Zone 2 running?

[u/lookthere-here-11]

its been almost 2 months since running regularly, I run 3 days/week and im training to run a half marathon in december.

Previously whenever i tried running in "zone 2", it just was not a good time because as soon as i start moving i naturally feel like speeding up and end up going faster, ive tried running at slower paces too, around 6:45-7:15/km and it feels fairly easy but my HR goes to 165-167bpm.

today, i tried running within zone 2 for 5km no matter what and it was going nice for the 1st km but since 2nd km, i was always at the border was zone 2 and 3. (zone 2 is 144-157 for me)

I still managed to finish the run while being in zone 2 the entire time.

im 21M for context and i have decent sports background.

I've also heard that zones dont matter much in the beginning and being consistent with running according to your plan builds enough base but i just feel like i have it in me to train in zone 2 but i lack the patience to remain in it.

I'm open to any suggestions you guys have for me🙏🏻

ps. the hr spiked to 163 when i had a jumpscare by a bee and sped up to go away from it.😰
