I started to running as a 3 days a week train a month ago, I did a 5k run to know, and my time was 32.30, I want to get it down to 27 by the next race in 2 months. I'm doing 2 heart range trains and 1 pace every week.
I’m not sure what’s the best heart range for me, I'm 20 years old, 90kg about 200pounds, 173cm, when I run my heart go to 180 in an easy pace, and in a sprint it gets to 210. In a calm walk after a run it goes really fast to 140, in 40 seconds or so.
So, is it a good training to sprint every time i can get back to 140? So I stay always in a tough situation. Or should I stay in the 180 with a slow pace?
Ill ad any information as needed, thanks for the help.
