Went out for a run on Sunday, plotted it in my head and on the way back from being a taxi for one of the brats I took a detour in the car to check the distance. I figured with the extra bit to get out to the route and home it would be about 3 miles so 5K. I did the route (killing the timer 8 minutes in by mistake), got back, plotted it on mapmyrun, 4.8K. Disappointed.
But, life goes on. So I plotted another route, it needed a bit extra so I plotted up to the next turning, yep 5K, good.
I went out this morning and did it. Managed to not kill the timer this time, was pleasantly surprised on the home stretch that I'd only been running for 30 minutes, I thought I'd been slowing down but it looks like I'm speeding up. Until I've just turned the computer on and plotted it as a route done. It's shrunk!!!! Only 4.5K. Gutted.
Oh well, Saturday is only 2 days away.
