Do I trust my pace or gps maps?

I have my first half-marathon in two weeks time and I ran my last long run of 2 hours today.  The problem is that I don't know if I should trust my perception of pace or the route mapping programmes online? 

I know that I ran my first mile, which is usually a slower mile at just under 11mins and my last mile (also a slightly slower uphill mile) at just over 11mins.  I was out for a few seconds over 2 hours yet the route maps I have used say that I have done around 10.3 - 10.5miles but I think it should be closer to 11??  I know it is not a huge difference but it makes a big difference to me, psychologically if nothing else.  image

Can anyone comment on how accurate these route maps are and how easy it is to plot an accurate route??

Cheers, Viki
