This was sent to me, and I don't follow their daily vlogs or anything but I thought this was pretty amazing. Got me pretty choked up for a bit.
This guy has lost over 100lbs, and is running a marathon.
The actual marathon (so minus all their vlogy bits about their day in the beginning) starts at 12min. And the first time she seems him (I think it was at mile 11) is at like 16:55
I loved how proud she was of her husband, and how he included the old videos of when he was overweight .
