I'm really glad to see this thread on here. This is my first post here. I have started training for my 3rd half marathon after 2 years of not running at all, age 48, and started SB P1 at the same time, nearly 3 weeks ago. It was January; the half I want to do is in May, but I have a long way to go! I managed P1 without many carbs, but I've noticed a huge difference in the first week of P2 in how my energy levels are. I've lost 10 lbs in 3 weeks, one inch in my belly and bust, 1/4 inch off my arms, but nothing off my hips or thighs where most of the fat is (saddle bags). The last two halfs, I did not diet at all, and went from 217 to 198 after the second half, over the course of about 6 months. I'm 5'11" and people never think I'm as heavy as I am, but it does affect how fast I can run. My best PR for a half is 3:01. I broke my big toe on a sidewalk flagstone two years ago, after coming home from the lake, training on trails for my first 5k trail run, did not end up happening. The ortho doctor took me off my foot for 6 weeks; said it was a diagonal break, and if it slipped, I'd have problems with it the rest of my life. I didn't run again after that until now. I want to do a local hilly run (half/13.2 mi); and by hilly, I mean going up and back down ridges from a river valley. The best times online are 3:31'ish, so I'm a little scared. One of the hills is 1.5 miles up, so I have been trying to do a 10% incline on the treadmill once/week, until the snow is gone, and it warms up and I can do repeats on a real hill. I want to start out at 200 instead of ending there. I was back up to about 215, and am at 204, 3 weeks in. Ideally, I'd like to break 185, but that is a long way off. I'll be happy to begin more serious 12-week training in March at anywhere under 200. Also the last time I got that low (185), I was dieting on Weight Watchers, and I rebounded so fast, I ripped out a few pairs of pants.
That was about 9 years ago, and this is the first time I've dieted seriously since then. But I had not started running then, and had no long-term goal other than to lose weight. With the half-marathons, it stays off a little better. Anyways, glad to be here. If anyone else is running this spring, I'd love to compare notes!
