A slow and painful mile run but I'm back outside

I booked half marathons in September, October and March because without that I would have no motivation. Before this morning, I had only run once since London. I have been to some classes but not as much as I could have. Last week, I only lasted 20 minutes in Circuits because of my lower back. 

Additional reasons for not running:

Ofsted

Workload

I was finishing my Uni assessment 

Too hot - mini heatwave at the moment.

The cause is my tight hamstrings, inflexible back, tight hips and weak glutes. I have ordered a belt for my back and a flex stretch. I have also downloaded a flexibility programme to help. I need to book in another sports therapy session with Emily. 

This morning I managed to get up earlier enough for a run. However I only managed a mile running as my lower back was hurting so I walked. I am okay with that though as I did get up early and go.
