Intro. and question for distance runners
Hi, all! I am very interested in hearing from those of you who are runners, and am wondering if anyone has experienced weight gain with endurance training. I've been running for about 8 years now, but started running longer distances like half marathons about 4 years ago. When I first started running longer distances, I gained a few lbs. that admittedly I needed to...at 5'4" I was about 107 and had been dealing with a series of stomach troubles for years. I landed at 110-112 and had been at that range for several years, and while I know it is still on the smaller side, I felt healthy and strong and was definitely taking in plenty of calories. I decided to take on the marathon distance last fall and upped my running from about 20 miles a week to 40+ miles a week, and that is when the lbs. started to creep on. I was starving all the time and probably got a bit crazy with the carbs., but overall I was still fine with the gain and was at 116 by the end of my training in October. Since then, however, I've continued to gain despite cutting back on calories and carbs. I'm back to running about 20-25 miles a week and typically net 1700-1800 a day, which I think should be an o.k. number for maintenance, yet I'm still gaining weight and am at 120 with no signs of slowing down. Now again, I realize 120 is a perfectly healthy weight but I'm concerned about the trend ...I seem to just keep slowly gaining despite running, cross-training, and eating a mostly very healthy diet (I've been eating about 20% fat, 25% protein, 55% carbs). Just curious if any other runners have experienced weight gain like this?? For the record, I turn 40 in a couple short months and am wondering if this could also just be a "getting older" thing...Does your metabolism really change that much as you age? Thanks for any thoughts...I'd really like to stop the gain at this point, if not drop a couple lbs. so I can fit back into my clothes!
