I think I need glasses

As per usual I go for a run in the botanical gardens most mornings, this morning being on exception. I was doing my stretch outs while looking for some eye candy to jog behind as usual, I mean why wouldn't you. When I spotted a tall athletic girl coming off an adjoining path, she was jogging rather fast so I had to put on the pace to keep up with her. As I was starting to close the gap I was admiring her long strong legs and sexy tight bum and exposed shapely waist. She was wearing loose small sports shorts that exposed her bum cheeks with every pace and a crop, OMG she was so so hot. Anyway as I was about to pass out from exhaustion as I was struggling to keep up with her I started to thing why she looked so familiar. Then the penny dropped, I was chasing my ex. Although I was on my own I felt really stupid, I stopped and sent her a text (look behind you) as she was disappearing into the distance. About 30 seconds later she came back into view, we finished our run together and had a coffee, I didn't tell her about what had just occurred, glasses it is for me.
