rdtompki, I find myself in a similar situation, and it certainly is a good feeling!
Although I cheated with the weight loss routine and had bariatric surgery in 2009, I lost exactly 120 pounds and dropped from 284 to 164, which is four pounds less than I weighed in 1958 when I got out of Air Force basic training (where I’d gained several pounds after learning to appreciate military food).
I gained back about 10 pounds over last winter due to inactivity, and my focus now is to lose most of that and maintain a weight of about 168-170 pounds. I am 5'8".
My weight maintenance plan includes riding about 20 miles every day (with 40 miles being my maximum comfort zone), and although I realize that’s not many miles for most dedicated riders, I’m pleased with it and confess to feeling good when non-riders express disbelief that someone my age can ride that far.
Aside from the weight issue, the riding has enabled me to be more active off-bike than I’ve been for more than 30 years. I now walk everywhere I can, even to the extent of leaving my car at the far corner of a store’s parking lot so I can enjoy a brisk hike both before and after shopping. I take on chores and projects around the house I haven’t EVER done, and my wife of 55 years is very happy with me!
