So the point of this thread is to say this:
If you're one of those people who says "If I go over 30MPW I get injured every time!" You're wrong! Just run a week of nothing but easy doubles and once you've done that before you know it you'll be running that same mileage with 2 hard sessions and some gym work thrown in.
Good for you and perhaps true for most people, but you are overgeneralizing as not everyone’s physiology is built to tolerate mileage.
If you’ve been on this forum a while, you probably know spambot david45. If not for his spamminess, I’d totally relate to his experience coz I’d constantly getting injured at very low mileage like 15-20 mpw.
I finally realized that I had bilateral calcaneal stress fractures, but the pain would quickly subside to almost nothing in a week or two and I’d resume running for a few more weeks only for the cycle to repeat, which all finally became clear through MRIs. I don’t know how I could run nearly pain free with the MRI showing a stress fracture hairline but it is scary to think that pain wasn’t a reliable signal.
I did some more analysis and found through a DXA scan that I’m nearly osteoporotic in bone density, which could explain the vulnerability to stress fractures. My nutrition isn’t a problem as my nutritionist also confirmed, so I’m now doing weight training and considering medication for improving bone density. Before I started running, I had no idea I had any physiological issues and had always been in great health and (non-running) fitness compared to even younger adult peers.
Bottomline is I’ve been very dedicated at running (which is easy if you love running like most of us here do) for over a year and learned the hard way that it’s just not as easy for me to increase mileage like most everyone else.
