I've been running for about 15 years with many breaks for mild injuries. (I've learned I have loose joints) I did a half a few years ago and wasn't as prepared as I should have been. It was all up and then all done hill.

Now I'm training for a mostly flat marathon for the first time. I've been really working on my heart rate and gaining mileage more comfortably. I ran at max HR for basically all my training previous to the half I did a while back. I've learned a lot and my cardio health is improving. I'm just worried I'm not getting enough miles in since I'm working HR only.

Week 9 and I'm doing about 14ish miles a week. I would love to hear your thoughts. 42F, ehlders danlos so I do a lot of PT to support my running.
