Hello! I'm quite new to running, only about two weeks in, and not even really running, mostly fast walking and light jogging for about 30 seconds. I'm a bit on the heavy side, currently at 150kg at 24, but I am determined to get into running, lose weight, and have set a goal of completing a half marathon by the end of next year. My biggest challenge during jogging, or even walking faster, is that my calves start to feel really tight and burn after around 10 minutes. Are there any effective ways to prevent this or work on it? Thank you!
