My collage is planning on going to London in July for nearly the whole day and its going to be a lot of walking. I suffer quite badly with leg pain, often having to use a cane or wheelchair on my bad days. I also struggle to keep drinking throughout a day so I know if the day is hot, I'll struggle a lot more than I need to. So I was just wondering if anyone has any advice for long days out? This advice can be different walking strategies, drink recommendations, or snack recommendations

Thank you!
