Lifelong athlete. 37yr old male. College baseball player. Have been lifting weights for 15 years. Very consistent with my diet, in fact I have my diet dialed in and track calories eat nothing but whole foods.
I’ve been running for over a year, off and on due to calf and achilles injuries but mostly on. I am on week 10 of a 20-week half marathon plan.
If you look at me, I look very fit. People assume I am very fit because I have decent muscle mass and I’m pretty lean (around 10-11%bf right now). But I really struggle running. I just ran a 7-miler for my long run and it killed me. A freaking 12:53 pace, started at 5am and finished around 6:30am. I am deliberately running in zone 2 to build my endurance base using my Garmin watch and chest strap. I couldn’t have run any faster if I wanted to. Running so slow but my average heart rate was 149bpm. All of my other health factors are very good. 48bpm resting heart rate. 7-8 hours of sleep a night. Weight lifting 3 days a week. Running 3 days a week. All blood work in January was great.
Before I focused on my endurance I got my mile time down to 7:33 at around 80-90% effort. I just feel like I should have a better base by now and even though building the mileage takes time I feel like I’m way too slow for how long I’ve been running.
Am I doing something wrong? Any advice or feedback for me?
Another random piece to add, maybe it will help you out too - I have ridiculously flat feet. Like literally no arch in the slightest, and it kinda fucked my knees and hips up a little bit. My feet also naturally point outwards when I’m standing too, so I’m wondering if maybe my running mechanics are fucked because of that, and maybe it takes me way more energy to jog than a person with normal feet? But I still don’t really get it, because like I said, I was a faster sprinter than 99% of people I met, only track dudes were faster than me.
Coincidentally, I have small, wide feet.
