Ditto on the gym (also wing chun and taiji), "only" about 30k miles but the knees doth protest too much. Meniscus OK but tendinitis inflammation flareups...ugh I truly love to run.
I came to running a bit later in life, not that I'm an old man (no matter what my kids might tell ya'). Got diagnosed with T2 Diabetes about five years ago or so and decided I didn't want to be on medications the rest of my life, and I certainly didn't want to be one of those guys who drops from a heart attack and everyone at the funeral whispers "so young ... how does something like this happen? His kids are still young. How terrible." My doctor suggested some diet changes and jogging.
My first day as a "runner" I confidently put on my new running shoes, did some jumping jacks, and headed out on the road. About a quarter mile later I hit The Wall lol. Talk about humbled!
I am not up into those numbers like you or @SPYgrain. But I'm now doing two runs per day - morning wake up and evening after dinner (just got back in now), and each one is now over 5 miles. I average 10 to 11 miles/day between the two. My goal this summer is to train in order to run my first half marathon at a local charity event in September.
Truly an addictive activity. Yesterday morning it was pouring rain, the roads had two inches of cold running water or more in some places, and while I'm a fair weather golfer, I wouldn't miss one of my runs - rain or shine.
