unless you became disoriented due to being new there. I know one time it started to rain on me and I got turned around a little, but it was easy to get back on track. I have been in the summer, fall, and spring and have never got hot, but I have gotten cold on a March morning. If you dress right, you will be fine. The paths are nearly all paved and clean. You will also see the workers around the park cleaning up in the mornings. I have never seen anything bad. I really enjoy the park when I am there. The map will help when you first start. Pick you out a couple of landmarks - tall biuildings - monuments - as reference points. I think you will enjoy it. Thanks - Bill
