Just wrapped up a 60 minute spin on the trainer. I can tell my body is becoming more efficient in transporting oxygen. It's taking less and less effort to do the same workouts. I'm still a little intimidated by the hill training that's to come, but I'll climb that hill when I get to it (boo).
As an aside, I've been thinking about what I want to accomplish as a runner, assuming my (relatively) old body holds up. I mentioned before that my best time in the mile was 5:01, back in 1985 when I was a senior in high school. It torqued me off to miss a sub-5 mile by two seconds, and to be honest, it still bugs me a little (not that I'm losing sleep over it). I've been wondering if I want to take a stab at that mark again. Could I break 5 at my age, with the proper training? Probably. Should I attempt it? I don't know. With my history of injuries, I might be asking for trouble. I don't want to become obsessed with physical goals and tear myself up trying to achieve them...yet goals are what keep me (and most others) going. I'd also like to run a marathon...and do a century ride...and probably a few more things that escape me right now. I think the best approach is to have some long-term goals that are pretty daunting, but have several "mini-goals" that are more achievable, on the way to those larger goals...and try to keep everything in perspective. Should I never run a sub-5 mile, or even a marathon due to injuries, I need to be able to live with it. But I'll be doing whatever I can to keep my body strong and uninjured as I pursue them.
