First 15km Run Training: Sports bra issues SOLVED!

I now consider myself as an amateur runner. I don't just jog, or exercise, I am an amateur runner. I specifically  train to improve my running. And I train pretty hard (...but no, I don't party harder... I don't party at all. I drink coffee and eat cakes and play with my nephew and niece and spend a lot of time programming and I looooove talking to my mommy, daddy, brothers, sister, best friend, I loooooooove going on dates with my boyfriend and spending time with him in the gym, we OWN that place, or at least that's how we act =D)

Only after a month of running, when I crossed my 10km limit, I had sports bra issues. There was NOOOO WAAAY I'd let that stop me from running. So after that blog post, I went to a Nike store and got myself the cheapest (why the hell does that word keep creeping up??) pair of high impact sports bra that fit me. It was mildly surprising that that happens to be an XS.

It kinda looks like this but it's not... It's the closes thing I found to what I bought.

I got an XS because it's the size where I can just fit in two fingers in. It felt tight but kinda comfy when I was trying it out - I did several jumps to test its "support function". The next bigger size (small, duh) was too big - and I only knew it was too big because I read How to choose the best sports bra.

I did 12km in 1hour 10mins with it. No chafing or whatsoever. It was just perfect :)
I washed it asap and I'd probably use it tomorrow for another 12km or so run - IF I can get up early enough... I'm not confident I can because I murdered my legs this morning on a leg hypertrophy program.


I feel kinda week because this morning's workout actually FELT challenging all throughout. I thought I was going to pass out keeping my core activated while I did my squats - and that was the FIRST exercise!!!

Quads
1. Squats (3 sets of 10)	45kg
2. Leg presses (3 sets of 8)	100kg
3. Leg extensions (3 sets of 12)	30kg
Hams
1. Stiff legged deads (3 sets of 10)	40kg
2. Single leg curls (4 sets of 8)	12.5kg
Calves
1. Standing calf raise (4 sets of 12)	70kg

I know I can do better, but I don't want to keep my body from recovering more quickly. I HAVE TO RUN!!!
