Dial it down. 

If you got injured going 10% up a week, be more conservative.

I don't know if I get pain. I just can't stand the mushy feeling, so I don't buy or wear them. 

I also have a bad ankle so I prefer low stack shoes with good ground feel. You can't be maximalist and low stack.

I think some questions to ask are, do they know how important this is to you? Are they the types of people who would actually enjoy watching a race (they're boring!), did you mention to anyone that you would appreciate support? 

In general I know the people in my life wouldn't really enjoy coming to a race and spending time watching people running, so I don't bother asking it of them. I get my support through a running club these days.

people say these are the best shoes for flat feet

There's no such thing. Flat or not, everyone has different feet and different needs and preferences. I have flat feet and I can't wear cushy shoes, I only wear neutral shoes with minimal cushioning/a firm ride.

Have you tried couch co-op? Or any party game?

In general it's not particularly beneficial for beginners to focus on zones or try to stay in zone 2.

Only when I'm really tight, maybe a few times a year.

This is a question that 100% depends on what's acceptable where you live. 

Where I live this is pretty common - a large liberal city in Canada.

Generally different drops are fine.

Looks like it's 124 lbs if you're 5'3".

The limit was 110 ages ago and I thought it became 125 lbs some years ago?

I've donated since I hit 125 lbs (5'2") and had only one bad donation out of my 12.

I take iron pills for a couple weeks before and after each donation. I've been turned away a few times for low iron.

Well like I said, judge the context. 

I almost never initiate stuff on the subway myself because I don't really like talking to randoms.

There's a time and a place and am appropriate context. I would actually talk to someone reading a book if I'd read it before and had thoughts. A single comment is fine, and then you evaluate if the person wants to keep talking. I've had long conversations with randoms on the TTC when I noticed we had something in common (eg once it was with a fellow fountain pen user when I noticed her journalling).

But I'm also a small non-threatening person.

Think they probably get much higher traffic levels than we do.

They don't know how to stand in the subway either, always blocking the doors.

No one else gets knows WTF you're talking about either because it wasn't big news here.

I follow the news and I never heard of this.

Stay the course for my running training without getting injured or burned out. Try to sleep more. Meet more people within the LGBTQ community in Toronto.

Unless you have heart problems or something else medical going on you won't hurt yourself by having a high heart rate exercising.

Used lower end Garmin, like a Forerunner 35 or something.

Discomfort that doesn't go away with rest is a pretty big flag.

Stay to the right if you're standing on an escalator, left if you're walking. Don't block doors if you're standing on a train or bus, be aware of people trying to exit/enter. Let people out first before boarding.

Given that this is your first marathon, and that you've only done one half, and that your half was 1:47, and that you're pretty low mileage now, I would dream a little smaller for your first marathon lest you get injured.

I'm running my first marathon this October, I'm already at 40 mi/week, my best half was several minutes faster than yours, and I'm going to shoot for 3:45 for my first full this fall. My full is a full 1.5 months after yours, I'm faster and running more than you, and I'm aiming for 45+ minutes slower.

No, not beyond easier running.

Before you say anything about how I shouldn’t be heavy squatting

Why would you think anyone would say this.

1. People aren't going to post unless it makes them look good. 

2. People can say whatever they want on the internet.
