Running

Question for the experienced runners here: 
I ran my first sub 2:00 half marathon in March and finished my first marathon in 5:00 a week ago (trained for 4:20 - 4:30 pace but bonked hard). I have 5 months to my next marathon, is sub 4:00 a realistic goal?

Do do a sub4 marathon you should be able to do a 1:45/50 half. 
I’ll go first for that, then try the full.

Weekly mileage was averaging 30ish for the last 6 weeks of the training plan, lower before that. 

I am doing intervals 1x week plus 1x tempo, 2x easy, 1x long run. I am definitely down to increase my mileage over the coming months!

Hey, the fact that it’s half the distance increases your odds by a lot! A few questions: what’s your weekly mileage like? Do you do intervals? Are you willing to progressively increase your weekly mileage over the next months? 

5 months gives you a decent amount of time to progress

I think I was ok on fuel (50g carbs per hour) but pacing was def an issue. Went out too fast + didn’t pace well on the early uphill sections. 

I had just one 20+ mile run, 3 weeks out from the race before the taper.

def not experienced enough to answer precisely, but any thoughts on reason behind your bonk? 

did you go out too fast, how many times have you done 20+ mile runs, did you have sufficient fueling during the race?

pacing/fueling (assuming no gut issues) may be easier to take on
