What it takes to run a sub 3:30 Marathon?

The last running plan that I finished this year was a 22 weeks Marathon plan, below are some stats:

Total distance: 1,388 km
Total time: 136:45:16
Strength training: 1,027 sets total
Fastest avg pace: 4:29 /km
Longest run (not race): 32 km
PBs: 5k @ 20:10

I finished the race strong in 3:29:38 as planned with 1.5% negative splits. I was very happy with how the entire race went, my fueling strategy, and everything in between 😀

I'm now chasing a sub 3 hrs PB. Do you think it's realistic?
What is your next race / running goal?
