What unhealthy food makes to your running

Today I started by register my minimum heart rate. It went down to 40 for a couple of times during the 15 minutes I recorder lying on the sofa. Here’s the heart rate data. Last time I tested it I had a heart rate of 42, I believe was in the Summer of 2009. So in my case I’m not sure that the minimum heart rate is a very good indicator of how good fitness I am in. I know I wasn’t very fit by then 😀

During the afternoon the only things I ate were a piece of Strawberry cheesecake and one half pizza. That really showed at my run session one and half hour after the pizza.. The past few days I have eaten exactly how I should. And at those days I have felt light, strong and powerful – today it was morelike heavy, slow and tired.. And on top of that my heart rate rushed. I for one believe that it was because of the unhealthy food. I got all the calories, just of the wrong type :S

I’m talking with coach now about how I should plan this week.. Is it going to be another start of a sub 40 program or a build up? I have decided to have my first race at March 21 instead. That is four weeks from now, and it’s the seeding race of the Gothenburg half marathon. I just read his response – It seems this week will be a build up week, and then I’m up for the sub 40 again 😉

  1. I can believe you felt heavy so soon after that pizza 😉
    I need to wait mminimum of 3 hours after a proper meal before I can run, otherwise I get major cramps. In the morning I often just have a small fruit and spoonful of honey 2,5h before my run. I feel that I need to plan my eating quite cafefully before running otherwise it is just too uncomfortable, or painful. Enjoy build up! //Cursor

    1. Usually I go out running within 45 minutes to 1,5 hours after dinner. I thought that was why I had problems with my digestion, so I tried waiting until late evening with the runs for some days – didn’t work either, so I realised the problem was something more than just that. 🙂

      But it’s strange, I’ve heard many people that have trouble running a short time after a meal and yet most advices I’ve found about running and eating says that one should eat a big meal at least 1 hour to 2 hours before a run.. :S

      Thank you!

  2. I never eat anything heavy before my run, even when I used to run at night. Back then I used to eat a turkey ham and cheese sandwich before and a nice plate of pasta after. Today I eat my usual breakfast (bread with butter and milk with chocolate) before and after I blend frozen banana with milk and other stuff (I still have to make a post about it!). So, I don´t have to worry when I eat pizzas and burgers. 🙂

    1. 🙂 Now my stomach works much worse than it used to, but I have always been brought to my knees of bought pizzas. When we make them at home it’s much better.

      But now I try to keep my fat intake at 25% of total Kcal intake, which usually means below 70 grams per day. It’s hard work, but it’s a test to see how it works. I’ve read that that should be ideal when being a distance runner 😉

      Take care!
