I am high school male distance runner who is 18 years old and I recently ramped up my mileage to around 50 mpw for the track season and I’ve been reaping massive fitness benefits. I do 12 mile long runs weekly comfortably at around 7 flat pace and have been setting lifetime PRs this season. (10:41 in the 2 mile and ran a 5:00.6 in the mile last Saturday).
The only problem with ramping up my mileage is that I’ve noticed I’ve been losing weight. I am 5’8.5 and my weight has dropped from an already underweight 112 pounds to about 109.5 pounds. I wasn’t that worried about how light I was getting up until I saw number drop below 110, THATS when I knew it was becoming a problem.
Although I’ve gotten this light my running has been surprisingly going well as of late. I recently set a lifetime PR in the mile of 5:00.6 and ran a 10:41 in the 2 mile earlier this season. My running cadence has been noticeably much higher this track season as opposed to previous seasons. It used to be around 160 or even below that and now it’s up to 165-170 depending on how fast I am running. So I haven’t noticed and negative signs in my running and workouts as I have had great workouts so far this season with no signs of crashing and burning and my long runs have also been going great as well.
I do notice that throughout the day at school I often feel quite week, almost like my arms and legs feel tired most of the time, but when I run, it gets better most of the time. I also notice that sometimes I often feel lightheaded and dazed while sitting in class.
And as far as diet goes, I am eating about 3 meals a day and it feels like a lot of food, but I notice that when I come from school after practice, lifting, and not having eaten since lunch at 11:00, I am extremely ravenous and feel quite agitated and hostile until I eat dinner, and that usually ends up being my biggest meal of the day.
So what can I do to gain weight while still improving my track times this year? I’m feeling good with my running at the moment, but I don’t want to cause myself any future harm to myself that could negatively impact my running in the future.
