Went for my latest run on Wednesday, June, 17, and I have to say I can feel my lungs getting stronger. My legs weren't in the least bit uncomfortable, tight or sore both afterward or the next day. I feel like I'm making a lot of progress and should be able to do a 5k or 10k at some point in the near future.
This run was shorter than the last--a quick 2-mile run that I did in 18 minutes (give or take a minute.) That puts my mile average, with the hills included both heading out and coming back) at 9 minutes--certainly not a great achievement for a runner overall, but a great achievement for me, as I have been able to maintain this without stopping and have shaved at least four minutes total off my time from when I was running this last year.
My goal is to be able to do this run in 15 minutes flat. I think 7 1/2 minutes is a great average for a mile, running both uphill and slightly downhill. I'd like to be able to do it sooner than later, of course. Hopefully this summer while being outdoors and exercising a lot more than I was both last summer and all of last year, that I'll be able to shed my winter weight and recent running slump.
I remember the days of high school when I did the mile in gym class in under 6 1/2 minutes and was commended by the gym teacher for improving my time greatly--and I didn't feel winded at all after finishing. In fact, math class was still a cinch afterward.
