This is yet another big improvement from my previous PB, however I can definitely shave off more time except it will be more challenging from here and hopefully I can get the 1:50:XX soon.

Note that I re-timed this before submitting, I started the timer 19 milliseconds early and with a final time of 1:52:22.09 this brings the time down to 1:52:21.50 (with milliseconds). Please feel free to re-time at your own discretion.
