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?
The only thing I haven't seen people mention so far is breathing.
Make sure you are doing breathing exercises and that you can keep your breathing under control for your whole run. Once your breathing goes everything else will fall apart.
I'm able to breath in through my nose and out of my mouth for the entire run, nearly every run. I'll have to look up anything else.
My weight training coach used to tell some of the guys to 2 two regular breaths in through the nose, then one through the mouth. Couldn't hurt to try. Good luck friend
I use the nose-breathe-in-for-3-steps and mouth-breathe-out-for-2-steps which seems to work for me. If I find myself struggling and notice I'm not doing this then starting seems to calm my breathing again. I can just about do it without thinking now. I definitely struggle with the leg stamina thing though. Only been running regularly (3x week) for 8 months.
Thanks. I've been using one breathe in and out every 4 steps.
