I'm training for a 5k, critique my routine.

Ok so over the past few weeks I've been working on getting in some sort of proper shape, I do this every so often, it usually ends in me completing a goal then getting out of shape again. So this year I set a few goals instead of just one. Main goal? Complete a full marathon. Step 1: Complete a 5k next month without finishing in the bottom 10. I've been dieting and exercising, I have never done both at the same time before, over the past few weeks I have gone from 365 pounds to 339, I expect after this month I may be sitting at 300. Please note that I do not have a problem with sticktuitiveness when theres a goal in mind, I will complete every minute of every day of this plan, unless something changes based on advice that I get.

The middle of the pack times for the same 5k last year were 9 minutes per mile on average. I have run 10 miles averaging 10 minutes per mile before, that was last year. So this should be extremely doable.

Heres the plan, give me some feedback please even though its not specifically for boxing.

Ok thats what I got, I should be able to handle this load without injury, question is, is it enough? Anyone see any flaws? I'm on day 2 completed and sitting at 5'11 height and 339 pounds weight wise. I have a 10 minute mile and a 12 minute mile so far with 2 miles done at 25 minutes(that sucks I know). My goal is to hit a 9 minute mile and sustain it for 3 miles. I have a marked off route, a heavy bag, a round timer, a stopwatch, and some running shoes.
Thoughts?

 

I actually thought this schedule was easy, I do the heavy bag so I can keep my cardio up while my legs rest and repair from running. I hit the heavy bag almost every day for 3 rounds just to be active anyway.

I'm only a year out from last time I did 10 miles in just over 100 minutes, so I actually thought this was starting slow. I can't believe I run so slow now, I've always had a very short stride and work my ass off to make less than 10 minutes on a mile, im trying to increase my speed without killing my knees, Ive never had knee problems but don't want to start now.

 

Yes I'm 340 but please don't think i'm some couch potato, I'm the most active person I know

I did the Forrest Gump thing last year and ran everywhere I went, 2, 5, 10 miles, didin't matter, and I never dropped below 350 pounds. This time around i'm dieting too, I think if I ever hit 250 I will be able to stay there. I can't imagine being under 250, id feel..small.

The most out of shape Ive ever been was when I fought in toughman, 1 and a half rounds, and I was looking for the hit to go down to, puked like 5 times after the fight. I'd like to try it again in better shape

 

Thanks for the encouragement folks! Completed my rest day today, but I accidently ended up running about 1/4 of a mile(adrenaline induced sprint) my lil bro and I were walking in the woods and got on someone elses property, they came running after us yelling, even though we had high powered rifles and a 12-gauge shotgun we hauled ass to avoid trouble, we knew we were in the wrong but still didint want any bull**** lol.

Afterwards I was like "**** I wasent supposed to run today".

I'll keep updating here, if nothing else I know if people are reading about it I'll be more likely to maintain it.

 

Finished a little more than three miles today, the fact that I can actually run 5k this early on is encouraging, now I just need to get faster.

Anything I'm not doing here that could increase my time? Or is it gonna be practice+weight loss+stamina all the way?

Also my friend who used to run distance in high school was telling me something about controlling breathing, something like two breaths per step or something. Any enlightenment on this?

 

So should I make my diet more strict? I currently eat between 2000 and 3300 calories per day. I know I'm burning more than that. I even tried to do a cheat day the other day for metabolism and when I added it all up it came to 3500 calories.

I know crash diets fail in long term weight loss, but for the sake of a better time in this event, should I maybe cut to below 2000 calories every day to drop weight and add speed? Or will the malnourishment hurt my speed and training performance more than the weight loss helps?
