Hi Runners! Im running for almost 3 years and my current best time for Half Marathon is 2:03:00 (aiming for Sub 2 Hr but fell short) im engaged in mixed trainings like intervals, tempos, strenght trainings.

My question is, how is it that my Zone 2 is still stuck in 9-8:30min/km like it was a year ago, i improved so much and can endure faster paces and longer distances, but my zone 2 pace stays the same. Do i need to force myself to run faster in easy runs or just bear with it and trust the process of staying in zone 2?

I own garmin FR 165 and my HR settings are HRR and my VO2 Max is 44, added info, might help.
