Good day.

I'm 55 and I've been running for a long time, my usual distance is 10-15 km and 21 sometimes. My average pace is 6:15 min/km. I do interval running sometimes as well.

Now, I want to run my first marathon. Is it enough to run 10-15 km every other day at a slow pace without ambition (I can talk during running) or is it advisable to move on?

Thank you.

Good day.

What's a good running pace for a half marathon 2 weeks before the marathon race: marathon pace or usual training one?

Good afternoon.

What should my heart rate be if I'm 40 years old and my pace during long-running is about 4 min/km?

I like to run a lot but slowly (6:30 - 7:30). I don't want to run faster but I want to run farther. I've completed a marathon and I'm going to run an ultra-marathon.

Is it enough to do long runs and strength trainings or not?

Good day.

Is it possible to reach a pace faster than 4:00 minutes per km in 1-2 years of training.
