running through the pain barrier

[mintpoppet]

I've ran for about a year. I'm not very good at pushing myself and making myself hurt/tire for a good time. How do I overcome this obstacle. I want to do a10k pb. Due to weight I am still run walking but want to be faster.

I find the first mile or two hardest when I'm in the warm-up zone.

If I know my willpower is low, I'll use the C25k+ tracks to talk me along. They focus on speed/ stamina. I've just done an 8.5 mile race 8 minutes faster than last year using them, despite the fact that I haven't gone further than 6 miles/ 10k in yonks.

There's apps for building up to 10k that would give you more structure / discipline.
