hi , i have been running quite awhile and i would like to ask for some advice regarding running....
Is it true that i should train in zone 3 for a long time in order to achieve faster pace at a lower heart rate and also endurance ? before getting a garmin watch , i ran with my phone with 6:40-7.00 minutes per km pace and not knowing what my heart rate is. So i got myself a garmin watch after running for quite awhile, i ran with my usual pace and found out my heart rate was reaching 190bpm (that was high considering i am 20 years old). I usually run 6-8km every time and rest for one day and continue the day after that as i feel a little bit tired ( perhaps my heartrate is high?)
So my question, how am I going to run faster at a lower heart rate? In order to stay within zone 3, i have to run at pace 12:00 and that was like walking.... Perhaps some experts could advise me on my running routine ? Thanks!
Different workouts provide different stimulus. There is no such thing that running at a certain zone will help you run faster at a lower HR. I don't know what zone 3 you're talking about because everyone running coach has a different definition of zone 3.
Easy running helps you increase your aerobic endurance. Mitochondria, Heart stroke volume etc. It's a cliche, but if you're easy running, then you should be able to hold a conversation when you're running. With easy running, you shouldn't need one full day to recover.
Running faster helps you run faster. There different workouts could be strides, sprint reps, hill sprints, tempo runs, cruise intervals. v02 max intervals etc
Aerobic fitness is a volume thing. The more you run the more aerobic fitness you will will get. The problem right now is that you're only running 3 times a week on 21km a week (2hrs 15 mins?) on average and that's not a lot. A few things you can try with this easy running thing. Run based on time not distance - try running 30-35 minutes a day. Have one long run day, at your volume 1 hr is fine - by doing that you're already running 3+ hours a week if you're running 5 times a week. That increase adds up over time. The whole idea behind running easy is to increase your volume by taking less rest days. You don't have to run so slow until you're walking, just slow enough that you can have a conversation - with yourself and you don't feel so tired that you need a break the next day. This is effectively called base building.
A few weeks of doing that and you can incorporate speed workouts into your routine.
