I have paid for my London Marathon Berth, and it is going ahead. This is exciting.
I need excitement and lots of positive things to focus on at the moment, because now is a time of real, significant, scary upheaval. Here is not the place for detail.
I will be fine but it’s gonna be rough.
Addit 2300: I submitted my paper to a journal! Yay! hope they accept it!
Demons, dancing, doctorates, debauchery. 
Good luck! (I think the details will become very important later on!)
Whatever the problem is make sure you give it a lot of careful thought! I am struggling a little with my HM plan at the moment, I was having marathon thoughts, but am doubting them now.
Good luck Cilla. Alot of hard training ahead.
