Too much

Rocked up to hills this morning and called it after 6 reps absolutely knackered. Legs so fatigued and sore just couldn't do anything how to the pros run so much. Decided just to drop back to running 5 days an cross train on the other 2 days. I'll be able to get quality in then over anything else and I was running my best while doing that a couple of months ago. No more 7 days running, the plan is 5 for now and see if I can run fast and not be so exhausted constantly.
