This all looks fine to me. HR training it super simple, you just want your heart rate in that zone. I don't think taking breaks is going to have a big impact at all.

Objectively, the best thing you can do is lose some weight so running becomes feasible. That 10 mile walk is a great idea, but it isn't really training your aerobic system.

You might also want to add in some "extra" stuff. For ultrarunning balance, strength, and coordination are all essential. There's tons of resources out there to help you build a program, but I'd recommend mixing it in now. If you can commit to it before you start running you have a really good chance of avoiding injuries.

I'll briefly go over some crosstraining basics, these are just my opinions. Most athletes are good runners, but most runners aren't good athletes. IMO this simple fact explains why 80% of runners encounter an injury sometime in their career. If you want to race ultras the safest way to do so is to start treating yourself like an athlete.

1. For strength training, go low reps high weight. Runners don't need tons of muscle mass, but the muscle they have needs to be strong. This can be dangerous if you lift without proper form so with movements that feel easy. I wouldn't encourage you to jump into squats and deadlifts if those feel uncomfortable. The leg press machine, bulgarian split squats, weighted lunges, and calf raises are good examples of simpler, less stressful movements. You don't need to do a ton of sets of these, or even do that many of them. I normally lift 1-2 times a week, doing three sets of three exercises for 3-5 reps.
   
2. Hate weightlifting? No problem, bodyweight exercises are also awesome. David Roche's 5 minute mountain workout is a great example of an unweighted routine that works your balance, coordination, and musculature. I would strongly recommend working some bodyweight stuff into your routine. Anything on one leg is awesome, anything involving squatting is great, and anything that challenges your core is great. The more muscle groups you need to recruit the better
   
3. Actually finding good exercises can be daunting. A good starting place is Jay dicharry's anatomy for runners. It'll help give you a handle on the strengths and weaknesses of your body, and start you down the path to improving them.
   
   This is an ongoing process that'll follow you across your career as a runner, but stick with it and I guarantee it'll pay dividends.
   
   One other note. Because you haven't started running yet you haven't had a chance to make the mistakes most novice runners run into. I'll list those out briefly, this is just what I've seen in myself and other runners.
   
   

• Slow cadence. I was running with slow cadence for years, and it caused all sorts of problems with my stride. I was bouncing too much which stressed out my calfs, I was leaning to the right which stressed out my quads ect. Cadence is a personal thing, but generally you should try to stay above 170 steps a minute.
  
• Bad programming. The number one way runners get injured is too much too soon. Adjust your weekly mileage slowly and be patient. The best way to get faster is to slowly build up your mileage without getting injured. You're doing a ton of aerobic training now but that's not running training. When you actually start running I would recommend doing couch to 5k, then taking it super slow from there. You have a whole running career infront of you!
  
• Poor glute engagement. Buy that book from dicharry, it'll go into better detail on this than I can. The long and short of it is many runners don't engage their glutes when they run, shifting more work to the calves and quads. This slows them down and makes them way more injury prone.
  
  Good luck!

I haven't read it, but I would check this one out: https://www.amazon.ca/Koerners-Field-Guide-Ultrarunning-Ultramarathon/dp/1937715221

I have read "Daniels' Running Formula" which is very very good: https://www.amazon.ca/Daniels-Running-Formula-3rd-Jack/dp/1450431836/ref=sr_1_sc_1?s=books&ie=UTF8&qid=1469153523&sr=1-1-spell&keywords=Daniels+runnnig

I also recommend "Advanced Marathoning" which is a better all purpose "how to be a runner" book than Daniels, but a bit less scientific.

Both have training plans for beginners. And like people mentioned: getting good quickly is easy... it's not getting hurt that is tough!

Skurka is better known as an ultralight backpacker / adventurer, so he has an interesting perspective on ultra running.

Edit: he finished at 37th place in 7:26
