Very awesome, OP! I started running myself recently; for a while I was avoiding the treadmill and just staying on ellipticals because I have a very bad knee, but I got a good brace and started at it a few weeks ago- Im 31 and its the first time in my life that I straight ran a mile (in 12 minutes )
But I'm down to 10:47 more recently and making improvements every week.
The best part about starting late is that every try is like a personal best I think
"Ah, those endless forests, and their horror-haunted gloom! For what eternities have I wandered through them, a timid, hunted creature, starting at the least sound, frightened of my own shadow, keyed-up, ever alert and vigilant, ready on the instant to dash away in mad flight for my life. For I was the prey of all manner of fierce life that dwelt in the forest, and it was in ecstasies of fear that I fled before the hunting monsters."
